LPT_Display.zip (download package, 72 kB)The download package contains the executable, driver and HTML-documentation files. Save and decompress the archive file into your desired folder.
LPT-Display.exe is a dialog-based Windows standalone executable and should run as You double-click it.
LCD-Browser_V2-1.zip (download package, 353 kB)LCD-Browser is an alternative to LPT-Display.exe to test displays, which runs on a separate microcontroller system connected to the HD44780 display instead of a computer connected to the display via LPT-port.
It has less experimental functionality and simply browses through each page of the HD44780's memory bank and shows it's contents on the display. Usage of the three buttons (from left to right) is RESET, BROWSE-BACK, BROWSE-FORWARD.
Included in the ZIP-folder are fotos of example hardware layout and pcb illustration plus a EAGLE-.brd file (you must adjust two jumper-routings by yourself, for they are routed as copper across other wires in this pcb-file), as well as the "binary" firmware-file itself (intel-HEX-format), which can be downloaded onto the microcontroller by use of a compatible programming-device.
This version (firmware V2-1) is compiled with MPASM for Microchip's PIC16F505 (TM) microcontrollers, and may be run as freeware just like LPT-Display.
The example hardware, as shown, can be run at voltages between 3Vdc...5Vdc, thus USB powered usage is possible.
