STM32 MCUs Products

Is it possible to record a video at the frame rate of 24 fps by using STM32F407VG on an external sd card?

STM32F105 CAN Bus unable to Init and/or Start. INAK bit not cleared. [SOLVED]

Hi all,I'm hoping you're able to help me with a problem I'm having when trying to enable CAN on the STM32F105.OverviewBit of an overview first for context. The idea behind the project is to enable both CAN buses on the MCU so that they're able to tra...

STMCUBEIDE - STM32L010 ROM(Flash) size exceeding

I am using STMCUBEIDE there i was using optimization level as "optimize for debug". there i used a local variable as uint8_t and i am incrementing its counts then memory exceeded to 85%. if i removed increment then only 37% flash memory occupied.

Peripheral current/power consumption data for STM32L476RG

Dear community,I am planning on using the STM32L476RG for a project. That project is a low power application, so the current consumption is really important to this project. However I cannot find any reliable source for the current consumption of the...

Choosing the right BLE + Cortex M0 module for smartwatch / IPC architecture

Hello all, I have started a rather ambitious project. I want to create a good smart watch. I have stm32l4r9 discovery board. My idea is to test how discovery board integrated Cortex M4 MCU can be integrated with separate BLE module, which comes with ...

directly read register status instead of HAL_GPIO_Readpin();

i am trying to bit bang 14 bits grey code. my output is not steadyuint16_t readbits(uint16_t dataPin, uint16_t clockPin) { uint16_t value =0;  for (int i = 0; i <14; ++i) {   value <<= 1;  HAL_GPIO_WritePin(GPIOC, clockPin, GPIO_PIN_RESET);  delay_...

Is there any instructions from STM on how to implement CMD53 in the SDIO interface for STM32H747?

I try to interface Cypress 4343W Wi-Fi module with STM32H747. i managed to port WICED SDK in STM32Cube IDE but when i start to send data using CMD53 i have problems that the DPSM always active which means from my understanding that the transmission s...

BRR of STM32F401RCT6 changed when hot swapping

When the USART is  hot swapping，some datas will occur on TX RX pin；and the value of BRR register will be changed;the picture 1 shows the BRR before  hot swapping;and the picture 2 shows the BRR after  hot swapping. Why this question happens?And what...

SPI1_NSS conflicts with PA15 in STM32F103

Hi,According to datasheet, The main function of PA15 is JTDI, so I disabled JTAG and config that pin in AF_PP mode.Then if I don't initialize SPI1, I can control PA15 as GPIO. But if I initialize SPI1, this pin will hold high. Since SPI1 has occupied...
