STM32 MCUs Products

Could there anybody give me the FIT value of STM32F103RCT6TR at 50°C and 85°C with the linked information like activation energy and confidence level? If no, is there an online FIT calculator? Thanks Torsten Rehwald

Flashing STM32L476XX Discovery board

Hi,I am having a STM32L476XX discovery board. I am trying to use keil as IDE.I have successfully compiled the code, When I flash the code using the Load/Download(F8) code fails to execute.I did not get any error while flashing also.What can be the Is...

STM32F4 USART IRQ Problem

I am using USART2 (with IRQ) of STM32F4 for MIDI Receive (31250 bd, 8 Bit, 1Start/Stop Bit). A MIDI Message has normally 3 Bytes following directly on each other, which gives each Byte a duration of ca. 320us. In 1 of 10-30 events one Byte (always B...

How can I convert few mV AC to precise DC?

i want to convert (0mv - 1000mv AC)signal in to precise dc voltage for input to ADC of STM32 micro-controller for measure ac mains voltage suggest me any ic (single power supply +5V dc) or circuit diagram

I am using UART1 of STM32F407VE in interrupt method. I am checking loopback method.But I am losing some characters . I am using docklight serial monitor to send 20-30 set of characters.I need to store around 255 bytes of data to a buffer.

This is my interrupt handler...void USART1_IRQHandler(void)   { uint8_t data;   HAL_UART_IRQHandler(&huart1); __HAL_UART_CLEAR_FLAG(&huart1, UART_FLAG_RXNE); data = (uint8_t)(huart1.Instance->DR & (uint16_t)0x00FFU); HAL_UART_Transmit(&hua...

�?STM32H743】ADC gets WRONG values for zero voltage in ADC_DifferentialMode

Hi, I want to use the STM32H743 ADC in differential mode. At first, I tried the the example STM32Cube\Repository\STM32Cube_FW_H7_V1.3.2\Projects\STM32H743ZI-Nucleo\Examples\ADC\ADC_DifferentialMode and there is something wrong in testing zero vo...

FIFO question ?

Dear Members,How can I save FIFO ?I have a psedo code :for (i = 0; i < NUM_SAMPLES_TO_READ; i++) {Read FIFO_DATA;Save IR[15:8];Read FIFO_DATA;Save IR[7:0];Read FIFO_DATA;Save R[15:8];Read FIFO_DATA;Save R[7:0];}STOP;my code :   for(i=0;i<=number_samp...

What is the Best oscillator Value of HSE oscillator for STM32L476 such that the power consumption is minimum? How does the peripherals react to it?

I am using STM32L476.In it I am using MSI as a clock source, I want to switch to HSE as Clock Source, I want to know the best oscillator to use (4-48Hz) so that the power consumption is minimum, also I want to know if there would be any change in the...

Using SDRAM and STM32

Hello,My questions are as follows:1. Can I use DDR-SDRAM with FMC or should i use SDRAM only?2. Can I use two SDRAMs and control them with "Chip Select" pin? I want to use this SDRAM. This SDRAM is similar to used on the STM32F779EVAL board, but 512M...

Disable the IWDG when the MCU is stopped in debug mode in a STM32F0

Posted on November 02, 2017 at 09:19Hi all, In a STM32F0 I have configured the IWDG and every time that in debug mode I stop the MCU, then the watchtdog  active and the reset is on.I read the user Manual and some post seen in this community . I use ...
