Low Power UART

What is the difference between LPUART and UART?. As far as i read there is no difference to use LPUART and normal one(except power consumption ofc). If I change my UART channel to LPUART, will be any difference? Will be the LP ones DMA usage differ ...

How to setting timeout of uart intterupt STM32F103?

STM32作为微控制器这一核心功能在设计�?生产当中所�?�循的国际标准�?行业标准或者�?业标准是什么

Hi. I want to send an "int" with the HAL_UART_Transmit method. But the strange shapes that I added appear in the picture. Why could it be?

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?
