ftduino's Issues

Synchronize encoder motors

Hi,

I would like to synchronize two fischertechnik encoder motors. Are there any plans for adding this feature to the Ftduino library?

Thank you

Brickly demo

Once that "Adafruit GFX Library" (https://github.com/adafruit/Adafruit-GFX-Library) is installed, the sketch compiles fine.

FtduinoDisplay.h

Vielleicht könnte das in die Dokumentation aufgenommen werden.

Manual: Mention the BT-Adapter

The manual "6.19 Bluetooth" contains no hint to the newly released BT-Adapter

I2CSlave example: motor control bug

Controlling M1 is no problem, but M2, M3 and M4 don't work.

According to the manual, the following code should set M2 to turn right at 100% speed, but instead the motor attached at M3 starts to rotate.

#include <Wire.h>

void setup() {
  Wire.begin(); // join I2C bus as master
}


void startMotor() {
  Wire.beginTransmission(43); // connect to 0x2B slave ftDuino
  Wire.write(0x04);           // set output mode of O3/M2 to...
  Wire.write(0x13);           // ... motor output right
  Wire.endTransmission();
  delay(100);
  Wire.beginTransmission(43); // connect again
  Wire.write(0x05);           // set output value of M2 to...
  Wire.write(255);            // ... full speed
  Wire.endTransmission();
}

void loop() {
  startMotor();

  delay(3000);
}

I modified I2CSlave a little bit to track the issue down in the code:
I2cSlaveDebug2.ino.txt

It produces the following (slightly modified) output explaining the bug's origin:

---- turn M1 to the right (100%) (OK) ------------
I2C receive...
addr:	0
value:	13
port:	0
reg:	0
Set output mode: 0	=	13
I2C receive...
addr:	1
value:	FF
port:	0
reg:	1
Configure Hardware...
Check passed.
PWM:	64
mode:	0
Set motor 0	to	2	at	64


---- turn M2 to the right (100%) (FAIL) ---------
I2C receive...
addr:	4	(OK)
value:	13	(OK)
port:	2	(OK)
reg:	0	(OK)
Set output mode: 2	=	13	(OK) (O3 set to motor mode)
I2C receive...
addr:	5	(OK)
value:	FF	(OK)
port:	2	(FAIL)
reg:	1	(OK)
Configure Hardware...
Check passed.
PWM:	64	(OK)
mode:	0	(OK)
Set motor 2	to	2	at	64	(FAIL)

Looks like the motor port is not calculated correctly.
Port 2 can be Ftduino::O3 (that works), but also Ftduino::M2.

Motor ports would require to be shifted 1 to the right to calculate them correctly:

• Motor offset from M1: port>>1
• M1: 0>>1 (=0)
• M2: 2>>1 (=1)
• M3: 4>>1 (=2)
• M4: 6>>1 (=3)

If I wasn't unsure of breaking the set-output commands, I would file a pull request...

Scratch3] Input hat seems to be broken

Used scratch file:

Expected behaviour:

I drag the input hat to the stage.
When I press the green flag the (hypothetical) code after the hat is exectued.

Actual behaviour:

As soon as I begin to drag the hat to the stage an exception is thrown.

FTDuino can not connect using WebUSB, Scratch nor Brickly

Hi, just got the FTDuino in the mail and wrote the first few programs, now I wanted to use Scratch so I downloaded the IOServer software as described in the manual.

On my Win10 machine when I try to connect using the online Scratch editor nothing shows up in the popup window;

When i do the same thing on my linux machine (Debian 10 Mate on a i386 architecture) usin' Chromium FTDuino shows up in de selection window, however when I try to connect. An error is returned: "Connection error: NotFoundError: The interface number provided is not supported by the device in its current configuration."
Can you please comment on this behaviour?

[Scratch3] Analog input reading functions break with invalid ports.

Used scratch file:

analog_input_broken.sb3.zip (You may have to remove the .zip to import it into scratch.

Expected behaviour:

Led goes on, then off, then on again and finally after reading from analog input (effectively discarding the result) it should go off again.
Note that I'm reading from Port "0" which obviously is invalid.

Actual behaviour:

Led goes on, then off, then on again but the reading from analog input fails, so the led never goes off.

Logo Proposal for ftDuino

Hello, I wish to cooperate with ftDuino, for this reason I have decided to design a logo for it. If you like this proposal, I can send you the files.

You can suggest the changes you think are necessary.
