1. Summary

GD32350G-START board uses GD32F350G8 as the main controller. As a complete

development platform of GD32F3x0 powered by ARM® Cortex™-M4 core, the board

supports full range of peripherals. It uses mini-USB interface or AC/DC adapter to supply 5V

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 or AC/DC adapter 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 GD32F3x0_AddOn.2.0.0.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.GD32F3x0_DFP.2.0.0.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

User Guide

GD32350G-START

9 /13

Learn to use SysTick to generate 1ms delay

GD32350G-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, 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, all the LEDs

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

5.3.1. DEMO purpose

This Demo includes the following functions of GD32 MCU:

Learn to use GPIO to control the LED and the KEY

Learn to use EXTI to generate external interrupt

GD32350G-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 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 board, first of all, all the

LEDs 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.
