How to calibrate RTC on STM32F411CEU6
Hello everyone! I have stm32f411ceu6 dev board, and I decided to use RTC. But it's going slower than time on reference clock. I use 32768 oscillator, which is soldered on the board. Can I calibrate this thing?

Resolved! STM32F401 and STM32U575 Pin compatibility QFN48 and LQFP48 package
Hi All,I wanted to move from STM32F401 to a ECC enabled MCU and came across the STM32U575/585 series. Is it possible to in place use the QFN48 package for stm32u575 in place of stm32f401?. The pinouts/ports/power pins all look to be the same. are the...
Resolved! STM32H7 SPI chip select intermittently delayed
I’m working on a project that uses an STM32H745IIK6. Occasionally, 32-bit SPI read data was invalid. This happened in about one out of every two hundred reads. To track down the cause, I added a few lines of code to toggle a GPIO pin as a scope trigg...
MX_I2C2_Init used but never define H7A3

STM32L476: MainApp code offset 0x08008000, flash/debug work but debug only did not
Using STM32CubeIDE (1.13.1) and STM32L476RG Nucleo board.The MainApp code has modified start address 0x08008000 via linker file and system_stm32l4xx.c file so VTOC point to interrupt vector from 0x08008000 with start code from 0x08008190. Under the d...
Creating a C++ Program to Update STM32F722 Firmware via USB DFU
I am currently working on a project where I need to create a C++ program for my PC that simplifies the firmware update process for an STM32F722 microcontroller. I have successfully placed the microcontroller in bootloader mode, which comes preloaded ...
Uart DMA does not receive after a while
Hello, I am doing UART communication with DMA in my project. When the communication first starts, there is no problem, but after about 10 minutes, the receive process ends. Can you check my codes?volatile uint8_t txdata[8];char rxdata[8]={'*','*','*'...
STM32L412 issues with RTC
Hello! I am using the RTC of a STM32L412 with 32kHz LSI to wake the MCU from STOP2 mode after a specified time in seconds. Now I´m having two issues:1) I cannot program the MCU using a ST-Link V2 with current Firmware, when the STOP2 mode is active. ...
50Hz sine wave generation in STM32
Hello team,We are looking to generate a sine function of 50 Hz frequency using the STM Cordic.Can you please share the theta range in this case. While we are giving 0 to 1 or 0 to 2pi (normal theta range), the resulting sine wave is not as per expect...
Can the STM32H7 transmit/receive data over SPI and UART while in sleep mode?
I'm fairly new to low-power and sleep-mode applications of STM32H7 microcontrollers. I've been trying to read through the documentation, but I'm having trouble getting a whole picture idea of how this works, and connecting all the information from th...
