Part 15: LED Light
The AX7350B FPGA development board has 9 LEDs, 1 power indicator; 1
DONE configuration indicator; 2 serial communication indicators, 1 PS control
LED, and 4 PL control indicators. The power indicator will illuminate when the
board is powered on; the configuration LED will illuminate when the FPGA is
configured. One user LED light is connected to the MIO of the PS, and four
LED lights are connected to the IO of the PL. The user can control the lighting
and extinguishing through the program. When the IO voltage connected to the
user LED is low, the user LED is off, and when the connection IO voltage is
high, the user LED is illuminated. Since the level of BANK34 is 1.5V, here we
have added a Transistor to drive the LED on and off. Figure 15-1 detailed the
LED light hardware connection diagram
