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 1ms delay
GD32350R-EVAL board has four LEDs. The LED1, LED2, LED3 and LED4 are
controlled by GPIO. This demo will show how to light the LEDs.
5.1.2.
DEMO Running Result
Download the program <01_GPIO_Runing_Led> to the EVAL board, four LEDs will turn
on one by one from LED1 to LED4 every 200ms, and then turn off together. 200ms later,
