STM32 MCUs Products

We interfaced sd card on SDIO lines in 4 bit mode. While recording and playing audio files,we observed "ti tik tik" noise in the line. We are using external codec on i2s line for recording and playing. Kindly let us know how to resolve this issue,

ESP8266 node MCU GPIO control using goggle home and alexa how can i do this?

i want to make smart home project which includes-support goggle home mini & alexa & mobile app-1 fan speed control (ac voltage control)-dimmer(ac voltage control)-lights (on-off)how can i add support for both google & alexa?i found some resources but...

How can we get SDMMC working on STM32H743?

We have a working design in an STM32F745 device that talks to an eMMC device over SDMMC.  We ported the design over to an STM32H743 device, using CubeMX to configure the device to match the F7, and the SDMMC interface doesn't work.  We've gone throug...

Cannot flash STM32F103C8T6

Hello together, I am beginner with STM32-controllers and I have started reading the tutorial book "Beginning STM32" from Warren Gay.I ordered three STM32F103C8T6 platines and I have also three ST-Link V2 program/debug adapter, but only with one adapt...

What does happen in STM32F4 if I configure an I/O as analog, but it is not an analog one? I mean, smith trigger and output buffer are disabled as well as pu and pd?

Wake up MCU by CANbus interruptions from sleep mode (STM32L4)

Hello,I am working on power management and I put MCU in sleep mode (no low-power), but it doesn't wake up when it receives a CAN frame, it stays in sleep mode. I would like any CAN frame to wake up the MCU.To switch to sleep mode I use :HAL_PWR_Ent...

STM32F103C8T6 CAN receive interrupt not firing

Hi, I'm using an STM32F103C8T6 MCU with SN65HVD230 CAN transceiver to read can data. 500bps.Bus is healthy, terminated and HAL initializes OK, but the receive interrupt never fires.CAN_HandleTypeDef hcan;   CAN_FilterTypeDef sFilterConfig; CAN_TxHead...

How to configure CAN in STM32F103 using CMSIS?

Hi everyone! I use the STM32F103 microcontroller to work with the CAN bus. I work in the Keil v5 environment and use the CMSIS library (I took the source files for my MCU from CubeMX). However, during debug, when I send the first data frame, I get th...

Maintaining ADC operation while dynamically clock switching on STM32L4

Hi all,I am wondering whether it is possible to maintaining ADC(+DMA1 on AHB1) operation while clock switching on STM32L4. I am clocking the STM32L4 via HSE+PLL and the ADC from the PLLSAI1 (set to 40MHz).Is it remotely possible to switch from HSE+PL...
