Clearing the SPI Buffer

Hi all, I'm working on a project where I am using an STM32F3 (master) to communicate with an STM32G0 (slave) using SPI with DMA. The G0 performs a task and can receive commands, and have it's "registers" (ie. state data) read out over the SPI. I want...

How to change MSI frequency on the fly ?

Hi, I am working on an STM32L476RCT6 and I use STM32CubeMX to configure the peripherals of the microcontroller.Currently the microcontroller runs on MSI, whose frequency is set at 8 MHz. The clock configuration is as follows :I want to use the USB in...

Mutli channel ADC with DMA. HAL_ADC_ConvCptlCallback doesn't get hit.

I'm using a STM32F411CE ("black pill") with STM32 Cube IDE and have been following this tutorial, except I'm using a different board and 5 ADC channels instead of 1. I have set them up as in the attached .ioc file. I would like to use a ping-pong buf...

STM32F107VC SPI Interrupt mode does not call HAL_SPI_TxRxCpltCallback

Dear allI have generated a test project via CubeMX, for STM32F107VC MCU for sending data as a MASTER SPI to a slave device (another STM32 device) by using Interrupt mode.They system is running FreeRTOS 10 (tick on systick) and HAL (tick on TIM7).TIM7...

STM32H735-DK reset

I have a demoboard STM32H735-DK. I develop a demo for my customer. All OK. But when I supply the card (with USB cable) the application-firmware doesn't run: I have to press the button reset for start it. Why? Thanks for your answer.
