Roger D. Pease- AXI I2C LCD1602 Display

Purpose

I developed this primarily to show my approach to device drivers in Python.

Development

For this project I used:

Zynq TUL-2 Board.
An LCD1602 controller board tied to a PCF8574 pin controller.
A stock Xilinx AXI I2C Module tied into a ZYNQ overlay.

Steps

I built a simple overlay consisting of the AXI Interface and the I2C Module.

And I built a python Interfaces to act as a driver.

This was a fairly simple project but it gave me a chance to show off my device driver skills. It took me about 8 hours, most of that was trying to find readable and reliable information about the LCD Module.
