Hi,
I'm looking again at LAT and PORT settings.

If the BASE PIC is sending DATA and receiving DATA and will have ANALOG inputs. The REMOTE will send and receive DATA, and have PWM outputs and ANALOG inputs. How are the PORTS set? Do I use PORT or LAT?

C.

 

To set a port pin that's output you use the LAT to set to input or output you use the TRIS

 

To set a port pin that's output you use the LAT to set to input or output you use the TRIS

Hi B,
Thanks, but your reply isn't clear to me.

E,g,
What would this look like?

18LF4431
PIN 19= ANA IN
PIN 20= PWM OUT
PIN 21= DIG IN
PIN 22= DIG OUT
C.

 

hi C,
This clip from the d/s shows how to set PORT LAT's
E

EDIT:
Added a PORTD diagram

 

TRISA = "0B00000101"
Or this
TRISA = %00000101

Your using basic It be something like that

 

Hi,
B, Correct TRISX %01010101

I will use the none enhanced type of PWM which in the case of 18LF4431 is PORTB
I'm sending and receiving digital DATA at RC7 RX and RC6 TX
APP 3x Analogue inputs on PORTA

Do I need to use LATs? if so when?

C.

 

Hi,
I've found another confused thread regarding LATs :https://forum.allaboutcircuits.com/threads/pic-programming-doubts.53209/

He's was having the same problem as I have.

It appears that LAT is a feature of some PICs, which doesn't appear to be needed so I'll carry on without using them, till something doesn't work, or I'm advised to use them.

Thanks, C.

 

Hi,
I've commented in line: PIE1.RCIE = 1 '?????????????????????????????????????

Before and after commenting in, RXErr! shows on the Terminal.
