STM32F7 TIM1(master)+TIM8(slave) triggering ADC+DMA issues

Question asked by HGS on Nov 27, 2017

Hi all,

 

I am working with STM32F733x MCU and having trouble achieving the following configuration through HAL library.

Following is what I would like to acheive

1) Synchronise TIM1 (master) & TIM8(slave) in slave trigger mode (TIM_SLAVEMODE_TRIGGER)

2) Use the slave timer TIM8 to trigger ADC1 & ADC2 in dual interleaved & return the ADC samples (12bit) through dma callback

 

 

Attached the main.c file generated with the help from stmcube.

I am unable to get the ADC callback triggered

 

Any pointers?

 

Thanks
