1. Summary
GD32130G-START-V1.1 board uses GD32F130G8U6 as the main controller. As a complete
development platform of GD32F1x0 powered by ARM® Cortex™-M3 core, the board
supports full range of peripherals. It uses mini-USB interface to supply 3.3V power. SWD,
Reset, Boot, User button key, LED and Extension Pin are also included. This document
details its hardware schematic and the relevant applications.

3. Getting started
The START Board uses mini-USB connecter to get power, the hardware system power is
+3.3V. A mini-USB cable are necessary to down programs. Select the correct boot mode and
then power on, the LED3 will turn on, which indicates the power supply is ready.
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, install the GD32F1x0_AddOn.3.2.0.exe 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.GD32F1x0_DFP.3.2.0.pack. 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_GD32F1x0_ADDON.3.2.0.exe to load the
associated files.

every 200ms.
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
GD32130G-START-V1.1 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, wait for 50ms. Then
check the input value of the IO port again. If the value is still 1, indicates that the button is
pressed down successfully, and light the LED1.
5.2.2. DEMO running Result
Download the program <02_GPIO_Key_Polling_mode> to the board, first of all, the LED1
will be flashed once for test. Then press down the User Key, LED1 will be turned on. Press
down the User Key again, LED1 will be turned off.
5.3. EXTI_Key_Interrupt_mode
