Usage Zynq7000

To use the LCD display with the

Zynq7000 together with https://flink-project.ch/, you need a GPIO subdevice within flink. Connect it in the following way:

There are two drivers available. One for

Python when using a Linux operating system and one for Java in combination with deep. 

• Python driver
• Java Driver

Python Example

import driver
import time

# init LCD

disp = driver.HD44780U()
disp.init(2)

# write to display
a = 87103
disp.writeString(str(a))
disp.setCursor(1,5)
disp.writeChar('A')
disp.writeChar('x')
time.sleep(3)

# clear display
disp.clearDisplay()

# turn on display and turn off blinking and cursor
disp.onOff(True, False, False)
