It’s been about 3 years now since I last compiled up avr-gcc and avr-libc for Windows and it proved surprisingly popular with you so I’m now bringing you the latest, as of March 2015, versions of avr-gcc and avr-libc. I’ve also included avrdude 6.1 for completeness even...

Arduino Uno R3 graphics accelerator shield uses no pins
posted by Andy
Hello and welcome to another in my series of unique hardware projects designed to bring you something useful that you’ve hopefully never seen before and at a price point that any hobbyist can afford. This project brings together the knowledge that I’ve gained over the last few years to bring you a graphics accelerator for the Arduino Uno R3 based on an ARM Cortex M0 core attached to a 640×360 LCD from the Sony U5 Vivaz cellphone. In previous articles you’ve seen how I’ve reverse engineered the Sony LCD and then used it in reflow oven and FPGA graphics accelerator projects. Introduction TFT LCD shields for the...
Reverse engineering the Sony Ericsson Vivaz high resolution 640 x 360 cellphone LCD

Welcome to another in my series of cellphone LCD reverse-engineering articles. In this article I’m going to present everything you need to hook up the high-resolution 640×360 LCD from the Sony Ericsson U5 Vivaz to your project. About the phone and LCD The Sony Ericsson U5 Vivaz LCD...
A generic optimised 16-bit LCD adaptor for the Arduino

There are many TFT modules available on the market that are designed to connect directly to an MCU to provide a full colour graphical display, just search ebay for “tft module” to see what I mean. Unfortunately for Arduino users the majority of these modules expose a 16-bit...
Reverse engineering the Nokia E73 QVGA LCD

Readers with a keen memory will no doubt recall that I said that the N93 would probably be the last of the Nokia QVGA LCDs that I attempt to reverse engineer. However probably is not definitely and one day whilst browsing ebay my finger slipped and next thing I knew I’d got myself an...
Arduino Mega 512K SRAM in shield format
posted by Andy
Some time ago now I presented the design, development board and software driver for an add-on to the Arduino Mega that gave it access to 448Kb of additional SRAM arranged in 8 banks of 56Kb. My design was realised by a compact add-on board that plugged into the relevant block of pins on the...
Reverse engineering the Nokia N93 QVGA LCD

Welcome to what will probably be the last in the series of articles in which I reverse engineer one of the Nokia QVGA cellphone displays from the pre-smartphone era. I think that by now I’ve covered every possible aspect of these incredibly cost effective little displays and hopefully...
Reverse engineering the Nokia N95 8Gb QVGA LCD
posted by Andy
In this, the latest instalment of my Nokia QVGA TFT reverse engineering series, I will take on the 2.8 inch 24-bit TFT that is designed to work with the Nokia N95 8Gb mobile phone. Read on to see how it worked out. Background In the first of my reverse engineering articles I tackled the Nokia 2730 display. I successfully discovered enough of the command set to write a driver for the Arduino and the STM32. Flush with that success I moved on to tackle the Nokia 6300 and the Nokia N82. I was lucky in that these two shared the same pinout and command set as the 2730 so I could produce a development board with little difficulty. The N95...
