16f1937 mikroC problem

[ahmed]

Hello , I want to interface a keypad and LCD with pic16f1937.

Everything is working fine over 16f877a but with controller it is not working at all.

Project folder and Proteus simulation file is attached , any help would be appreciated.

Hi Ahmed;

First, set ANSELA to zero so that you can use the PORTA bits as digital I/O.
Second, to avoid RMW problems use LATAx bits to define the LCD module connections (instead of the RAx bits).

Study the datasheet!

I am bit confused with these datasheet variables , studying about mikroc (newbie)

Can you give me any good example please?

or modify the code , if possible.

Edit:
By the ANSELA=0; solved the problem

I took the time to take a look!!
pic16f1937 portA output I/O
Execution can be displayed!!

This website has some examples of mikroC Projects pic18F!!
But there is no pic16f1937 chip!!
