Calling osDelay after osMailGet result in the micro stuck - using freeRTOS with CMSIS API

I'm working on a project using a STM32F446 with a boilerplate created with STM32CubeMX (for peripherals initialization and middleware like the FreeRTOS with the CMSIS-V1 interface). I have two threads which communicate using mailboxes but I encounter...

HAL_Delay problem!!!!!

Hello everyone!!!I get a problem with HAL_Delay function. When I use STM32CubeMX creat my simple project (blink a led with STM32F4 Discovery Kit) everything is OK with HAL_Delay() function.But when I creat a same project without using STM32CubeMX, HA...

CubeHAL I2C slave pulls down clock line and let it not go. Who knows what I can do when wanting to enable clock stretching.

Hi, I have problem with I2C. I use NUCLO446RE as a slave. STM32Cube FW_F4 V1.24.0 or 24.1. Both versions have the problem. I using also Atollic True Studio for STM32 or STM32CubeIDE 1.0.0. The problem occures with both platforms.When the master reque...

Anybody having success using HNP on USB OTG for STM32 MCU's?

Poor H7 Ethernet Rx Descriptor DMA handler implementation.

Took me quite a while to work through this lot, identifying what was actually going on, but here's a heads up for anyone else. The symptoms I was seeing were TCP failures in high traffic conditions (~ 0.2ms per rx). In particular, accessing port 80 /...

changing timer output polarity fail in toggle mode

I use the STM32G0 Timer2 to generate phase controlled signals. For negative phases the output needs to be toggled; After reset the state is always correct, but during runtime the OC polarity is not set correctly.Here is my function. Can someone told ...

USB Another OUT Endpoint

Hi,For my application i need to add just one more OUT endpoint to my USB Device. I am using nucleo f303re development board. I configured a CDC project from cubemx and made it a libusb project following stm training about usb but now i need to get 12...

HAL bug: HAL_TIM_PWM_Stop() function stops timer even when another channel is configured for input capture?

Hi,I'm on a L011 device with the following configuration for timer 2:Channel 1 is in input capture mode, rising edge. The timer itself is in auto-reset mode, on each rising edge on channel 1 the timer count is copied to the CCrx register and the time...
