.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 ...

The debugger shows me variable differently from as i declared

I declare this two variable globallyuint8_t data_rcv_flg[1] = { 0 }; /* To avoid reuse of data */ uint8_t run[1] = { 0 }; I use this variable here:MODEM_ConfigTypeDef modem_cfg; modem_cfg.buff = data; modem_cfg.rcv_flag = data_rcv_flg;   PROTOCOL_Con...
