Nucleo-H745ZI-Q Serial Comunication and monitoring.

My Nucelo have 4xUART and 4xUSART. How many UART/USART ports can i enable at the same time and how many if any can i monitor on my PC via ST-LINK. Arduino board is really simple you j ust need to chose serial monitor from ArduinoIDE. Is CubeIDE provi...

Error in smbus clock signal

Hi Team,I am using Smart battery in my product. While reading the battery voltage or current, that value was unexpected. while debugging the clock signal was not correct. In smbus line three devices were connected, Host(mcu (stm32h7)), Master(Battery...

.bin file is not updating (size in bytes) if I try to use example project of e X-NUCLEO-IHM15A1 dual brush DC motor driver expansion based on STSPIN840 for STM32F401RENucleo. but .elf is getting updated (in KB) when I try to build. Please help.

Run automatically a code of MCU when i connected to a battery only.

Hello, hope you are all well!I am new in this field. I am trying to do a project where I have to program a board.The board contains the following: a) a STM32L4 module and b) an external chip.The board that I am using for debugging is a Discovery boar...

heap allocation - the size of the RAM is smaller than expected.

Hello,I’m currently developping an image software on a nucleo h743zi2 with mbed.I have to deal with 10b VGA images coming from the DMA & DCMI interface. to store it, I need a RAM bigger than 640 x 480 x 2 bytes = 614.400 bytes.After looking at th spe...

has anyone ever made a STM32 project with an infrared sensor by using PWM on the transmitter pin. the result of my sensor isn't running

Hello. I am using STM32L476 nucleo board. I am facing problem in SPI communication.

I am trying to communicate with a peripheral device through SPI interface using the HAL SPI library functions. But the function is not working properly. It is getting stuck inside the HAL_Delay function. HAL_SPI_Transmit function just executes an emp...

How to re-enable the timer after a One pulse goes off (OPM)?

Hi guys I am using the stm32h753zi MCU and writing my own drivers to use the WS2812B led strip.It uses a PWM to determine how much of the RGB you want. I got the PWM part down and the OPM done, the problem is that I want to send let say a duty cycle ...
