Issues with Jetbot #4

Open xpeedster opened 3 years ago

xpeedster commented 3 years ago

Hi, I am trying this library with the Waveshare Jetbot, and the thing is I am able to spin the motors, but not able to change de speed.

Thanks for the help.

Thanks for reporting! I'll take a look as soon as I can.

I took a much deeper look at it, checking the Jetbot code Waveshare has (which is written in Python, and uses the original python library) and they make extra calls to setPWM command.

I made it work adding some extra lines to the "adafruitdcmotor.cpp" (and obviously changing the header too).

I will share as soon as I can if you want me to.

Thanks for the reply tho. ^^

Hi @xpeedster, could you please share the JetBot compatible code? Thanks /Ágoston

@xpeedster Thank you very much, I would appreciate too much you could share the way you solved it

little bit late here, but just change the path for i2c device to always return the correct path for the jetbot, e.g. std::string getFilenameForBus (int busNumber) { return "/dev/i2c-1";// + std::to_string (busNumber); } instead of the RPi bus. Works without any issue for me
