1. Summary
GD32170C-START-V1.0 board uses GD32F170C8T6 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.

LEDs will be flashed once for test. Then press down the User Key, LED1 and LED2 will be
turned on. Press down the User Key again, LED1 and LED2 will be turned off.
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
GD32170C-START-V1.0 board has two keys and two LEDs. The two keys are Reset key and
User key. The LED1 and LED2 are controlled by GPIO.
This demo will show how to use the TIMER PWM to trigger EXTI interrupt to toggle the state
of LED2 and 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.
5.4.2. DEMO running result
Download the program < 04_TIMER_Key_EXTI > to the EVAL board, all the LEDs are
flashed once for test, press down the User Key, LED1 will be turned on. Press down the User
Key again, LED1 will be turned off. Connect PA6 (TIMER2_CH0) and PF7 with DuPont line.
The LED2 will be toggled every 500ms.
