STM32G474RE HRTIM ADC Injected Conversions not triggered

[vectorotter]

 

Hi there,

I am configuring HRTIM TIMD to generate PWM which works as expected, roughly following the Synchronous Buck Converter example for the DPOW1 eval board (my target is the nucleo64).

I use LL API calls instead of HAL calls for my project.  I have configured an interrup handler to service the JEOC interrupt before calling LL_ADC_INJ_ReadConversionData12()  (? - not even sure if this is correct).  I do not see my interrupt handler being called so either:

a) ADC conversion is not being triggered, or,

b) ADC conversion is triggered but interrupt JEOC isn't being generated.

Can someone suggest a way of ruling out one or the other problem?  For example, is there a blocking LL API call that will allow reading of completed conversions?  Is there an example of this somewhere for reference?

Thanks for any help in advance.

Fixed.  I was missing calls to enable the interrupt:

 

NVIC_SetPriority(ADC1_2_IRQn, 0);

NVIC_EnableIRQ(ADC1_2_IRQn);
