This can be usefull: The object "SERVER" has been improved with the "select.poll" library to make it asynchronous # esp8266.py from select import poll from pyb import UART, delay class SERVER(): def __init__(self, response): self.response = response self.uart = UART(1, 115200) self.uart.write('AT\r\...

here is a flight controller for quadcopter, hexacopter or octacopters using a pyboard:

Here I put the code for my micropython quadruped robot:
https://hackaday.io/project/6877-microp ... uped-robot

I made a board for drive my micropython tote quadruped robot... attached imgs And the code for control the servos: # timers t2 = pyb.Timer(2, prescaler=83, period=19999) t4 = pyb.Timer(4, prescaler=83, period=19999) t5 = pyb.Timer(5, prescaler=83, period=19999) t12 = pyb.Timer(12, prescaler=83, peri...

Sorry, this is the code:

>>> from pyb import Pin, Timer
>>> t4 = Timer(4, prescaler=83, period=19999)
>>> servo = t4.channel(1, Timer.PWM, pin=Pin.board.X9)
>>> servo.pulse_width(1000)

Is better that way! but I try on the pin x9 and I have an error >>> from pyb import Pin, Timer >>> t5 = Timer(5, prescaler=83, period=19999) >>> servo = t5.channel(1, Timer.PWM, pin=Pin.board.X9) Traceback (most recent call last): File "<stdin>", line 1, in <module> ValueError: pin B6 doesn't have a...

I have microservos "sg90", and I want to build a tote cuadruped robot with the pyboard so a need 12 servos.... I can move then with this code: from pyb import Pin, Timer timer = Timer(2, freq=50) ch = timer.channel(1, Timer.PWM, pin=Pin.board.X1) ch.pulse_width_percent(8) ch.pulse_width_percent(13) ...
