How to setup LPC4370 HSADC via GPDMA with external signal triggering source

[boonkongyip]

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?

Hi Boon Kong Yip,

To provide the fastest possible support I want to point you to refer to the LPC43xx CMSIS-Compliant standard peripheral firmware driver library which includes the GPDMA demo.

LPC43xx CMSIS-Compliant Standard Peripheral Firmware Driver Library (Keil, IAR) | www.LPCware.com 

Hope it helps.
Have a great day,
Ping
