3. Getting started
The START board uses GD-Link Mini USB connecter to get power DC +5V, which is the
hardware system normal work voltage. AGD-Link on board is necessary in order to download
and debug programs. Select the correct boot mode and then power on, the LEDPWR will turn
on, which indicates 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 5.26 uVision5. IAR version of the projects are created based on IAR
Embedded Workbench for ARM 8.32.1. During use, the following points should be noted:
1. If you use Keil uVision5 to open the project. In order to solve the "Device Missing (s)"
problem, you can install GigaDevice.GD32E50x_DFP.1.3.0.pack.
2. If you use IAR to open the project, install IAR_GD32F50x_ADDON_1.3.0.exe to load the
associated files.

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
GD32E507R-START-V1.1 board has 2 keys and four LEDs. The keys are User Key and Reset
Key. The LEDs are controlled by GPIO.
This demo will show how to use the User Key to control the LED2. 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 100ms. Check
the input value of the IO port again. If the value still is 1, it indicates that the button is pressed
successfully and toggle LED2.
5.2.2. DEMO running result
Download the program < 02_GPIO_Key_Polling_mode > to the START board, press down
the User Key, LED2 will be turned on. Press down the User Key again, LED2 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 control the LED and the KEY
Learn to use EXTI to generate external interrupt
GD32E507R-START-V1.1 board has 2 keys and four LEDs. The keys are User Key and Reset
Key. The LEDs are controlled by GPIO.
This demo will show how to use the EXTI interrupt line to control the LED2. When press down
the User Key, it will produce an interrupt. In the interrupt service function, the demo will toggle
LED2.
5.3.2. DEMO running result
Download the program < 03_EXTI_Key_Interrupt_mode > to the START board, LED2 is
turned on and off for test. When press down the User Key, LED2 will be turned on. Press
down the User Key again, LED2 will be turned off.
5.4. USART_HyperTerminal_Interrupt
5.4.1. DEMO purpose
This demo includes the following functions of GD32 MCU:
Learn to use the USART transmit and receive interrupts to communicate with the
HyperTerminal.
5.4.2. DEMO running result
Download the program <04_USART_HyperTerminal_Interrupt> to the START board, connect
serial cable to UART. Firstly, all the LEDs are turned on and off for test. Then, the UART4
sends the tx_buffer array (from 0x00 to 0xFF) to the hyperterminal and waits for receiving
data from the hyperterminal that you must send. The string that you have sent is stored in the
rx_buffer array. The receive buffer have a BUFFER_SIZE bytes as maximum. After that,
compare tx_buffer with rx_buffer. If tx_buffer is same with rx_buffer, LED1, LED2, LED3,
LED4 flash by turns. Otherwise, LED1, LED2, LED3, LED4 toggle together.
The output information via the HyperTerminal is as following:

5.5.1. 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
GD32E507R-START board has two keys and four LEDs. The two keys are Reset key and
User key. The LED1, LED2, LED3 and LED4 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.
5.5.2. DEMO running result
Download the program < 05_TIMER_Key_EXTI > to the START board, all the LED1 and
LED2 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 PA4 with
DuPont line. The LED2 will be toggled every 500ms.
5.6. USB MSC Device
5.6.1. DEMO purpose
This demo includes the following functions of GD32 MCU:
Learn how to use the USBHS
Learn how to implement USB MSC(mass storage) device
This demo mainly implements a U disk. U disk is currently very widely used removable MSC
devices. MSC, the Mass Storage device Class, is a transport protocol between a computer

User Guide
GD32E507R-START
14/17
and mobile devices, which allow a universal serial bus (USB) equipment to access a host
computing device, file transfer between them, mainly including mobile hard disk, mobile U
disk drive, etc. The MSC device must have a storage medium, and this demo uses the MCU's
internal SRAM as the storage medium. For more details of the MSC protocol please refer to
the MSC protocol standard.
MSC device will use a variety of transport protocols and command formats for communication,
so it need to choose the appropriate protocol and command format in the realization of the
application. This demo selects the BOT (bulk only transport) protocol and the required SCSI
(small computer interface) command, and is compatible with a wide variety of Window
operating systems. Specific BOT protocol and SCSI command specification please refer to
the standard of their agreement.
5.6.2. DEMO Running Result
Download the program < 06_USB_MSC_Device > to the EVAL board and run. When the start
board is connected to the PC, you will find a USB large capacity storage device is in the
universal serial bus controller, and there is 1 more disk drives in the equipment manager of
PC.
Then, after opening the resource manager, you will see more of the 1 disk, as shown in the
following diagram:
At this point, the write/read/formatting operation can be performed as the other mobile
devices.
5.7. USB HID Host
5.7.1. DEMO Purpose
This demo includes the following functions of GD32 MCU:
Learn to use the USBHS as a HID host
Learn the operation between the HID host and the mouse device
Learn the operation between the HID host and the keyboard device
GD32E507R-START board integrates the USBHS module, and the module can be used as a
USB device, a USB host or an OTG device. This demo mainly shows how to use the USBHS
as a USB HID host to communicate with external USB HID device.
