In following up with excellent tutorial for GPDMA between ADC12 and USART1 (removed 2D address) via this link
https://rristm.github.io/tomas_materials_v2/RRISTM/stm32u5_workshop/master/6_gpdma_handson_events_intro.md/
Based on the event and ioc file from STM32CubeMX and realized either ADC12 or USART1 generated an interrupt at the end of the Linked List's Node block. I figure to do this
extern DMA_NodeTypeDef YourNodeUSART1;
extern DMA_NodeTypeDef YourNodeADC;
static void GPDMA_TransmitComplete(DMA_HandleTypeDef *hdma)
{
if (hdma->LinkedListQueue->Head == &YourNodeADC) // This is working for ADC12
{
__NOP();
// while(1)
// {
// __NOP();
// }
}
// ###:ISSUE: Unable to trigger to here, have tried 4 different transfer event config.
if (hdma->LinkedListQueue->Head == &YourNodeUSART1)
{
while(1)
{
__NOP();
}
}
}
The ADC12 callback is working fine, but I am unable to get a callback from USART1.
Attached are two files.
Have I missed something?
It seems there is no configuration option to mask out interrupts from ADC and focus on USART instead?
