i'm using STM32F730 as uart receiver and STM32f0 as uart transmitter baud rate 9600, 8 bit data representation. i'm using DMA with interrupt for the communication. i'm using HAL for programming on IAR workbench. The transmitter is continuously transm...
I'm trying to inject a simple wrapper around my timer interrput handler written in C - primarily for debug purposes to simplify debugging the state of registers and stack before the C code gets in and messes up the stack and state pushing all the jun...
Hi all,I am using Nucleo-L552 Evaluation board running , CMSIS_RTOSV2 (FreeRTOS), firmware STM32Cube FW_L5 V1.3.0. Debugging via built-in ST-Link. I have a Hard fault on HAL_GetTick() when running UART transmit on one of the threads. It debugs fine w...
Sir,I am using the STM32L432 for my project.How to get the PVD state ?I want to know the power voltage that is above the level or under the level.Thanks.void HAL_PWR_PVDCallback(void) { if ( __HAL_PWR_PVD_EXTI_GET_FLAG() ) { // TODO: get ...
I am not too familiar with embedded systems and just started learning about them. I have some parameters that lives in their own flash sector (16KB). They are stored as one long string ("PARAM1=X\r\nPARAM2=Y\r\n...." and so on). One of the parameters...
Hi everyone, I'm trying to use Input Capture with 1 Timer by using both edges option as external. I'm new at this microcontroller and I could not understand how to make it correctly with HAL library. Can anyone help me how to do?
Hi,I am using STM32H7's Timer 2 peripheral to generate a clock frequency ranging from 10Hz to 1MHz. To reconfigure the PWM to attain certain frequency, the PSC, ARR and CCR1 registers are modified.The sequence for modification is as follows: PWM_Star...
I'm having trouble understanding how the transfer complete interrupt is working.I have setup SPI using DMA to speed up data transfer to an LCD-display.The SPI clock is 18MHz, the System clock is 72MHz.From the book Mastering STM32 my understanding is...
My code works fine when STM32F303 ADC run at 8 bit, 3.6 MSPSWhen I trying to run ADC at maximum speed - 8bit 7.2 MSPS, DMA fails to get data. The bit OVR in ADC1_ISR is set and conversation stopped.If I read the ADC1_2_CDR register through the debugg...
I have configured PA2 as USART1 TX in STM32CubeMX, the code it generates looks correct:void MX_USART1_UART_Init(void) { /* USER CODE BEGIN USART1_Init 0 */ /* USER CODE END USART1_Init 0 */ LL_USART_InitTypeDef USART_InitStruct = {0}; ...
