Example Description

This example shows how to use UART auto flow control function (Auto RTS and Auto CTS).

In this example, Main clock is from PLL clock and it is configured at 96MHz. The PLL clock is based on 8MHz HSE. APB1 and APB2 clock is from Main clock.

RTS: Output Signal, Modem Control Request To Send. If the output is low, it indicates that the UART is ready to receive data. CTS: Input Signal, Clear To Send Modem Status. If the input level is high, the next data transmission is blocked at the end of the current data transmission.

The UART1 is configured as follow:

  • BaudRate: 9600
  • Word Length: 8
  • Stop Bit: 1
  • No parity
  • Auto flow control enabled
  • FIFO is enabled
