Can't change SYSCLK in UART HyperTerminal example
When I create the UART_HyperTerminal_IT project in STM32Cube, SYSCLK's source is assigned to PLLCLK: RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_HSI; RCC_OscInitStruct.HSIState = RCC_HSI_ON; RCC_OscInitStruct.HSICalibrationValue = RCC_HS...
