5.6.

USART_DMA

5.6.1.

DEMO Purpose

This Demo includes the following functions of GD32 MCU:



Learn to use the

COM

transmit and receive using DMA

5.6.2.

DEMO Running Result

Jump JP13 to USART, then download the program < 06_USART_DMA > to the EVAL

board and run. Firstly, all the LEDs are turned on and off for test.

Then, the

COM

sends

the tx_buffer array to the hyperterminal and waits for receiving data from the

hyperterminal that you must send. The string that you have sent is stored in the

rx_buffer array. The receive buffer have a BUFFER_SIZE bytes as maximum. After that,

compare tx_buffer with rx_buffer. If tx_buffer is same with rx_buffer, LED1 and LED2

are turned on, LED3 and LED4 are turned off. Otherwise, LED1 and LED2 are turned off,

LED3 and LED4 are turned on.

The information via a serial port output as following:

5.7.

RS485_Test

5.7.1.

DEMO Purpose

This Demo includes the following functions of GD32 MCU:



Learn to use the USART RS485
