hello there, does anybody have any good complete code examples of how to use the peripheral interrupts (ie int0) on the C5402 with CCS (any imlementation). Im a newie to DSP applications (uni project) and i really need some help, the ti documentation never gives complete examples on how to setup the interrupts and i cant find any code libraries on the web either (thats another question, do any code libraries exist on the web for the C5000 dsp's?). Any help will be greeeatly appreciated. Cheers Andrew Pasquale |

For example if you want to use int0, the following are necessary 1.set the interrupt vector to the page that your vectors.asm file exists. i.e if your vectors.asm is at 0x2000 then the IPTR should be set to 0x40 (2000h/80h) 2. Enable the corresponding bit in the IMR. For int0 IMR|=1; (it's best to clear IFR before that by writing it's contents to its self IFR=IFR) 3.if you have an interrupt service routine written in C then, you should branch to that routine in your vectors file. i.e for INT0 .ref interrupt1 int0: b _interrupt1 nop nop and your c routine will look like this void interrup interrupt1() { //service code } if your routine is written in assembly then you sould mannualy do the context saving. 4. Clear the INTM.
