STM32WBA52 ADC DMA

Hello,

I'm having some trouble using adc with dma and HAL. I noticed that in function HAL_ADC_Start_DMA Length parameter is multiplied with 4. Shouldn't be 2 (16 bit data from adc)?

File stm32wbaxx_hal_adc.c line 1760 (checked with versions 1.2.0, 1.4.1)

Best regards

Hello @cvs_dk 

Thank you for reporting this. It seems to be a regression on the driver this conversation should be depending on the data width (Word, Half-Word or Byte) you can check this on the driver of the STM32U5. I've escalated internally for correction on the coming releases of the driver (under internal ticket number 192738)

Best Regards.
