STM32G070: ADC14 Calibration Issues: values are too low
My readings from the ADC are lower than expected. I am using an external Vref. Vref is OK. I ran HAL_ADCEx_Calibration_Start() after waiting tADCVREG_STUP . The Reference Manual says the saved calibration factor is "internally applied to the ADC".C...
Resolved! Does TxBufferCompleteCallback need to be reset? It only runs once.
I am using TxBufferCompleteCallback in order to verify that messages have been sent over FDCAN on the STM32G474RE board.I have verified that the callback is run, which means it's been activated correctly. After the first run, it is no longer called, ...
HAL_I2S_Receive not returning HAL_OK?
Hi, I'm trying "HAL_I2S_Receive" with the STM32H743, but HAL_OK is not being detected. I wrote 2 different functions - I2SWriteData and I2SReadData. For I2SWriteData, Transmit returns HAL_OK. For I2SReadData, Receive does not return HAL_OK. I2S is se...

How to set up SAI on STM32L4 for I2S on the STM32L476 Discovery Board?
We're trying to get the DAC on our discovery board to work, and we're having issues setting up the SAI ports on our dev board for I2S. Any examples would be super helpful! We're trying not to use the HAL, but there's not many examples out there wit...
