Hello, ST experts HAL_UARTEx_ReceiveToIdle_DMA works well in our project, it can get idle interrupt or uart data stream interrupt. But when STM32's partner power down and up again, I think that means UART_RX line to STM32 goes low during this period,...
I traditionally use a volatile type for my schedulers. Very simple like so volatile uint8_t myflag; uint8_t ticks; void Func(void){ ++ticks; if(!(ticks % 5)){ myflag = true; } } void User(void){ if(myflag) { myflag = false; //DO ...
I am using TIM2 to create PWMs for LEDs. When I enter STOP mode I expect the PWM to stop. Yet it does not. From the manual TIM do not have wakeup capability from stop mode. So they should not be requesting the HSI to operate.What could possibly cause...
I have 2 STM32F407 Discovery boards sending data back and forth to each other using usart2. Usart3 on one is just a monitor so I can see the output on a USB comm port. I'm using DMA on the receive for both and the HAL_UART_RxCpltCallback for both jus...
Hi, my current issue is that after implement Self test library for a stm32h5 the basic things like STL_SCH_Init() works fine but when i try to run the flash test the STL_SCH_ConfigureFlash fails, the status says STL_ERROR.How i run the test:I define ...
I am trying to create a project with FreeRTOS using CMSIS RTOS V2 without configuring it in the ioc file. I am trying to turn ON/OFF the LED using thread and timer. I can build and run the same project if I configure the freeRTOS in STM32CubeMX. Bu...
I'm currently using a STM32L433RCT3 and the L4 HAL library. My goal was to read back a configured RTC alarm, increment it, and restart the alarm. I created a:RTC_AlarmTypeDef sAlarm;I read back the RTC alarm using,HAL_RTC_GetAlarm(&hrtc,&sAlarm,RTC_A...
(found using STM32H723 NUCLEO board) Hi,When trying to implement a USG OTG application, where the USB port is required to switch backwards and forwards many times between device and host mode, there appears to be an error in the USBH_DeInit function ...
Hi!with cube IDE i'm trying to develop a USB device with 3 classes using a STM32H523 with USBX and threadX.If i select USB HID,USB MSC and USB ACM (virtual com port) the code is succesfully generated but if i close and reopen the .ioc GUI i have thi...
There seems to be a bug when using the USBX hub class. Sometimes it works, but most often it does not. The problem appears to be with file: ux_host_stack_enum_thread_entry.c. The code: VOID _ux_host_stack_enum_thread_entry(ULONG input) { UX...
