For this square signal, it supposed to be dynamic values of amplitude and frequencies which submitted to my systems at different time, so I dont think that using resistors alone could help. I am expecting that I can directly send 1V, 1.5,2V maximum 3V from the pyboard to my system, can I do that?.

Thanks for replies:

Actually I am supposed to send a voltage square signal ranging from 0.5 to 2.5 V ( voltage amplitude) with low/high frequencies. In that case I dont know whether I have to send 60.6% for having two volts, or I have to go to the other solution using resistors?.

Thanks for your reply!. Now it seems that micro python doesnot have the same flexibility as arduino boards, as I need to run this on the python host as it is integrated with other parts of software. I would like to use micropython board, but this could be a dilemma as I cannot send commands from hos...

Hello,

I don't know how I can control/tune the value of the amplitude in the applied PWM as follows:

from pyb import Pin, Timer

p = Pin('X1') # X1 has TIM2, CH1
tim = Timer(2, freq=1000)
ch = tim.channel(1, Timer.PWM, pin=p)
ch.pulse_width_percent(50)

For the moment, I can connect my third party software with micropython, however, I wasnot able to power even a lead because I have to write

pyb.LED(1).on()

I dont know how micropython board v1 can be communicated with other software, any solutions?

Thanks for your reply! I understand this, but the problem how to define pyb board in python directly, I am using Pyserial, so how Pyb defined directly from my software which some part of it python code. File "serialPortController.py", line 1, in <module> from pyb import Pin ImportError: No module na...

Hello,

I am using micropython board pyb v1 and I am supposed to use it with another software SOFA framework for sending data to the board from SOFA, however, I found that rshell disconnects and sometimes doesnot work, I would be grateful if there is solution?.


Thanks,
