STM32L562 Using TIM1 to trigger ADC1 Ch1 sampling at 5 kHz with DMA1 storing to a circular buffer. Stores 12 samples, then no further samples stored. What can stop this chain from functioning?

Here is the setup (Using timer 1 - 16 Mhz clock, counter = 3200) using OC channel to produce scope signal on output pin):void MX_TIM1_Init(void) {   /* USER CODE BEGIN TIM1_Init 0 */   /* USER CODE END TIM1_Init 0 */   TIM_ClockConfigTypeDef sC...

ADC reading error

I am using stm32f334r8 for digital power control. I have configured ADC using cube mx Lower level. ADC reads 0 for 40mv input even though ADC is configured to 12bit and 181  sampling cycles. I also tried calibrating ADC before conversion is started. ...

STM32H735 ADC DMA Ethernet memory issue

HiI have implemented ADC1 on a DMA and verified its operation. I then implemented the ethernet stack and verified that it can be pinged. The issue I'm having is that the ADC DMA stops working once the ethernet stack is implemented. I believe the erro...

Internal Temperature STM32H7 delivers wrong value

I read the messages in here about wrong temperature values including code examples, but still getting wrong values:I need to measure the internal CPU temperature sensor from the STM32H743XIH6. I activated the ADC3 using STM32CUBEMX (V. 6.9.2) and sel...
