Hi,

 

Has anybody has experience using LPC4370 HSADC via GPDMA with external signal as triggering source?

From the UM1053 user manual DMAMUX register, it seems to me that only SGPIO 14 or SGPIO 15 can act as triggering pin.

 

What is the setup require to trigger the GPDMA to start DMA from HSADC?
