Problem in getting periodically reading of ADC1 multiple channels using TIM3 interrupt and DMA

On my STM32F030, I need to read analog values from three channels of the ADC1. These readings need to be periodical and I am using the TIM3 interrupt to trig the ADC value capture. When do not using DMA and collecting only one ADC channel value, ever...

In STM32F401 using ADC (4 channels in Scan Conversion mode) using DMA triggered by Timer , Data of different Channels interchanges.

I am using STM32F401CCU6 for making Oscilloscope with Waveform on display, I need to display upto 1kHz waveform in 300points. For that i am using 4Channels ADC with DMA and timer for Triggering. The code used for ADC starting :if(HAL_OK != HAL_ADC_St...

I'm using NUCLEO64 F302R8 controller, it works when I first debug the program, then it doesn't work at all. What could be the reason for this?

In my project, I convert char array components to uint_8 data type with atoi. It works fine with my project in the debug phase, then it doesn't work. I have to debug every time I want to run it./* USER CODE BEGIN 4 */ void HAL_UART_RxCpltCallback(UAR...

F411 timer1 __HAL_TIM_GET_COUNTER always return 0.

I have an F411 PCB board, for which I want to use timer 1 to generate micro-second delay.This is the init code:static void MX_TIM1_Init(void) {   /* USER CODE BEGIN TIM1_Init 0 */   /* USER CODE END TIM1_Init 0 */   TIM_ClockConfigTypeDef sCloc...

Best way to handle SPI TX when using DMA RX in SPI slave in STM32F767

I have studied how to use SPI DMA. The examples from STM32 project shows independent TX/RX.I need to handle the 16-bit data as a register. When the slave receives 16-bit data, it should echo it right away for example.​Now I can receive DMA RX transmi...

I need to PWM two RGB LEDs to control the colour output, needing a recommendation on a basic processor (e.g. low power, 48 pins, TQFP) with a pair of three output compare pins. The part selector does not have a way of sorting on this basis.
