Overview
Lcd Booster3 is an open-source printed circuit board by hvontres, from the hvontres/LCD-Controller repository on GitHub. It is a 2-layer board of 82.6 × 38.1 mm with 37 parts on 79 nets, routed with 368 tracks and 15 vias.
It is built around the 74LS245SC and MAX774CPA+. Its parts include 9 resistors, 8 capacitors, 6 connectors, 4 ICs and 2 diodes. It belongs with the lEDs and displays boards and the MSP430 boards of this library.

Stellaris+Msp430 Lcd Controller
This software is designed to run a 320x240 monochrome LCD with minimal CPU overhead.
A seprate controller board supplies the VEE for the display, controls the Backlight and has a MSP430G2542 running as a SPI Master. The MSP also controls the clocks for moving the data to the display.
The Stellaris side sets up a 1BPP offscreen display for Grlib and also sets up a UDMA job that transfers the display buffer to the SPI port for the MSP to collect.
The SPI connection is set up to transfer 16 bits at a time, allowing for 4 pixel updates for each transfer. With the SPI clock running at 8Mhz, the display can update at ~51 Hz.

This project has been built on linux using gcc for the Stellaris and naken_asm for the MSP430.
-
get gcc toolchain: https://github.com/esden/summon-arm-toolchain or https://launchpad.net/gcc-arm-embedded
-
get naken_asm: http://downloads.mikekohn.net/naken_asm/naken_asm-2012-09-02.tar.gz make sure that naken_asm is on your path, or make won't find it.
-
install stellarisware
-
edit the TOOL and SW_DIR varables in the makefile to point at your arm toolchain and stellarisware.
-
run make all.
-
the easiest way to program the MSP430G2542 is by putting it in a launchpad and running mspdebug. Alternatively, there is a debug headder on the controller board. This should work fine, as long as the EK-LM4F120XL is NOT installed.

Questions
How big is the Lcd Booster3 PCB?
It measures 82.6 × 38.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Lcd Booster3 use?
37 parts, built around the 74LS245SC and MAX774CPA+. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Lcd Booster3 KiCad files?
From the hvontres/LCD-Controller repository on GitHub, at the commit this page was made from: the board is Hardware/LCD Driver/Lcd Booster3.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Lcd Booster3 design in my own project?
Its repository states no licence, so its author keeps all rights: ask hvontres before reusing the design.
