That's what I already do, studying documentation, but it will take long time, which i don't have.

Or maybe someone know how to use the RFID RC522 with pyboard?

Thank you for the replay. The thing is that I don't know python good enough to do so.

Hi all, anyone know how to change this code https://github.com/mxgxw/MFRC522-python to code that will be compatible with byboard. Thank you.

Yes, that is fine but I want use USB_VCP() to receive commands to control the stepper motor, so pyb.delay() is no good, at least for me.

Hi everyone. This is just to show, how I use pyboard to control stepper motor. Maybe someone will need it. See it in action. https://www.youtube.com/watch?v=4XYBexic-o8&feature=youtu.be import pyb accel = pyb.Accel() speed_x = 0 angle_x = 0 tim_x = pyb.Timer(1, freq=1) def stepper_x(speed, angle): g...

Great, I will stick to that. Thanks dhylands, I appreciate it!

What about this? import pyb switch_x_b = 1 # b for boolean switch_y_b = 1 # b for boolean switch_z_b = 1 # b for boolean tim_x = pyb.Timer(1, freq=1) tim_y = pyb.Timer(2, freq=1) tim_z = pyb.Timer(4, freq=1) def servo1(): global switch_x_b if switch_x_b: pyb.Pin('X1', pyb.Pin.OUT_PP).high() switch_x...

Thanks dhylands. But how can I make it, to run three steppers on different pins and speed? Must be a way to do it. The thing is in the timers, just I cannot understand how to set up three different timers and change the freq when I need to. I like Python and PyBoard, I don't want to go back to Ardui...

Yes, You right, but I tried everything and I can't find how to generate pwm to control my stepper motor. I've got this stepper driver http://www.gbeshop.com/InfoBase/downloads/M335_User_Manual-EN.pdf . In future I want three of them, each at different pin and speed. With Your code and many others, t...
