STM32 MCUs Products

Is there a way to interface and communicate with GSM module SIM800L using X-CUBE-CELLULAR software expansion on STM32F boards(STM32F446RE) or any other option available?

SPI DMA master - slave communication issues, F722 and F765 SPI_FLAG_BSY and HAL_DMA_ERROR_FE errors (HAL)

Hi there!I have a project with one Master (F765) and three Slaves (F722), connected by different SPI channels for data exchange via DMA. Also slaves use additional Busy and DataReady signals for flow control and synchronization. IRQ handlers works on...

Modbus RTU crc calculation- STM32F407

Hi everybody,First, I'm sorry for my poor English.I'm using STM32F407VET6 and I want to calculate 16bit CRC of Modbus RTU. Can anybody help me how I can use hardware CRC of the STM32F407? Is it possible to use hardware crc for modbus rtu? Or should I...

Hi,Can someone has STM32F401 discovery board to verify the Accelerometer functionality please?​Actually I want to extend the accelerometer functionality for another application.But sadly the accelerometer LSM303DLHC is not working in new application....

STM32F429I-DISC1 I2C Communication with onboard ST MEMS Gyroscope

I am trying to retrieve data from the onboard ST MEMS gyroscope, but while setting up I2C I have been running into issues. At first I consulted the gyroscope data sheet to find the address associated with it, but both values (0x68 and 0x69) shifted t...

I am just learning this architecture, IDE, and re-learning C. I have tried programming an example of a I2C for a LCD display. It compiles fine, but does not write to the display. I suspect it has to to do with HAL. Where or to whom can I have look ove

I am using a NUCLEO-H723

Unable to adjust RTC or TAMP backup registers on STM32U585QIIbQ, any suggestions? I haven't seen any details in documentation as to why, and have been trying things for a few days.

I have tried the HAL without success - It seems to hard fault when initializing RTC.I have privilege disabled, and trust zone disabled,Unable to access any RTC or TAMP registers.Here is a minimal example of code, including the snippets of misc things...

Interrupt pin doesn't working STM32L053

Hi friends, I have STM32L053C8T6TR, where I use PPS pulse from GPS connected to PB8. I set this pin: #define GPS_PPS_Pin LL_GPIO_PIN_8 #define GPS_PPS_GPIO_Port GPIOB     void gps_pps_pin_init(void) {   LL_EXTI_InitTypeDef EXTI_InitStru...
