Hi ,I'm using STM32F4x9 eval board with STM32Cube v1.24 library on USB device parctice.Refer to CDC example, a new SCAN device class was created and enumerated succcess.Sending data from PC host site (Bulk Out) can success to get in device (STM32 - v...
In the sample code, STM uses "HAL_GPIO_EXTI_Callback" to handle interrupt from a push button, but in class I learnt that we need to use the IRQHandler to handle the interrupt. When to use "HAL_GPIO_EXTI_Callback" and "HAL_GPIO_EXTI_IRQHandler" to han...
Hello,I have been having problems with my debugger losing connection when i set the CM7 of my STM32H745 into CSleep mode. I have the DBGMCU flags set to enable debugging in low power, but I assumed I was still doing something incorrect with the domai...
Hi, I'm using a STM32F429 with usb host connected to FS.Using the official USB MSC Host library from ST (1.24.1 latest one) I have a slow recognition when I insert a USB stick.The callback USBH_UserProcess with HOST_USER_CLASS_ACTIVE event, so after ...
Changing HAL SysTic from default timer1 to timer15 or timer16 in CubeMx introduced a problem in the code generator. I am using timer1 in my application, and noticed an unexpected interrupt at startup, and it looks like the Systic interrupt fires bef...
Good morning everyone,I was trying to establish communication via UART1 - UART2 - SPI1, everything is fine until i use "HAL_SPI_TransmitReceive(...)" and suddenly UART1 and UART2 are locked (i can visualize both those "UART_HandleTypeDef" in my Expre...
Hi All,I`m trying to build a project using STM32CubeMX with FreeRTOS and have FatFS for my own Board.And when I execute the code,it can {f_mount} really well but till {f_opendir} it come out the FR_INT_ERR.I have a question about if I use the FreeR...
