Hello All,
I am very new to Chibios. Can anyone please provide me an example code to use DMA for reading ADC values? I am using STM32F4-Discovery board.
thanks in advance.
Kind Regards,
Arun

This board is really cheap (below 20$) and is an excellent evaluation platform for the STMicroelectronics Hi-Performance & DSP STM32F4 family."

Hi,
All ChibiOS HAL drivers use DMA internally when applicable, this includes the ADC driver.
You don't need to do anything special, just use the ADC driver, it is able of very high performance.
