Resolved! CMSIS-RTOS2 freezes on external interrupt

Hi,I'm trying to use an interrupt with CMSIS_RTOS2. The user button is configured to use as an interrupt source:When I push the button, the system freezes. I suspect the interrupt flag doesn't get cleared but I have no idea why.There is nothing (yet)...

Resolved! STM32U5A5: AZURE RTOS and 1ms ticks - how to set?

I am confused: I want to have 1ms AZURE RTOS tick timer - but no idea how to set.What I see:AZURE RTOS defines 10ms tick timer (UX_PERIOD_RATE, TX_TIMER_TICK_PER_SECOND)I see as well, when using tx_thread_sleep(1000); - it sleeps 10 second (not 1) - ...

[BUG] STM32 HAL driver lock mechanism is not interrupt safe

STM32 HAL driver library is full of flawed and sub-optimal constructs. The most common one, which impacts almost all drivers, is the lock mechanism. It's a bad and limiting design and getting rid of it requires a major rewrite, but the worst fact is ...

ethernet interrupt not working

I send an ethernet packet to MAC address 00:80:E1:00:00:00 but no interrupt occurs in STMEnabled Ethernet interrupts in CubeMX.What could be wrong?Code:/* USER CODE BEGIN Header */ /** ***************************************************************...

Resolved! STM32G0 USART3 and USART4 share an interrupt. How to deal with it?

void USART3_IRQHandler(void) is incorrect, since USARTs 3/4 share the interrupt, it doesn't compile. What replaces 'USART3' in the interrupt handler?NVIC_ClearPendingIRQ(USART3_IRQn); is incorrect since USART3 3/4 share the interrupt. What replaces '...

What woul be the best way to read ADC in an RTOS?

I'd like to get ADC readings, implemented with DMA while running in an RTOS.The problem is that the ADC with DMA interrupts the RTOS... don't know what could be the cause maybe interrupts conflicting?

Resolved! The callback function HAL_DAC_ConvCpltCallbackCh1(DAC_HandleTypeDef* hdac) with STM32U575CGU6 doesn't work

Could someone assist and clarify how to configure GPDMA for DAC for use the callback function HAL_DAC_ConvCpltCallbackCh1(DAC_HandleTypeDef* hdac) with STM32U575CGU6. I caught:/* Data Transfer Error Interrupt management */ if ((__HAL_DMA_GET_FLAG(hdm...

Everything works great in the enumeration, my device is correctly recognized by the host (Windows PC) as a mouse. I've chose to use an IN endpoint in interrupt mode to send the report to the host.
