Hi all, I have two files,as follows...when I simulate the sub routine is never executed. file 1(main.asm)
#include "rs_485.asm" org 0000h ljmp on_reset org 002bh on_reset: mov ie,#00h mov sp,#07h lcall rs_485_init ;initailise the serial communication end
rs_485_init: mov tmod,#20h ;timer 1 in mode2(auto reload) mov th1,#-3 ;reload value for 9600 baud rate mov scon,#50h ;8 bit,1 start,1 stop and REN enabled clr ti ;clear transmit interrupt flag clr ri ;clear receive interrupt flag setb tr1 ;Start timer 1 ret
Yeah it builds without any errors...
Have you created a project and included both files in the project so that compiler can link them together? Mahmood
Aagh! another one!! This is Assembler - so it has nothing to do with any compiler!!! See: http://www.keil.com/forum/docs/thread3247.asp Also, it is the Linker which does linking (surprisingly enough) - not the compiler!! Anyway, since he's #including the file, there's no need for linking - effectively this is just a single source file giving a single object file!
Hi all, I got the soultion,I'm posting it here so that It could help some one in future...the submodule files are include as shown below(bold text) file 1(main.asm)
org 0000h ljmp on_reset org 002bh #include "rs_485.asm" on_reset: mov ie,#00h mov sp,#07h lcall rs_485_init ;initailise the serial communication end
"I'm posting it here so that It could help some one in future." Excellent! - That's the spirit! :-)
