dxcore's Issues

Adapt Optiboot bootloader

These chips cry out for a serial bootloader! The flash write proceedure is different... but hardly difficult...

Error in README

Hi DrAzzy,

In the README you state:

And all parts will have the following defined:

• AVR_DA
• DxCORE

DxCORE should be DXCORE.

Best,
Flössie

Adapt Logic, Analog Comp library. Add actual DxCore library to supply some helper functions

Logic will be trivial, analog comp. looks easy too.

DxCore library would be a good place to put the autotune related calls,

Pinout diagrams

We need pinout diagrams for the AVR DB series as well. I'll see what I can do about this.

After #15 is merged, all pinout diagrams need to be updated to indicate that the ZCD hardware is actually there and fully supported by DxCore.

Pull in new version of Logic

Some issues were fixed in MegaCoreX version of logic, need to pull that in.

Unified event system library for mega0, tiny0/1/2 and AVR-Dx

Hi!

I have an idea I'd like to discuss with you. As you already know, the event system is pretty powerful and certainly useful if you can wrap your head around it. I wasn't really able to do just that before I really deep dived into the datasheet. And then it appeared to me; It's very simple! A lot simpler than the CCL hardware!

I'm sure other users will find the event system useful, and even easy to use if they have a sleek library to work with. So what do you think about creating a library that works for MegaCoreX, DxCore and megaTinyCore? I can create a working library for MegaCoreX, and you can modify it to work with "your" hardware? According to the datasheets I've read, the event system hardware are very similar across these three "hardware families".

Some documentation suggestions

Thanks for providing this core! I've just successfully uploaded Blink to an AVR128DB28 on a breadboard.

Couple of comments:

1. Using a Nano-based UPDI programmer I previously used to program 0-series and 1-series chips, I got the error:

   avrdude: jtagmkII_paged_write(): timeout/error communicating with programmer (status -1)
   

Thanks to the issue by @DustinWatts I realised I need to update jtag2updi, and it then worked. Perhaps mention this?

2. The link Making a cheap UPDI programmer in megaTinyCore (now) gives a 404.

Can't disable millis()/micros() timer

Hi DrAzzy,

When setting "millis()/micros() timer" to "Disabled", I get this:

Arduino: 1.8.13 (Linux), Board: "AVR DB-series (no bootloader), AVR128DB28, 24 MHz internal, No, 1.9V, Disabled/Disabled, EEPROM retained, Hardware Reset (recommended), Disabled, Enabled, 8ms"

Error compiling for board AVR DB-series

I get this error with optiboot and without optiboot. Using standard libraries and latest IDE

EEPROM library not working

Arduino 1.8.13, macOS 10.13.6

AVR128DA28 DIP package w/Optiboot

EEPROM writes not sticking, e.g.

EEPROM[34] = 10;
Serial.println(EEPROM[34]); // prints 255

I haven't got jtag2updi working so I set the fuses and programmed the bootloader using pyupdi. I based the fuse settings on the avrdude command line displayed by Tools->Burn Bootloader

Everything else seems to be working so far.

Edited to add -------

avr-libc routines don't work either, e.g.

#include <avr/eeprom.h>

  if (eeprom_is_ready()) {
    eeprom_write_byte((uint8_t *)1, 22);
    eeprom_busy_wait();
    Serial.println(eeprom_read_byte((uint8_t *)1));
  }

Use DxCore with AVR128DA48 Curiosity Nano Evaluation Kit?

Is it possible to use the DxCore with the AVR128DA48 Curiosity Nano Evaluation Kit?

https://www2.mouser.com/ProductDetail/Microchip-Technology/DM164151

I tried uploading Blink, after selecting Atmel nEDBG (ATSAMD21E18/Curiosity) from the Programmer menu, but get:

avrdude: bad response to AVR sign-on command: 0xa0
avrdude: retrying with external reset applied
avrdude: bad response to AVR sign-on command: 0xa0
avrdude: retrying with external reset applied
avrdude: JTAGEN fuse disabled?
avrdude: initialization failed, rc=-1
         Double check connections and try again, or use -F to override
         this check.

