Ls,
I encountered a strange effect.
setting the pic to 4 ana in ana4-ana7 external vref.(2.5V)
Changing the voltage on the ref pin no effect on measured value ?? (ra1 pin18).
It is reading a inputs but instable.
a real war to get this to work I strapped dwn the program and left the ana parts.
I did something wrong but don’t know what. code attached..
Help will be appreciated.
regards,
Joop
