18F25K80 OneWire library

#1 Post by Bonca » 10 Aug 2022 23:23

Dear Support,

I need an advise how to get the 18F25K80 working with DS18B20. It seems that the OneWire library does not work properly on that controller. Do you have a similar solution like this?

Thank you in advance.

Works OK for me using RA2 for DS18B20 ...

Maybe you did not make the correct changes when changing processor?

Attached is mikroE demo code, adjusted from PIC18F45K22 to PIC18F25K80 and for DS18B20 on RA2

Hi hexreader,

thank you for testing on 18F controller. I have prepared my own OneWire library taking in consideration the TRIS, LAT and PORT registers.
