Using Segger Jlink pins as GPIO's

I am developing a project that has M7 processor. I want to use Segger Jlink pin which is JDTI as GPIO.I want to keep it low until I set it. But, while flashing the code to my MCU, JDTI pin becomes high until passing the hal_initialize() function. So ...

Interrupt based LPUART with BLE application.

Hi I'm working with STM32WB5MMG-dk. The purpose is to develop BLE Gateway. The module has a custom GATT svc with 4 GATT char svc which sends and receive bytes, this data is been provided by MSP430 to STM32WB5 vice versa. So MSP430 acts as master whe...

STM32H7 SPI DMA is not working, HAL_SPI_STATE_BUSY_TX_RX state. Cache and MPU are disabled.

I am trying to use SPI and DMA in a STM32H7, but it is not worling. The spi handler goes to "HAL_SPI_STATE_BUSY_TX_RX" state as soon as i call the function "HAL_SPI_TransmitReceive_DMA" and it does not do anything, it does not even generate the clock...

Did anyone managed to read CANBUS without canbus peripheral? (softcanbus)

Is there any way for chips without the Canbus peripheral to read canbus?No external chips allowedMaybe uart or bitbanging gpios?

I want to initializ the ADC I have 3 different pins in STM32L476 and I use 3 ADC for each pin. I work in polling mode (without interrupt and without DMA) but I don't understand what is rank option? please could you give me an explanatio about this Parmer

How to setup PMA buffers for isochronous USB transactions

Hello, I've been trying to port the X-CUBE-USB-AUDIO library onto a STM32G0B1RE nucleo board. Right now, I'm struggling with the configuration of PMA buffers. My configuration right now : HAL_PCDEx_PMAConfig((PCD_HandleTypeDef*)pdev->pData, 0x00,...
