Displaying aprx-rf log onto 4x20 LCD display

Received a request on a short how-to to get the aprs packet shown in the 20x4 LCD display. The way I have for my setup are the following:

1. Raspberry Pi 3 (Raspberry Pi 2 will work, but below that, you need to have different kind of connection for the GPIO).
2. 20x4 LCD HD44780 or compatible screen.
3. Install lcdproc package ($ sudo apt-get install lcdproc)
4. A modified HD44780 driver,

I'm using the following diagram for my LCD connection to the GPIO lines. Ignore the temp sensor connection.

The how-to to get the LCD working can be found on the too.

A modified HD44780 driver can be found down below along with my python code.

Or download or compile your own following the thread in the following forum link:

This modified driver need to be moved into /usr/lib/arm-linux-gnueabihf/lcdproc/ directory and replacing the driver that comes with the lcdproc package…
