3. Getting started
The EVAL board uses Mini USB connecter to get power DC +5V, which is the hardware
system normal work voltage. A GD-Link on board is necessary in order to download and
debug programs. Select the correct boot mode and then power on, the LED3 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. During use, the following points should be noted:
1. If you use Keil uVision4 to open the project. In order to solve the "Device Missing (s)"
problem, you can install GigaDevice.GD32F3x0_DFP.3.0.0.pack.
2. If you use IAR to open the project, install IAR_GD32F3x0_ADDON_3.0.0.exe to load the
associated files.

5.1. GPIO_Running_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
GD32F310G-START board has one LED. The LED1 is controlled by GPIO. This demo will
show how to light the LED.
5.1.2. DEMO running result
Download the program <01_GPIO_Running_LED> to the EVAL board, LED1 will turn on and
off in sequence with interval of 1s, repeat the process.
5.2. GPIO_Key_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
GD32F310G-START board has two keys and one LED. The two keys are Reset key and User
key. The LED1 is controlled by GPIO.
This demo will show how to use the User key to control the LED1. When press down the User
Key, it will check the input value of the IO port. If the value is 1 and will wait for 50ms. Check
the input value of the IO port again. If the value is still 1, it indicates that the button is pressed
successfully and toggle LED1.
5.2.2. DEMO running result
Download the program <02_GPIO_Key_Polling_mode> to the EVAL board, the LED1 will
flash once for test and then turn on, press down the User Key, LED1 will be turned off. Press
down the User Key again, LED1 will be turned on.

5.3. EXTI_Key_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
GD32F310G-START board has two keys and one LED. The two keys are Reset key and User
key. The LED1 is controlled by GPIO.
This demo will show how to use the EXTI interrupt line to control the LED1.When press down
the User 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_EXTI_Key_Interrupt_mode> to the EVAL board, LED1 will flash
once for test and then turn on, press down the User Key, LED1 will be turned off. Press down
the User Key again, LED1 will be turned on.
5.4. TIMER_Key_EXTI
5.4.1. 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
Learn to use TIMER to generate PWM
GD32F310G-START board has two keys and one LED. The two keys are Reset key and User
key. The LED1 is controlled by GPIO.
This demo will show how to use the User Key and TIMER PWM to trigger EXTI interrupt
line to toggle the state of LED1. When press down the User Key, it will produce an
interrupt. In the corresponding interrupt service function, the demo will toggle LED1.
When connect PA6(TIMER2_CH0) and PA4 with DuPont line, EXTI interrupt occurs on
the falling edge of the PWM signal. In the corresponding interrupt service function, the
demo will toggle LED1.