Version 1.0.1 "device-specs/specs-avr128da64: No such file or directory"

Hi!

Version 1.0.1 gives me an "avr-g++: error: device-specs/specs-avr128da64: No such file or directory" error.

Version works fine and a simple blink sketch complies without error.

Edit (to be complete): Arduino version 1.8.10, MacOSX.

jtag2updi compilation errors (any avrdx target)

When compiling the jtag2updi firmware, getting multiple warnings:
#warning "Part not supported - if you didn't provide all the needed pin definitions, that's why it's not compiling"
Using DxCore 1.1.0-a with Windows 10 and Arduino 1.8.13

Arduino IDE v1.0.1 is not seen in the board menu

After updating the DX core form v1.0.0 to v1.0.1, the boards are nor more present in the Tools/Board menu. The core is listed in the board manager.

DAC_ENABLE should be DAC_ENABLE_bm

Simple mistake in the readme.
DAC0.CTRLA|=(1<<DAC_OUTEN_bm)|1<<(DAC_ENABLE);
should be
DAC0.CTRLA|=DAC_OUTEN_bm | DAC_ENABLE_bm;

Pull in TCD0 PWM enhancements from megaTinyCore

some pwm enhancements and fixes recently went into megaTinyCore relating to TCD0 PWM. They should be pulled in here; it is a drop-in change, though we want to get the compiletime sanitychecking implemented first, as those changes go into the same functions and we should get both of them in at the same time.

EEPROM addressing goes wrong above 256 bytes

The following demo program illustrates this. It should write into the 512 bytes of EEPROM on an AVR128DA48:

0 0 1 1 2 2 3 3 4 4 ..... 255 255

Program:

#include <EEPROM.h>

void setup() {
  Serial1.begin(9600);
}

void loop() {
  for (int i=0; i<512; i++) EEPROM.write(i, i/2);
  Serial1.println("Read");
  delay(1000);
  for (int i=0; i<512; i++) { Serial1.print(EEPROM.read(i)); Serial1.print(' '); }
  Serial1.println();
  delay(1000);
}

Default state of "MVIO on PORTC" menu option

The initial state of the MVIO on PORTC menu option seems to be Enabled.

Wouldn't it be more logical to swap the order of the options, and make the default state Disabled, as this is the setting without an explicit fuse change?

Consider if any of the wacky possibilities with clock on event are useful for millis

Imagine you dedicated two type B timers for millis()/micros(), in the cascade (32-bit input capture) configuration. You now have 32-bit counter right there, and you can take a "snapshot" of it with an event (like, oh, software strobe)... if you clocked the low timer from event too....? Run it from TCD0 OVF, prescale by 4 or 8 for 16 or 32 system clock, set TCD top to 3999 - or use a TCA or third TCB? Bunch of ways to maneuver that, and you could still generate PWM if it was TCD0 or a TCA, just have to be a bit more clever... (it's all shifts to convert from 255ths to 4000ths.... TCD and the TCBs could all capture on same event? And you could have an all-hardware-no-interrupt millis... I think you can also use self-interacting LUTs to generate event signal derived from the system clock that is effectively prescaled clock (that 2 or 4 cycle delay from filter being the key), and clock TCBs from that? There is a lot of bizarre for doing weird stuff with it...

Make optiboot fit in 512b!

It already fits on the 32k parts, and I'm 7 instruction words away from 512b on the 64k ones, and 15 instruction words away on the 128k ones....

TCB2 disable and onboard ATSAMD21E18 Programmer use?

Hello,

I would like to ask why the timer TCB2 cannot be switched off? In the board selection menu this is provided, but it causes a compiler error. I want to configure all timers myself and I also need the TCB2 interrupt vector which remains blocked. Can you implement the millis/micros "disabled" internally real? So that no millis and no PWM is active by default.

