1. Summary
GD32E507Z-EVAL uses GD32E507ZET6 as the main controller. It uses GD-Link Mini USB
interface to supply 5V power. Reset, Boot, K2, LED, I2S, I2C-EEPROM, LCD, NAND Flash,
SQPI-Flash, USB, Ethernet and USART to USB interface are also included. For more details
please refer to GD32E507Z-EVAL-Rev1.1 schematic.

3. Getting started
The EVAL 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.

5.1.1. DEMO purpose
This demo includes the following functions of GD32 MCU:
Learn to use GPIO control the LED
Learn to use SysTick to generate 1ms delay
GD32E507Z-EVAL-V1.0 board has five user keys and four LEDs. The keys are KEY_A,
KEY_B, KEY_C, KEY_D and KEY_Cet. The LEDs are controlled by GPIO.
This demo will show how to light the LEDs.
5.1.2. DEMO running result
Download the program < 01_GPIO_Running_LED > to the EVAL board, four LEDs can light
cycles.
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
GD32E507Z-EVAL-V1.0 board has five user keys and four LEDs. The keys are KEY_A,
KEY_B, KEY_C, KEY_D, and KEY_Cet. The LEDs are controlled by GPIO.
This demo will show how to use the KEY_Ato control the LED2.When press down the KEY_A,
it will check the input value of the IO port. If the value is 0 and will wait for 100ms. Check the
input value of the IO port again. If the value still is 0, 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 EVAL board, press down the
KEY_A, LED2 will be turned on. Press down the KEY_A 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
GD32E507Z-EVAL-V1.0 board has five user keys and four LEDs. The keys are KEY_A,
KEY_B, KEY_C, KEY_D, and KEY_Cet. 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 KEY_B, 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 EVAL board, LED2 is turned
on and off for test. When press down the KEY_B, LED2 will be turned on. Press down the
KEY_B again, LED2 will be turned off.
5.4. USART_Printf
5.4.1. DEMO purpose
This demo includes the following functions of GD32 MCU:
Learn to use GPIO control the LED
Learn to retarget the C library printf function to the USART
5.4.2. DEMO running result
Download the program < 04_USART_Printf > to the EVAL board, connect serial cable to
USART0 and jump JP13 to USART. Firstly, all the LEDs are turned on and off for test. Then,
this implementation outputs “USART printf example: please press the KEY_B” on the
HyperTerminal using USART0. Press the KEY_B, the LED1 will be turned on and serial port
will output “USART printf example”.
The output information via the HyperTerminal is as following：

5.5. USART_HyperTerminal_Interrupt
5.5.1. 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.
5.5.2. DEMO running result
Download the program <05_USART_HyperTerminal_Interrupt> to the EVAL board, connect
serial cable to USART0 and jump JP13 to USART. Firstly, all the LEDs are turned on and off
for test. Then, the USART0 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:
5.6. USART_DMA
5.6.1. DEMO purpose
This demo includes the following functions of GD32 MCU:
Learn to use the USART transmit and receive data using DMA.
5.6.2. DEMO running result
Download the program <06_USART_DMA> to the EVAL board, connect serial cable to
USART0. Firstly, all the LEDs are turned on and off for test. Then, the USART0 sends the
tx_buffer array 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:
5.7. ADC_Temperature_Vrefint
5.7.1. DEMO purpose
This demo includes the following functions of GD32 MCU:
Learn to use the ADC to convert analog signal to digital data
Learn to get the value of inner channel 16(temperature sensor channel) and channel 17
(Vrefint channel)
5.7.2. DEMO running result
Download the program <07_ADC_Temperature_Vrefint> to the GD32E507Z-EVAL-V1.0
board. Connect serial cable to USART0, open the HyperTerminal.
When the program is running, HyperTerminal display the value of temperature and internal
voltage reference.
Notice: because there is an offset, when inner temperature sensor is used to detect accurate
temperature, an external temperature sensor part should be used to calibrate the offset error.
