Hello everybody,I am trying to use the TIM3 those input capture mode with DMA transfer. After buffer is full the DMA call the callback function IT. Then i execute the stop DMA function. But after this sequence, the DMA no reinitialize. I am using the...

Hi. I made a code that uses ADC1 in single conversion mode and UART in asynchronous mode.But when I do the ADC1_Init() for some reason the RX interrupt of the UART doesn't work, if I don't use the ADC1 it works normally. Can someone help me?Periphera...

I'm operating in normal mode, I had to include one more command to solve the problem:void HAL_TIM_IC_CaptureCallback(TIM_HandleTypeDef *htim){ if(htim->Channel == HAL_TIM_ACTIVE_CHANNEL_1) { HAL_TIM_IC_Stop_DMA(&htim3, TIM_CHA...

I have now noticed an interesting feature. The does not happen when in the first start of the DMA, only in the next sequences of pulses, after the first stop command DMA.

Hello everybody,I am using the STM32F030K6T6 device to control LEDs of the WS2812 type.For that I made a configuration of the TIM1 to use the PWM with DMA.void MX_TIM1_Init(void) { /* USER CODE BEGIN TIM1_Init 0 */ /* USER CODE END TIM1_Init ...

Can solve the problem, if someone has the same problem. The pins I'm using as serial RX and TX are the analog inputs Ain5 and Ain6, so I had to modify the following registered: ADC1->TDRL &= 0b10011111;