I also want to ask if you can extend the controller package to flash the AVR128DB48 Curiosity Nano Board via USB?

MCUdude has this built into its MegaCoreX package. You select the Atmel nEDBG (ATSAMD21E18) on the board as programmer and can flash via USB as usual. Would that be possible? The SAMD21 is the same. https://github.com/MCUdude/MegaCoreX#curiosity-nano

Otherwise, best thanks for the controller package.

Add support for clock/crystals to wiring.c

Looks easy to do, just gotta do it. Right now the menu options don't actually work.

Add Opamp library in the spirit of ZCD, Logic, and Comparator

The DB series has a sick set of on-chip opamps. Really cool stuff. I don't do much with analog, as it happens, but it sounds like these are to analog what CCL is to digital logic. They very much lend themselves to a similar library.

broken Images/Links

all imagines on this page are broken:

and the link to the page "Making a cheap UPDI programmer" is broken on here:
https://github.com/SpenceKonde/DxCore/blob/master/Wiring.md

speaking of that page, it mentions the ATtiny a lot, even though it's for the AVR128Dx series? i assume it was just copy&pasted from another core.

Support for AVR128DA48 Curiosity Nano

Can you support the AVR128DA48 Curiosity Nano? The upload should work like the ATMEGA4809 Curiosity Nano, it is the same chip for UPDI Debug. Atmel nEDBG, see MegaCoreX.

Add support for serial adapter updi programming pyupdi-style

pymcuprog support is going into 2.2.0 of megaTinyCore for programming using a serial adapter as a UPDI programmer.

Curiosity Nano will be supported by avrdude.

[Question] Why have separate manual and boards manager release?

I see you're doing this for this core, megaTinyCore, and ATTinyCore. Why not only do one release, and instead make the release script remove the avr/megaavr folder?

For reference, here's the release script I'm using. All I do is to publish a new release and run the script. It pulls the latest release, removes the avr/megaavr folder, compresses it into an archive again, and appends the json file.

I just had a look at your ReleaseScripts repo, but I couldn't really find the script you're using. Are you doing the boards manager stuff manually?

Compiler error for non 128K parts

Great to see the new DxCore release!
All 128K parts compile fine, but getting errors for the 64K and 32K parts.

We need Wire1 library that is compatible with Wire

Edit by Spence The version of the Wire1 library referred to here has been pulled from the core for v 1.3.3 and later, since it was unfit for any purpose largely due to this issue. We still really should have a Wire1 library, and the one to which @MCUdude links is an example of how this has been done on classic AVR cores. We need the same thing here, but I don't really know how to approach it. If anyone here does, you'd be a hero if you could lend a hand on this front... Thanks!

As you already know, the Wire1 library really doesn't have anything to do with the Wire library. They are separate libraries, and they have different class names, TwoWire and TwoWire1. This is fine if you're using the library as it is, but not so good if it is used within a library or passed through a constructor like I know lots of the Adafruit libraries do. In this example, there is no easy way to use the TWI1 hardware with the MCP4725 library.

The Wire and Wire1 libraries should ideally come from the same class, TwoWire. This may sound like a difficult task, but it has already been done for MiniCore (ATmega328PB) and MightyCore (ATmega324PB). @asukiaaa was so kind and did all the hard work for me a while ago. It should at least be considered 🙂

avrdude: jtagmkII_paged_write(): fatal timeout/error communicating with programmer (status -1)

Hi!

Using jtag2updi on an ATMega328p with a FTDI231. After successfully burning the bootloader to an AVR128DA64 I get the following error:

avrdude: jtagmkII_paged_write(): timeout/error communicating with programmer (status -1)
avrdude: jtagmkII_paged_write(): fatal timeout/error communicating with programmer (status -1)

I tested the chip using MPLABX and a PICkit4 and it programs fine.

Might worth mentioning on fuse5 and fuse6 i get an error when burning the bootloader:

split up init() into weakly defined sub-functions

These should optimize away with no space or performance cost - but they will enable myriad enhancements by allowing libraries or user code to override pieces of the initialization process in order to provide new functionality or prevent the core init() functions from interfering with desired behavior. Should be trivial to implement, will first add to megaTinyCore.

