Hello, i'm wondering if it is possible to copy data from RAM to flash using DMA after unlocking the FLASH memory static const uint32_t src[4] ={80,20,30}; static uint32_t dst = 0x080E0000; __HAL_RCC_DMA1_CLK_ENABLE(); dma_handler.Instance = DMA1...
I want to use input capture mode in my stm32l432kc nucleo-32 board to measure the length of a signal from a sensor of mine. I have set it up the following way:int main(void) { // ... MX_USART2_UART_Init(); MX_TIM16_Init(); HAL_TIM_IC_Start_IT...
Hi. First time using this forum.I'm using an STM32F103C8 (genuine, not bluepill clone).I've easily used DMA to take sensor data and store it in a buffer, this has worked without issue (see below): void HAL_GPIO_EXTI_Callback(uint16_t GPIO_Pin) { if ...
Hi. I discovered an issue on UM3292 while trying to get PCF8574 I2C LCD module to work with my STM32U083C-DK. On page 22, it is stated that D14 is connected to PB9. However, it is actually connected to PB7. I have the MB1933C version. When I replaced...
I have a Beaglebone Computer configured as SPI Masted, and an STM32F446 configured as SPI Slave. I am simply sending 'HelloWorld' from the Beaglebone to the STM32, and trying to send 'ABCDEFG!' from the STM32 to the Beaglebone. The STM32 receives the...
I've wrote a code without using Hal to produce a signal on the scope but i'm not getting any signal on my pin.This is on a NUCLEO F401RE. Using TIMER3_CHANNEL1 and GPIOB for my Alternate function. #include <stdint.h>#include "stm32f4xx.h"#include "st...
STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
I tried configuring PC8 for TIM3_CH3 to generate a PWM signal by using DMA stream. But im not seeing any signal on the line. The same is tried by configuring TIM3_CH4 on PB1 and this works. Please help me understanding what can be going wrong.
Hey guys, I need your help:I want to use the STM32F103C8T6 board.The microcontroller will receive an external 8 MHz clock (from a source other than the system clock).I want the microcontroller to count to 8, and for 2 of those counts, one of the outp...
Sorry for my 3rd XIP post on this board, but the more I learn about this process, the more questions I have. Going through the XIP template code, I think I have a decent understanding of what it does. 1. Set up the XSPI Peripherals, one NOR Flash and...
