Hello,

I am trying to get a simple example going for the ADC of an STM32F407V discovery board.

I tried the VBAT sampling example, but so far without luck. I only get ''0,0'' via serial port on the output.

My environment is based on CooCox, and I configure the clocks (f_sys) to run on 48 MHz with HSE 8 MHz. I use DMA to transfer data from the ADC to the main display function.

How can I start/debug the setup and experiment with the different ADC modes?

Thanks!

Dear Poseid,

Debugging in Coocox is similar to other IDEs like Keil, IAR etc. Just set Configurations for your debugger. In coocox goto view>configuration>debugger, select your Adaptor and Port . Just see raw value of ADC.

Thanks, where do I find the memory address location for the raw ADC values?

As you wrote ''I use DMA to transfer data from the ADC to the main display function.''

So I hope your main display function is processing some raw data, before sending it to serial port. So in this function you can debug the raw data(received from DMA/ADC)
