uart_polling

This is an example of UART polling

• Select the UART TX/RX pins

  // in main.c
  #define CONFIG_UART_IO_TX_PORT		GPIOA
  #define CONFIG_UART_IO_TX_PIN		GPIO_Pin_01
  #define CONFIG_UART_IO_TX_AF_MODE	GPIO_AF_1
  #define CONFIG_UART_IO_RX_PORT		GPIOA
  #define CONFIG_UART_IO_RX_PIN		GPIO_Pin_00
  #define CONFIG_UART_IO_RX_AF_MODE	GPIO_AF_1
  

• Configure the parameters related to UART

• It can be modified according to the requirements

  // in main.c
  #define CONFIG_BAUD_RATE_VALUE  38400
  UART_WordLength_8b	//Data bit 8
  UART_StopBits_1		//Stop bit 1
  UART_Parity_No		//No check bit
  UART_Mode_TxRx	//Transmit-Receive Mode
  

Log

Use serial port with baudrate 38400, 8bit, no parity check

• PC sends 1~255 to PEC930
• PEC930 receives and sends back data
