PIC18F45K40 PORTD pullups
PostPosted: Sun Feb 19, 2017 4:50 pm     Reply with quote
Hello!

I’m trying to set the internal pull-ups on PORTD in a PIC18F45K40. In the other ports I used port_x_pullups(), but in PORTD this function is not implemented. Verifying the PIC datasheet I found that PORTD have internal pull ups. How I can set this pull-ups?

Thanks

Add this code above main(). Then you can use the function.
Code:
#byte WPUD = getenv("SFR:WPUD")
#define port_d_pullups(x) WPUD = x

Usage:
Code:

port_d_pullups(0xFF);  // Enable pull-ups on all PortD pins

Also, this needs to be reported to CCS support so they can add it.