Add support for higher clock speeds to builtin neopixel library

I've calculated the delays. The constraints that were so tight at 8 MHz give way to busy-wait loops at 24+

Of course, some of this work may end up being unnecessary - it remains to be seen how far we can push the clock speed on these... but I;m an optimist :-P

Writing to flash from app w/out bootloader

We do not have enough flash to do it the "usual" way here with the do_nvmctrl

But that's A-OK because there is a much more graceful and powerful way to do it. There is only one operation to which the write protection applies, and that is to the SPM or SPM Z+ instruction (or ST if operating through the mapped flash, which is bugged on AVR128DA hardware currently, and since that's what most people are playing with, a solution that is bugged for them isn't ideal)

So, just before the Optiboot version (ie, at 0x01FA), I put two instructions : SPM RET. That means an application-writing-to-flash would set up the NVMCTRL.CTRLA register and then jump into an inline assembly snippet to stuff the values into r0 and r1 (why did avr-gcc have to pick r1 as their known zero, when the manufacturer uses r0 and r1 for so much special stuff?), set the z pointer to the target address - just like they were going to call SPM themselves - but instead, JMP to 0x1FA bootloader section executes the SPM instruction and then returns...The implementation can also be better aligned with the chip's capabilities than the rather awkward previous optiboot method.

This will be implemented in the flashwrite.h library alongside the latest bootloader versions.

So - the next question is whether we can do something similar without the bootloader? What if we made APPCODE really small, and like almost everything reside in APPDATA so it could be rewritten freely as long as the actual SPM instruction was near the beginning of the program. The only problem I am aware of is that eeprom would also need a workaround, since APPDATA can't write to EEPROM naturally.

SPI1 library doesn't work

I attempted to copy the SPI library, replacing every instance of SPI with SPI1. On Wire, despite having to do it to more files, and far more functions, this worked fine, but my SPI1 library gets WACKY errors. Anyone want to look at it and see what the hell I did wrong?

Serial is unstable under some circumstances

Came out of #32 - I think the fix we need was luckily already implemented on megaTinyCore with the massive refactoring of Serial. This will also get us higher maximum serial speed, too. I had a terrible suspicion that the way it messed with interrupt priority was a disaster waiting to happen (and indeed which started happening in an issue report around the time I was fixing it...) can produce far more severely broken behavior in readily accessible situations on DxCore as well, to the point where I am inclined to consider Serial totally busted here. This is an extremely high priority issue!

`initVariant()` in `variants/28pin-standard/pins_arduino.h`

Hi DrAzzy,

You define initVariant() in variants/28pin-standard/pins_arduino.h. This doesn't seem to work in conjunction with the Arduino_FreeRTOS_Library which overrides the weak symbol:

I had a look at MiniCore, which compiles fine with the Arduino_FreeRTOS_Library. There it's done in main.cpp. Moving

void initVariant() __attribute__((weak));
void initVariant() { }

from 1.2.0-a/variants/28pin-standard/pins_arduino.h to 1.2.0-a/cores/dxcore/main.cpp solves the problem.

Best,

As the question states, there is no pinout image for any MCU from the DB-series.

I am planning to migrate from AVR128DA64 to AVR128DB64 in my project so as a second question, how does the pinout and peripheral pins differ from the DA-series and DB-series MCUs I mentioned?

Thank you.

DAC documentation correction

Your example for using the DAC should either be:

// enable DAC
DAC0.CTRLA |= DAC_OUTEN_bm | DAC_ENABLE_bm;

// write value to DAC
DAC0.DATA=(dacvalue<<6);

// disable DAC
DAC0.CTRLA &= ~(DAC_OUTEN_bm | DAC_ENABLE_bm);

or:

// enable DAC
DAC0.CTRLA |= (1<<DAC_OUTEN_bp) | (1<<DAC_ENABLE_bp);

// write value to DAC
DAC0.DATA=(dacvalue<<6);

// disable DAC
DAC0.CTRLA &= ~((1<<DAC_OUTEN_bp) | (1<<DAC_ENABLE_bp));

`specs-avr128db28` missing?

