CCS/TMS320F28377S: ASM ISR for EPWM1_INT

There is no example for exactly this, but you can implement it quite easily.  If you open the "adc_soc_epwm_cpu01" example for your device in the latest version of C2000Ware, you can add the attached file to the project, and make the following changes to the code in "adc_soc_epwm_cpu01.c":

1.  In Line 65, add

extern interrupt void asm_isr(void);

2. Change line 129 to:

PieVectTable.ADCA1_INT = &asm_isr; //function for ADCA interrupt 1

Then build and run the code as you normally would.  Set a break-point on line 8 of the attached file and you should hit it every time.  It it for you to add any necessary assembly code where indicated.

Hope this helps.

Regards,

Richard
