This example describes how to receive interrupts using USART.
In this example, Main clock is from PLL clock and it is configured at 96MHz. The PLL clock is based on 8MHz HSE. APB1 clock is from Main clock, APB2 clock is the 2 frequency division of the Main clock.
This example enables interrupts to be received and idle, and sends a prompt message using USART at the start of the run. Then use PC serial port tool to send data to the development board, the development board will receive a frame of complete data will print back through the serial port. The serial port interrupts data and uses idle interrupts to determine whether a complete frame of data has been received
USART1 configuration is as follows:
In order to make the program work, you must do the following :
Run the example
