Arduino for STM32

Ok, finally got it running. What was missing was this:

extern "C" void DMA1_Channel1_IRQHandler(void)
{
HAL_DMA_IRQHandler(&hdma_adc1);
}

I'm defining HAL_ADC_MODULE_ONLY in my platform ini file. Thanks for the help






#include <Arduino.h>
#include <stm32g4xx_hal_adc.h>

// objects
ADC ...

Yes, I did try extern "C" on my callback functions, but not on the sysclock function. I'll try that and also verify that it;s entered. Thank you.

Yes, I looked at that even before I posted my thread. Nothing in that thread helped

Hello, I’m attemping to get ADC with DMA working in stm32duino/PIO for a stm32g431KB target on a NUCLEO32 baord… My Strategy has been to contruct the app using the CubeMX designer + CubeMX-IDE, make sure it works in CubeIDE,then move the code (with whatever changes are needed) into an Arduino sketch ...
