[SOLVED] pickit 1 gpasm and all that

Here is the test code:

 include         <p16c745.inc>
                __CONFIG  _CP_OFF & _WDT_ON & _PWRTE_ON & _H4_OSC
                org             0
                movlw B'00000010'
                tris    PORTA
                movlw B'00000100'
                movwf   PORTA
               
 fin: goto fin
                  end

compliled:

It does not turn on the LED.

vim +7 1.asm

I don't remember 'tris' as an instruction. It could be valid. And you need to tell it the cpu type.

My mistake.

Actually pic16c745 is just help programming. Its pic12f675 is the one I should be writing the code for.

reply is unchanged, as one pic assembler is like another.

vim +7 1.asm & fix

If you're on a pic, this has nothing to do with linux. It's hard initially, but you do it. The assembler must not complain at all.
