Overview
There is one green LED in the development board and users can
display the required status through the LED. There are two LEDs left to
facilitate the observation of power supply and FPGA loading status.
You can test the LEDs in the following ways:
When the FPGA corresponding pin output signal is logic low, the LED is
lit;
If the signal is high, LED is off.
