Software Trigger for ADC with eDMA

[SpeedyGonzalesss]

Hello,

I am using i.MX RT1176 and MCUXpresso IDE. I want to use ADC with DMA and trig with software. I made some settings. It works in a single cycle. However, when I want to trig the ADC again after the DMA callback arrives, the DMA callback does not work again. How can I run this structure over and over again in software?

Thank You,

Speedy

When you change the following registers, it automatically reads ADC and DMA callbacks for the same address over and over again. But how can I set this via the config tool rather than manually?

Hi,

Thanks for sharing your work. On my side, I also didn't find a way on how to do the corresponding configuration via ConfigTool. Probably logically, the logic in the callback function, including the code for operations such as clearing the marker bit, is something that the customer needs to add on their own.

Best regards,
Gavin
