TMS320F28379D: Achieving two independent interrupts without delay

Jejomar Ildefonso

Part Number: TMS320F28379D
Other Parts Discussed in Thread: C2000WARE

Hi Team,

I am configuring two ePWM interrupts: ePWM1 frequency set at 200Khz (at 5μs); ePWM2 set at 500Khz (at 2μs).

I want the ePWM1 interrupt should come at every 5μs and ePWM2 interrupt should come at every 2μs without any delay between the two. Is this possible with the TMS320F28379D? If so, can you give us some guidance on how to achieve it? Thanks in advance!

Kind Regards,

Jejomar

I have not tried to do this exact implementation so I can't fully say there won't be any delay between the two service routines, it probably depends on the content you have within the ISRs. Most of the EPWM examples within C2000Ware utilize interrupts so you could reference those examples as a good starting point.

Best Regards,
