Hi everybody, I'm trying to realise an interrupt generated by the timer but unfortunately the code lines included in the interrupt program (i hope this is clear enough)are never done. I read the documentation about the timer and also about interrupts, but i don't succeed in understanding how i must tell the DSP to go to my interrupt program whenever the interrupt generated by the timer happens. Can someone give me a code example (in C if it's possible) so that i understand (with explanations too). Thank you very much. Here is a sample of my code. I f you see something wrong please tell me about it. " void main(void) { brd_init(100); *(volatile unsigned int *)0x0007 |=0x0800; *(volatile unsigned int *)0x0007 &=0xFEFF; *(volatile unsigned int *)0x001D =0x00F8; *(volatile unsigned int *)0x0000=0x0000; *(volatile unsigned int *)0x0001=0xFFFF; *(volatile unsigned int *)0x0026 |=0x0010; *(volatile unsigned int *)0x0025=0xC34F; *(volatile unsigned int *)0x0026 |=0x0001; *(volatile unsigned int *)0x0026 |=0x0020; *(volatile unsigned int *)0x0000 |=0x0010; *(volatile unsigned int *)0x0007 &=0xF7FF; *(volatile unsigned int *)0x0026 &=0xFFEF; for(;;); } interrupt void toz (void) /* Here i don't know how to declare this */ { *(volatile unsigned int *)0x0007 &=0xDFFF; /* bit XF=0 */ *(volatile unsigned int *)0x0007 |=0x2000; /* bit XF=1 */ } " I removed the comments because they were in French. Hope someone can help me once again. Thanks. Jerome |
