HX711

[Rseliman]

Hola a todos

Hace unos dias compre uno de estos modulos con la idea de hacer un banco de pruebas ...

https://www.itead.cc/hx711-dual-channel-weighing-sensor-module.html


el tema es que todo lo que encuentro esta para arduino , y estoy intentando hacer una libreria de 0 para xc8 , por favor si alguien sabe de esto que ya existe , me podria ahorrar mucho trabajo

Muchas gracias
