There was an error in the docs indicating any() returned a boolean, corrected recently. I also ran into the error that there is no pin named pyb.Pin.board.PA2 I use a 2015/10 firmware version. I have recently tried to update but i had problems with pin names etc, so i downgraded again. In my board,...

Well, i have read the documentation and tried to fix this in many different ways (using bytearray / readinto() ) but it still doesn't work :cry: from pyb import UART BT = UART(4, 9600) BT.init(9600, bits=8, parity=None, stop=1) def speed(speed_percent): pulses.channel(3, pyb.Timer.PWM, pin=pyb.Pin.b...

I am getting MemoryError when trying to control my car's speed via Bluetooth :cry: pulses = pyb.Timer(2, freq=1000) pulses.channel(3, pyb.Timer.PWM, pin=pyb.Pin.board.PA2, pulse_width_percent=100) pulses.channel(4, pyb.Timer.PWM, pin=pyb.Pin.board.PA3, pulse_width_percent=100) def speed_adj(R_mot_pe...

that is correct. Thanks, I ll try to fix it

mode_1 = False def mode1(): execfile('/flash/mode1.py') /flash/mode1.py: if mode_1 == True: mode_1 = False pin1.low() execfile('/flash/main.py') else: mode_1 = True def do_stuff(): pin1.high() while True: if BT.any() == True: execfile('/flash/main.py') else: do_stuff() mode1() -> pin ON mode1() -> ...

startup value: mode = False This works up to 10 times, then: any idea how to fix it?

Thanks for all of these info, pc MicroPython has been designed to minimise RAM usage. The bottom line is that you can write quite large applications. Thats great. I think this RAM is more than enough for my application. After some thoughts, i ordered the STM32F4DISC so i can have a backup plan if i ...

I'd like to get the pyboard but i need bluetooth module for pyboard too.
With JYMCUHC05v1.06 being out of stock, i found this one: MOD-nRF8001

Anyone knows if that is compatible with the pyboard?

without knowing more about what you're building it's hard to be definitive. Its still an open project. I am thinking of a simple car with 2 servo for the movement , 1 servo for the turn. Manually Controlled via BlueTooth, maybe with an android application. Thats the minimum requirements. Could add ...

Hi community! I am new here, new in programming and about to start a project (a Bluetooth controlled robot). I need to choose a board for that. My optrions are: STM32-103STK , STM32-405STK and the pyboard . Should i do that on C or microPython? Can i run MicroPython on all of them? Any info or tips ...
