Resolved! STM32U5A5: SAI with 24bit PCM samples - why just 16bit or 32bit?

I want to use STM32U5A5 SAI1 to generate via SAI1 a master I2S, with 24bit sample words.I need 24bit because sending out afterwards as S/PDIF (via SAI2) needs 24bit sample words (as I understand: SAI2 as S/PDIF Tx is "forced" to send as 24bit samples...

A function fails when called from an interrupt

Hi,I have defined a function, that when called, from the main.c while loop works fine. When the same function is called from an interrupt it fails to work.In debug mode I can see that the interrupt function (void HAL_GPIO_EXTI_Callback(uint16_t GPIO_...
