User Guide
V2.0

Summary

GD32330G-START board uses GD32F330G8 as the main controller. As a complete development platform of GD32F3x0 powered by ARM® Cortex™-M4 core, the board supports the full range of peripherals. It uses a mini-USB interface 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.

Getting started

The START Board uses a mini-USB connector to get power, the hardware system power is +3.3V. A mini-USB cable is 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 the Keil versions and IAR versions of all projects. The Keil versions of the projects are created based on Keil MDK-ARM 4.74 uVision4. IAR versions 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 the  Project menu, select the Manage sub-menu, click on the “Version Migrate 5 Format…” menu, and the Keil uVision4 project will be converted to the 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 the 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_GD32F3x0_ADDON.2.0.0.exe to load the

Routine use guide

5.1. GPIO_Runing_Led
5.1.1. DEMO purpose

This Demo includes the following functions of GD32 MCU:

• Learn to use GPIO for controlling the LED
• Learn to use SysTick to generate a 1ms delay

GD32330G-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_Runing_Led> to the board, the state of LED1 is toggled every 1s.
5.2. GPIO_Key_Polling_mode
5.2.1. 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 SysTick to generate a 1ms delay

GD32330G-START board has two keys and one LED. The two keys are the Reset key and the User key. The LED1 is controlled by GPIO.
This demo will show how to use the User key to control the LED1. When pressing down the User Key, 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 lights the four 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 the test. Then press down the User Key, and LED1 will be turned on. Press down the User Key again, and LED1 will be turned off.
5.3. GPIO_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 an external interrupt

GD32330G-START board has two keys and one LED. The two keys are the Reset key and the User key. The LED1 is controlled by GPIO.
This demo will show how to use EXTI interrupt line to control the LED1. When pressing 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_GPIO_Key_Interrupt_mode> to the board, first of all, all the LEDs will be flashed once for test. Then press down the User Key, and LED1 will be turned on. Press down the User Key again, and LED1 will be turned off.
