ADC-DMA multi-channels trigger based on NXP MCUxpresso SDK - KE15&LPC51U68

[#1]

Hi:

This thread mainly introduces how to sample multi channels ADC with DMA. The slides is in Chinese.

For different MCU family, Kinetis & LPC has different ADC & DMA system. There takes KE15 & LPC51U68 for example, introduce how to enable various ADC & DMA trigger solution.

1.KE15:Three sample projects include:

1.1 LPIT HW trigger ADC & DMA transfer, enable interrupt for get ADC value;

1.2 LPIT HW trigger ADC & DMA transfer, DMA will automatically trigger next transfer;

1.3 Software trigger multi-ADC & DMA transfer; 

2.LPC51U68: Two sample projects include:

2.1 Software trigger multi-ADC & DMA transfer; 

2.2 SCT HW trigger ADC & DMA transfer, DMA will automatically trigger next transfer;
