5.1. 

 GPIO_Running_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 1ms delay 

GD32130C-START-V1.1 board has two LEDs. The LED1 and LED2 are controlled by GPIO. 

This demo will show how to light the LED. 

5.1.2. 

 DEMO running Result 

Download  the  program  <01_GPIO_Running_LED>  to  the  board,  the  states  of  LED1  and 

LED2 are toggled every 200ms. 

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 

GD32130C-START-V1.1 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  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 0, wait for 100ms. Then 

check the input value of the IO port again. If the value is still 0, indicates that the button is 

pressed down successfully, and light the LED2. 

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.
