GPIO produces square wave//producir onda cuadrada con el gpio

roberth-
roberth- over 8 years ago

Hola!

necesito generar una onda cuadrada simétrica de 10 khz y que pueda ser mas alta en caso de ser necesaria (quiza hasta los 90-100 khz pero no mas)

el inconveniente es que recién empiezo con el raspberry pi y no manejo python todavía se que el gpio puede emitir esta señal pero no tengo idea de como.

 

Gracias!!

 

Hi!

I need to generate a symmetric square wave of 10 kHz and that can be higher if necessary (maybe up to 90-100 kHz but not more)

The problem is that I just start with the raspberry pi and do not handle python (I just started with linux)

I still know that the gpio can emit this signal but I have no idea how.

 

 

Thank you!!

    Here is code and article showing a generator RPi GPIO as a high-speed square wave generator - Raspberry Pi Stack Exchange . But is has limited functionality since the code run under linux and so the wave may vary slightly at times. Do not use or run other programs while exercising this code.
