How do I start a PIC assembly language program?
Our first PIC assembly language program can now be summarized from top to bottom:
Point the label START as the first line in the program (lines 3 and 4) Register COUNT1 and COUNT2 as variables for the delay subroutine (8 to 11) Go to bank 1 and set RB0 as output and then go back to bank 0 (lines 16 to 19)
Pic Microcontroller Assembly Language Example 1
Compile the following example code, see how variables change in mikroC debugger, and try to figure out what the code is trying to do. you will not be able to learn assembly language until you do not perform it yourself. I have made the comment with each code for your understanding.
Pic Microcontroller Assembly Language Example 2
The equivalent of the following C code in assembly is given below.Use mickroC debugger to verify your code.
Pic Microcontroller Assembly Language Example 3
Write the equivalent of the following C code in assembly. This is used to generate delay by performing no operation instructions.

mikroC Debugger can be used to check execution of pic microcontroller assembly language instructions.
WREG Register in Pic Microcontroller Assembly Language
PIC microcontroller has many registers for arithmetic and logic operations. The 8-bit WREG register is most frequently used register in PIC micro-controllers. It is often called accumulator or Working Register. It can be easily initialized with a constant. For Example: MOVLW k // here k is any 8-bit value. MOVLW 10 MOVLW 0x45 In the instruction ‘L”.
