Part 3.14: LED Light

There are 7 red LEDs on the AX7A035 FPGA carrier board, one of which
is the power indicator (PWR), two are USB Uart data receiving and transmitting
indicators, and four are users LED lights (LED1~LED4). When the board is
powered on, the power indicator will light up; User LED1~LED4 are connected
to the normal IO of the FPGA. When the IO voltage connected to the user LED
is configured low level, the user LED lights up. When the connected IO voltage
is configured as high level, the user LED will be extinguished. The schematic
diagram of the user LEDs hardware connection is shown in Figure 3-14-1.
