STM32L451 UART circular DMA receptions not generating a full buffer (TC) interrrupt

Hi.I’m using CubeIDE, CubeMX and HAL to create an application for an STM32L451.I’ve setup USART1 to receive via DMA in circular mode and detect line idle, starting receptions with HAL_UARTEx_ReceiveToIdle_DMA(), and processing receptions in callback

Correction for STM32WB5MM-DK Board User Manual: PE3 at CN4 is actually PE4

HiI just noticed an error in the STM32WB5MM-DK User Manual V5 UM2825:In “Table 19. ARDUINO® connector pinout” there is the signal PE3 at pin 5 of the CN4 connector.The EXTI3_IRQHandler of my project and the Board Schematic V2 MB1292-D01 say otherwise

STM32CubeProgrammer issues with OCTOSPI on STM32U5G9NJH6Q

I discovered this issue while trying to program the Riverdi SM-RVT50HQSNWC01 using the STM32UG59. I spent days trying to figure out why the Riverdi demo in TouchGFX 4.26.1 was failing to program the external flash. It always failed when trying to e

I3C Controller Initialization Problem

Hello,I have a project that uses I3C to connect a Nucleo-C562RE with an STM32C542CCT6 MCU. The setup was working fine with HAL 2.0.0 but it does not work in 2.1.0. I generated the code with MX2 and I observed that it is identical to the code in the p

LPS22DF sensor freezes

Did anyone have issue with freezing LPS22DFsensor?Have it connected using 4 wire SPI at 3.3 and 3.3 Volts. It successfully starts and reads temperature and air pressure once and than stays at the same value with no updates until I reset power on it.
