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...
My STM32U031R8T6U (CPU: UID=0x20353953_39365013_0030007C Lot#=59S96P Wafer#=19 X=48 Y=124 FLASH=64KB) has 0xFFFF under VREFINT_CAL_ADDR - the Vrefint calibration data are absent.C code:printf("\r\n *VREFINT_CAL_ADDR=%u", *VREFINT_CAL_ADDR);Output:*VR...
Hello.STM32G431CBT6Is it possible to route the output from the comparator to the input of the Timer input? The reference manual says that this is possible, but there is no description. And in the comparator register there are no options for choosing ...
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...

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.
