Part Number: TMS570LS3137

Hi,

I want to setup ADC1 to run on DMA with HET triggering. Is there a tutorial or guide I can refer to get this up an running?

Thanks.

Hi Nisal,

In HALCoGen Helptopics there are several examples available

Actually, you can combine two of the examples for your requirement

1. example_hetPwm

This example will generate a PWM signal using HET module on any of the HET pins.

2. example_adcDisplay

This example will actually triggers the ADC by GIO module, so you can configure this example as HET trigger instead of GIO.

Thanks & regards,
Jagadish.

Dear Jagadish,

Thank you very much for the reply. I think I can start from here. However, is there example to setup DMA for CAN? I know there is an example for SPI DMA. But it is difficult to understand the process of DMA from that alone.

Hi Nisal,

There is no direct Example, but you can refer below FAQ to start the CAN DMA.
