How to change the Pin Out Voltage?

[jclo13]

Hello, I am learning about lopy and I need help, how can I change the output power of a GPIO pin?, I am a little confused about the command pin.drive(), is it possible to use it in Lopy?, I need to change the output power from de maximum to 0 and vice-versa in cycles.

thank you in advance.

@jclo13 To change the output level of a digital pin, use pin.value(x) or simply pin(x). See the documentation https://docs.pycom.io/chapter/firmwareapi/pycom/machine/Pin.html
You cannot change the current an output pin can drive. But that might not have been your question.

@robert-hh I think the OP probably meant to change the voltage, which would imply using the DAC: https://docs.pycom.io/chapter/firmwareapi/pycom/machine/DAC.html

@robert-hh thank you, I used pin.value(x) and it worked, I want to simulate an oscillation using to pins, first I will put the first pin to 1 and the second pin to 0, after a time I will interchange the values, I don´t know if this is the right way, and I don´t know which lopy pins can be better for this purpose.
