STM32 MCUs Products

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.

Generate a pulse in the STM32H7 SPI's SS line every 64 bits

I want to communicate with an SPI slave whose high level protocol states that each command is 64 bits, and that the SS line must be de-asserted and asserted in between commands. I want to send to it 2 commands as quick as possible, so I need to asser...
