How do I process just UART RX interrupt events while using HAL_UART_Transmit_DMA

2021-09-21
Hi, I am working with F413 and I am using USART3 to receive and trasmit data over UART. As I need to receive unknow size of data I wrote my own interrupt handler for RX. However I would like to transmit data out with a help of DMA. If I call regular ...

STM32F413 flash erase doesn't work first time

2021-08-20
Hi,I am using STM32F413 Nucleo board. I am using MDK5 IDE and HAL libraries. I made an example for reading/writing internal flash based upon a cube project. The idea is to erase interal flash and then to write some data to it. I alreay did some simil...

Serial wire output on STM32L471ZGTx is not working - it hangs

2019-10-09
I am using MDK5 (5.22) with STM32CubeMX (4.26.1). I generate blank project within CubeMX for STM32L471ZGTx (144pin MCU). Clock configuration uses internal HSI and LSI and it's set to 16MHz. For testing purposes I configured clocks so all other clocks...

What is causing corrupted data when communicating with MPU6050 with DMA?

2019-02-22
Hi,I am using STM32F101VD to communicate via I2C with MPU6050 IMU device. Data transfer (reading and writing) is done using DMA. Additionally I connected one of my ST32's GPIO (configured as EXTI - Rising IT) to MPU's INT pin. I am using HAL librarie...

PC sends URB_FUNCTION_GET_DESCRIPTOR_FROM_DEVICE to composite hid device every 5 seconds

2018-09-07
I am not sure if this is STM32 related question but I noticed one strange behaviour while using STM32 devices with USB composite device and composite device only.So my device is composite device with three different interfaces (HID). I am transfering...
