3 Getting started
The EVAL board uses Mini USB connecter or DC-005 connector to get power DC +5V,
which is the hardware system normal work voltage. A J-Link tool or GD-Link on board is
necessary in order to download and debug programs. Select the correct boot mode and
then power on, the LEDPWR will turn on, which indicates that the power supply is OK.
There are Keil version and IAR version of all projects. Keil version of the projects are
created based on Keil MDK-ARM 4.74 uVision4. IAR version of the projects are created
based on IAR Embedded Workbench for ARM 7.40.2. In Firmware folder, Addon and
Software Pack are used to add the devices, peripherals and others to IDE. During use,
the following points should be noted:
1. If you use Keil uVision4 to open the project, install the GD32F4xx_Addon.1.0.0.exe
which is in \Library\Firmware to load the associated files.
2. If you use Keil uVision5 to open the project, there are two ways to solve the "Device
Missing (s)" problem. One is to install GigaDevice.GD32F4xx_DFP.1.0.0.pack which is
in \Library\Firmware. In Project menu, select the Manage sub menu, click on the
“Version Migrate 5 Format...” menu, the Keil uVision4 project will be converted to Keil
uVision5 project. Then add “C:\Keil_v5\ARM\Pack\ARM\CMSIS\4.2.0\CMSIS\Include” to
C/C++ in Option for Target. The other is to install Addon directly. Select the installation
directory of Keil uVision5 software, such as C:\Keil_v5, in Destination Folder of Folder
Selection. Select the corresponding device in Device of Option for Target and add
“C:\Keil_v5\ARM\Pack\ARM\CMSIS\4.2.0\CMSIS\Include” to C/C++ in Option for Target.
3. If you use IAR to open the project, install IAR_GD32F4xx_Addon.exe which is in
\Library\Firmware to load the associated files.

5.1 GPIO_Runing_Led
5.1.1 DEMO Purpose
This demo includes the following functions of GD32 MCU:
Learn to use GPIO control the LED
Learn to use SysTick to generate 1ms delay
GD32450Z-EVAL board has three LEDs. The LED1, LED2 and LED3 are controlled by
GPIO. This demo will show how to light the LEDs.
5.1.2 DEMO Running Result
Download the program <01_GPIO_Runing_Led> to the EVAL board, LED1, LED2,
LED3 will turn on in sequence with interval of 200ms, and turn off together, 200ms later,
repeat the process.

5.2 GPIO_Keyboard_Polling_mode
5.2.1 DEMO Purpose
This demo includes the following functions of GD32 MCU:
Learn to use GPIO control the LED and the KEY
Learn to use SysTick to generate 1ms delay
GD32450Z-EVAL board has four keys and three LEDs. The four keys are Reset key,
Tamper key, Wakeup key and User key. The LED1, LED2 and LED3 are controlled by
GPIO.
This demo will show how to use the Tamper key to control the LED1.When press down
the Tamper Key, it will check the input value of the IO port. If the value is 0 and will wait
for 100ms.Check the input value of the IO port again. If the value still is 0, it indicates
that the button is pressed successfully and toggle LED1.
5.2.2 DEMO Running Result
Download the program <02_GPIO_KeyBoard_Polling_mode> to the EVAL board, press
down the Tamper Key, LED1 will be turned on. Press down the Tamper Key again, LED1
will be turned off.
5.3 GPIO_KeyBoard_Interrupt_mode
5.3.1 DEMO Purpose
This demo includes the following functions of GD32 MCU:
Learn to use GPIO control the LED and the KEY
Learn to use EXTI to generate external interrupt
GD32450Z-EVAL board has four keys and three LEDs. The four keys are Reset key,
Tamper key, Wakeup key and User key. The LED1, LED2 and LED3 are controlled by
GPIO.
This demo will show how to use the EXTI interrupt line to control the LED1.When press
down the Tamper Key, it will produce an interrupt. In the interrupt service function, the
demo will toggle LED1.

5.3.2 DEMO Running Result
Download the program <03_GPIO_KeyBoard_Interrupt_mode> to the EVAL board,
Press down the Tamper Key, LED1 will be turned on. Press down the Tamper Key again,
LED1 will be turned off.
5.4 USART_Printf
5.4.1 DEMO Purpose
This demo includes the following functions of GD32 MCU:
Learn to use GPIO control the LED
Learn to retarget the C library printf function to the USART
5.4.2 DEMO Running Result
Download the program < 04_USART_Printf > to the EVAL board, jump the JP13 to
USART with the jumper cap and connect serial cable to EVAL_COM1. This
implementation outputs “USART printf example: please press the Tamper key” on the
HyperTerminal using EVAL_COM1. Press the Tamper key, serial port will output “USART
printf example”.
The output information via the serial port is as following.
5.5 USART_Echo_Interrupt_mode
5.5.1 DEMO Purpose
This demo includes the following functions of GD32 MCU:
Learn to use the USART transmit and receive interrupts to communicate with the
serial terminal tool
5.5.2 DEMO Running Result

the JP13 to USART with the jumper cap and connect serial cable to EVAL_COM1. Firstly,
all the LEDs are turned on and off for test. Then, the EVAL_COM1 sends the tx_buffer
array (from 0x00 to 0xFF) to the serial terminal tool supporting hex format
communication and waits for receiving data of BUFFER_SIZE bytes from the serial
terminal. The data MCU have received is stored in the rx_buffer array. After that,
compare tx_buffer with rx_buffer. If tx_buffer is same with rx_buffer, LED1, LED2, LED3
flash by turns. Otherwise, LED1, LED2, LED3 toggle together.
The output information via the serial port is as following.
5.6 USART_DMA
5.6.1 DEMO Purpose
This demo includes the following functions of GD32 MCU:
Learn to use the USART transmit and receive data using DMA
5.6.2 DEMO Running Result
Download the program < 06_USART_DMA > to the EVAL board, jump the JP13 to
USART with the jumper cap and connect serial cable to EVAL_COM1. Firstly, all the
LEDs are turned on and off for test. Then, the EVAL_COM1 sends the tx_buffer array
(from 0x00 to 0xFF) to the serial terminal tool supporting hex format communication and
waits for receiving data of the same bytes as tx_buffer from the serial terminal. The data
MCU have received is stored in the rx_buffer array. After that, compare tx_buffer with
rx_buffer. If tx_buffer is same with rx_buffer, LED1, LED2, LED3 flash by turns.
Otherwise, LED1, LED2, LED3 toggle together.
