How do I trigger the DMA with a PWM signal in the P4100S Plus?

I am trying to generate a sine wave by using a PWM to trigger a DMA which writes a sinewave table to the IDAC. This works fine on the CY8CKIT-043 (P4200M) but when I try to port it to the P4100S Plus (CY8CKIT-149) I can get a hardware trigger to route. Can you help? I have attached my project for the P4100S Plus.

Thanks,

Hello Mike,

PSoC 4100S Plus DMA can be triggered using TCPWM triggers. I have attached screen shot for reference. Please make use of section 5.1.1 Trigger Sources and Multiplexing of TRM for more details.

Could you please share the working sample project for PSoC 4200M?

Best Regards,

Geon
