Hi, For test purposes I need a piece of relative assembler code that blinks some Leds. I use the 'sjmp' instruction for relative jumps but I would also like to execute some relative (versus absolute) function calls. As far as I know there is no such command. I can think of pushing some return values on stack, then jumping to (not calling) a function and exiting this function with a return. How can I achieve this in a simple way? Thanks Henk |
It can be achieved with the SRC mode:
#pragma SRC
#include
void test( void )
{
printf( "Here I am!\n" );
}
void main( void )
{
#pragma asm
LCALL test
#pragma endasm
while( 1 );
}
