Hello,Here is my DMA and USART configuration:(BaudRate=2250000)DMA_InitTypeDef DMA_InitStructure; NVIC_InitTypeDef NVIC_InitStructure; RCC_AHBPeriphClockCmd(RCC_AHBPeriph_DMA1, ENABLE); NVIC_PriorityGroupConfig(NVIC_PriorityGroup_2); NVIC_In...
Hello.I am using the STM32L4 series.I want to send the ADC converted sensor value to the PC via UART communication.I started ADC in /* USER CODE BEGIN 2 */ zone of "main.c" output from CubeIDE, but it failed.When the start instruction is given twic...
Hello everybody,I'm trying to learn about stm32 microcontrollers and I thought the best way to do that was to start with assembly (well, maybe I was wrong about that, but I started with that). I'm just trying to turn on the user led on my nucleo stm3...
Hi, I have a code in which I am controlling a PWM output in Center Aligned Mode using Timer 2 Channels 2 (inverted polarity) and 3, both having their duty cycles changed by the functions:__HAL_TIM_SET_COMPARE(&htim2,TIM_CHANNEL_2,(duty_c-0.05)*400);_...
Hi everyone,I am using an STM32L412KB chip and I currently have an ADC channel configured to trigger a conversion on the rising edge of TIM15. I have the timer setup to be a 1kHz square wave. In the ADC interrupt handler I toggle an LED on my board, ...
I have a STM32L031K6 Nucleo Board...I want to use the DWT.. but I become this errors:../Core/Src/../Inc/stm32_delay.h:35:30: error: 'DWT' undeclared (first use in this function) uint32_t clk_cycle_start = DWT->CYCCNT;How can I Use DWT or Enable it...
Hi, I'm not being able to make LPUART work.What I tried:Use HAL drivers.Clock LPUART with LSE.Use different board.I also configured PB11 as output and it toggles normally.PB11: TX(output)PB10: RX(input)This is my code:LL_IOP_GRP1_EnableClock( LL_IOP_...
We have a system that uses hundreds of modules. Each module has 4 STM32F303 MCU's. Within a single module we would like to have one programming interface. Is there a means to program 4 MCUs with one programming interface?
Hi everyone,I can write to flash of STM32F103, max value of uint32 variable 4294967294.It is possible to write when you write it to flash directly.But I want to write it to flash with uart receiving. But when I put the rows (which is writed Bold in c...
Hello,I'm trying to understand: When will the HAL_UART_Receive function return HAL_TIMEOUT ?Will it happen only when the "Timeout" value has passed ?/** * @brief Receive an amount of data in blocking mode. * @note When UART parity is not enable...
