Creating a HW interrupt with DSP/BIOS

david brecht

I'm having problems setting up a HWI in the BIOS. I have a Periodic Function running just fine, but I'm still a little lost how to get a hardware interrupt working.

Any advice or can point me to the relevant documentation?

The TMS320 DSP/BIOS User's Guide (SPRU423F) is a good starting point. Check the link below;

Another source you may want to look at is the example projects supplied with SPRA958H. There are BIOS examples provided that use the HWI for an ADC interrupt. This will give you a good working example. SPRA958H is available at the following link:
