Version 9.51 for a 4 line 40 character LCD (this is the same as version 10.00 except it supports a 4 line display)
I've written the 9.51 version for a 4 line display. Two LCDs have been trialled
(1) HDM40416L from Futurlec.
(2) LKC-4004 from lcdmodkit.com
I've used the extra two lines and the wider display to permanently display the UTC time and local time (offset is set in the menu), moon declination and display the doppler shift and the frequency when the moon is above the horizon. Because this LCD actually has two controllers on board I have had to use the unused DTR pin on the computer interface J1 (pin 4) to enable the second controller for the bottom 2 lines. If you are interested send me an email.

Wiring a 4 line display with Version 9.51
The four line displays used in this version of the project are really two displays in one. There
are two enable pins and the system works by enabling the top two lines, writing the
information, then disabling the top display and enabling the bottom two lines then writing the
information there. It all works quite well.
You will need to check the data sheet for the display you buy. It must be HD44780
compatible. Locate the two enable pins. The first enable pin goes to the usual pin 6 on P1 of
the main board. The second enable pin goes to pin 4 of J1. In the original version this pin 4
was the DTR connection to the computer, this is no longer used for that purpose and has been
programmed in the four line LCD version to be a second enable pin.