Hi DrAzzy,

I've just got some t1614 and AVR128DB28 from Microchip direct. I smoothly got started with the t1614, but now I've got a problem with the AVR-DB using DxCore. Whenever I try to compile, I get this:

avr-g++: error: device-specs/specs-avr128db28: No such file or directory

I've got IDE 1.8.13 and DxCore 1.2.0. Do I need to update the Arduino toolchain?

Thanks,
Flössie

"Error compiling for board AVR DA-series (Optiboot)" with the Adafruit GFX Library

Program I'm trying to Compile/Upload: PASTEBIN
(that exact same program compiles fine for the Arduino Nano and Mega2560)

Error Message: PASTEBIN

All Libraries i have are up-to-date.

Is there any more information needed?

Do SPI correctly

Came out of #32.

We cannot do what we had hoped with an SPI_1 library; although better implementation of that functionality could work, unlike the current implementation (which is basically unusable in all situations in which it would be desirable), the fact that io.h names the peripheral SPI1, which is what libraries expect the library controlling it to be makes this approach untenable. Too many libraries with too many users are already present in the wild.

Instead, SPI.swap() will be adapted to take an argument of the form (USE_SPIn | pinswap), where n is 0 or 1; USE_SPI0, USE_SPI1 will be defined by SPI.h as (n<<4), that is 0x00 and 0x10. This is of particular importance for 28 and 32-pin parts, especially where an external clock or crystal is used; in that case, the only pins available for SPI0 are shared with the USART0 alternate pins, and USART0 default pins are used by the external clock source. As using a different serial port for Serial would represent a confusing departure from convention, this would be an inevitable pain point for users - this seems to be the best approach here (and it's up to the user if they want to do something with both ports at once - I think that this use case basically doesn't exist)

Undefined reference to `ccp_write_io()`

Hi DrAzzy,

I'm using your DxCore 1.2.0-a under Linux with an AVR128DB28. When trying to use the ccp_write_io() function from <avr/cpufunc.h> I get a linker error.

I'm looking for a workaround right now. Just wanted to get you informed...

Best,

Workaround for "ADC disables digital input" not working

On an AVR128DA28 I can't get PD0 to work as an input. For example, an LED on PA7 doesn't light with the following example:

void setup() {
  pinMode(12, INPUT_PULLUP);              // PD0
  pinMode(7, OUTPUT);                     // PA7
}

void loop() {
 if (digitalRead(12) == HIGH) digitalWrite(7, HIGH); else digitalWrite(7, LOW);
 delay(1000);
}

It works if you do:

analogRead(7);

in setup().

Missing EEPROM library

Just tried compiling an existing project for DxCore and tripped over the missing EEPROM.h.

What's the status of this library ? Possible ? Coming ? Not happening ?

Not the end of the world as my design has optional outboard I2C EEPROM, but support for the on-chip EEPROM would be nice.

I tried searching through the repo and google.

Thanks.

Things relating to pinout images

Discovered what I'd uploaded had too much whitespace, but by then github was caching it, so had to upload both fixed copy, and one with new name to fool the cache.

Remember to remove one with altered name before next release - cache will have updated by then.

Also, FFS, the images need to be pulled from future board manager releases. There is no need to make people download 30MB of high-res images that will be hidden in a not-meant-to-be-used-by-humans Arduino15 folder...

Can we condense the number of options on the boards menu?

The menu is already getting kinda long, the entries are almost identical, and the DD series is still on the way.... I'm pretty sure it can be shrunk waaaay down.... (and no, I didn't add all those entries manually. Hurray for regex find + replace)

add printf() support

MegaCoreX has this. DxCore and megaTinyCore should, but don't.
