Part 3.19: User Leds - Alinx UltraScale+ AXU4EV-P User Manual

Semiconductor. The temperature accuracy of the LM75 chip is 0.5 degrees.
The EEPROM and temperature sensor are mounted on the Bank500 MIO
of ZYNQ UltraScale+ through the I2C bus. Figure 3-18-1 is the schematic

Part 3.19: User LEDs

There are 3 LEDs on the AXU4EV-P Carrier board. including 1 power
indicator light, 1 User LED Controlled by PS side, and 1 User LED Controlled
by PL side. The user can control the user LED on and off through the program.
When the IO voltage of the connected user LED light is low, the user LED light
is off, and when the connected IO voltage is high, the user LED will be lit. The
schematic diagram of the user's LED light hardware connection is shown in
