DMA is not working on STM32H747i-DISCO board

I am working with STM32H747i-DISCO  board and I configured ADC1 with DMA1 stream0 and ADC3 with DMA2 stream0 both with Cortex-M7 core as initializer and I created the MDK-ARM project using STM32Cubemx and compile the code in CrossWorks when I debug t...

ADC and TIMer callbacks

Hi Can anyone help me understand the difference betweena) writing control loop and obtaining ADC values in HAL_ADC_ConvCpltCallback with ADC ISRsinstead ofb) writing control loop and obtaining ADC values in HAL_TIM_PeriodElapsedCallback using TIMER I...

STM32L4 ADC reading temperature stability

Our product uses a STM32L452 to measure the 4-20mA loop current of an external sensor. The product has an operating temperature range of 0-40°C.The STM32L452 datasheet (Tables 78 to 82) lays out the accuracy specs for the internal ADC but aside from ...

Vrefint and Vts very noisy with SAI active on G4

We are using an STM32G491 with TDM audio output active on SAI. When activating the 4 MHz bit-clock on SAI1_SCK_A, Vref and temperature measurement become very noisy, while externally connected ADC inputs are not affected.See attached graph for differ...

Single AWD to monitor 2 channels from different ADCs

Hi,As from the title, is it possible to use the same AWD to monitor 2 channels from 2 different ADCs?Specifically, I have a designed a simple digitizer around a f303k8. ADC1 and ADC2 have been configured in continous mode, with AWD2 and AWD3 as monit...

Issue with ADC conversion time.

Hi, I am developing digital control for power electronics for which ADC conversion time is critically. In stm32f334r8 reference manual I saw it takes only 0.19us at lowest sampling time i.e 1.5 cycles. when I tried to measure the adc conversion time ...
