I see that H723 and variants are coming.Any plan for Nucleo or discovery kit for these?

Trying to use SDIO interface on STM32F469I-Discovery Board and STM32CubeIDE always returning FR_DISK_ERR for both 1-bit and 4-bit SDIO modes

HI,I'm trying use SDIO interface on STM32F469I-Discovery board and I'm always getting FR_DISK_ERR for the command "f_open(&myfile,myPath,FA_CREATE_ALWAYS|FA_WRITE)" Same problem is observed with 1-bit and 4-bit SDIO mode. I have enabled "Use DMA te...

Problem with baud rate 19200 on STM32F0.

HelloI have the problem with USART baud rate in STM32F09x. I want to use baud rate: 9600, 19200, 38400, 57600, 115200bps with data length - 8 bits, parity and one stop bit. I can connect to the device at all speeds except 19200. Microcontroller uses ...

HAL API sets NVIC priority from 0 to 3 only whereas rM0376 suggests otherwise

I am using STM32L072hence referring to reference manual RM0376Page . 280 Table.53 suggests that priority can be from 0 till 38but when try HAL_NVIC_SetPriority(IRQn_Type IRQn, uint32_t PreemptPriority, uint32_t SubPriority)as per help above that f...

STM32H723/733, 725, 735, 730 VREFINT confusions

There are two points of confusions.1. VREFINT_CAL is a 12-bit precision valueUnlike predecessor of H7 family (H743, H7A3, etc.), the VREFINT_CAL value stored in VREFINT_CAL_ADDR is a 12-bit precision value stored in a 16-bit (8-bit x 2) location.For ...

CANtx Buffer, Not sending all CAN tx messages and skipping, any methods in dealing with the CANTxMail?

I'm currently using the stm32f413zh, and face perhaps a general problem where I'd like to send four CAN messages right after each other. If we refer to the image below, I have four "addtxCAN" commands below and only able to see the first three. When ...

Internal temperature reading and DAC output

I am trying to get the temp of the internal temp sensor.. I tested on both MB1367 demo board and my own board.I use jumper to connect JP8 pin2 and pin 3 to get Vref as 3.3V. I attached the cubmx and main file of my simple code. The issue is I always...

STM32G4 Timer Break On Exceptions

Hello,I would like to test the behaviour of STM32G4 MCU timers on exceptions. The SYSCFG register has several options for timer break. The HAL library provides the following macros to activate these options:__HAL_SYSCFG_BREAK_ECC_LOCK();__HAL_SYSCFG_...
