[yamine]

Hi,
how can i program a PIC Microcontroller in assembly and c in the same time ?
can you give me an example?
thank you,

How it's done varies depending on the compiler you are using. Look up "in-line assembly" for your c-compiler to see how it's done.

It's really easy to use inline assembly in MPLAB, but it depends on which compiler you are using.

Assuming you are using C18, check out section 2.8.2 "Inline Assembly" in the C18 Compiler Users Guide: https://ww1.microchip.com/downloads/en/devicedoc/51288f.pdf

As the users guide explains, all you have to do is wrap the inline assembly with "_asm" and "_endasm" tags. Example from the users guide:

_asm
/* User assembly code */
MOVLW 10 // Move decimal 10 to count
MOVWF count, 0
/* Loop until count is 0 */
start:
DECFSZ count, 1, 0
GOTO done
BRA start
done:
_endasm

I hope this helped!
