InfoOnly: Got your code working on a Teensy 3.5

Just thought I would let you know that your code (at least the branch with 3.1 in it already) will work with a Teensy 3.5. The only problem I had was on initialization of the eeprom - would always default to pwm pin of 14 even after the ifdefs. If you hard code it in the setup it works fine.

THought you would like to know. Still have more work to do on it.

Can it work on mega2560?

Hi, I tried to run it on mega2560 by modifing all the defined(AVR_ATmega32U4) to defined(AVR_ATmega2560). The compling looks good but once I open the serial monitor, the Arduino IDE just be no response. I think the only difference in this case is Mega2560 need a USB chip but Mega32u4 can Connect usb directly. But I don't think it is matter in this code. Could you please help me with that?

Timer3 no longer working on T3.x

Getting back into this with the advent of the Teensy 4 and decided to retest with the T3.2. Ran into one problem since I originally tested is that TImerThree no longer drives the pwm signal for the motor of the XV-11. I am using v1.2 of your breakout though - it did use to work back in 2016.

I replaced Timer2.pwm with analogWrite's and it started working without a problem. Once I did this it even worked on the new T4.

Only other problem I am getting a bunch of errors mostly "I" - invalid data if too close - like a couple hundred mm's and some "S" signal strength. Any suggestions

Tx pin 8 usage serial communication

Hi,

I modified your code to use the Tx pin 8 to transmit data to another device. When I do this the data transmits inconsistently. For example, normally when I print to the serial monitor it give consistent 0-359 angle readings, however when I try to serial1.print(angle) the angle reports are inconsistent (sometimes it is 0-291 and sometimes it is 0-512 and so forth). I was wondering if anyone has any ideas of what is going on, because I am at a lost.

thanks,

JB

Printing Gibberish

Hi

I just finished hooking everything up - no brainer. But when I first loaded the sketch I received a series of .pid.cpp errors (a lot of different stray characters). If I delete those files the sketch loads fine but prints out gibberish. There are no errors messages printed from the setup (no I didn't miss it, I added a delay just in case). I did see one clear message about 3 ESCs or Break. That was about it before the gibberish started - its like what you see if the baudrate is set wrong. By the way yes the baud was at 115200.

I am running IDE 1.6.7 on a windows 10 x64 laptop by the way.

thanks for your help
Mike

UPDATE: I tried a second unit and it still has the same issues. By the way I tried 1.3.0 as a test.
