CODE: # include "system.h"# include "altera_avalon_pio_regs.h"# include "alt_types.h"# include "sys/alt_irq.h" volatile int edge_capture; void Sirq(void * context,alt_u32 id) { IOWR_ALTERA_AVALON_PIO_EDGE_CAP(PIO_SWITCH_BASE, 0); IOWR_ALTERA_AVALON_PIO_DATA(PIO_LED1_BASE,IORD_ALTERA_AVALON_PIO_DATA(PIO_SWITCH _BASE)); } int main (void) __attribute__ ((weak, alias ("alt_main"))); int alt_main (void) { alt_irq_register(PIO_SWITCH_IRQ,(void *)0,Sirq); IOWR_ALTERA_AVALON_PIO_EDGE_CAP(PIO_SWITCH_BASE, 0); IOWR_ALTERA_AVALON_PIO_DIRECTION(PIO_SWITCH_BASE, 0); IOWR_ALTERA_AVALON_PIO_IRQ_MASK(PIO_SWITCH_BASE, 0xff); while (1) { } return 0; } Thanks~!Link Copied

You can't use alt_main() _and_ the alt_irq_register() function. You've got to be using a program with main(). I know that you mentioned that you had troubles compiling code with main() in it, but you have to have it if you want to use the HAL functions. (like alt_irq_register())
By using alt_main() you're telling the tools that you don't want to use any of the HAL's functionality. The count_binary() example shows you how to do this. Best Regards, - slacker- Mark as New
