For a project I need to generate a clean voltage profile and found an unexpected behavior when using DAC.write(): each call of this method generates a wave on the output, even when called with the same value. So I try to use DAC.write_timed() and in this case this wave is not generated. Amplitude of...

Here's an example I coded up when I was writing the encoder support: https://github.com/dhylands/upy-examples/blob/master/encoder2.py and another example where I used the pyboard to generate a quadrature output (and looped that back to decode) https://github.com/dhylands/upy-examples/blob/master/en...

Why id type (extended / standard) is not handled the same way as frame type (RTR / not RTR)? Instead of: CAN.init(mode, extframe=False, prescaler=100, *, sjw=1, bs1=6, bs2=8, auto_restart=False) CAN.send(data, id, *, timeout=0, rtr=False) (id, RTR, FMI, DATA) = CAN.recv(fifo, list=None, *, timeout=5...

I'm using the pyboard to communicate with a product via CAN bus. This product sends and receives messages both with extended and standard ID. As the pyboard has to send message with extended ID for the product to operate, I first configure the CAN module: > with option extframe=True > and set the fi...
