Welcome to '''The LPCflasher Project'''. Open source hardware for developing open source software. The project is maintained by [[User:linux_junkie|Joseph Smith]].

==Overview==
+
The LPCflasher is low-cost simple flash programming device. It can be used to flash a variety of LPC flash chips and firmware hubs (FWH). The hope is someday it will also be able to support SPI chips. It is also meant to be modular so you can flash a variety flash chip packages. The LPCflasher is based on an old LPC programmer built to flash LPC chips on the xbox, the [http://rex.xbox-scene.com/LPC2/LPC2.html LPC^2 (Low Parts Count LPC Programming Cable)]. The LPCflasher is not for sale, it is meant for that "do-it-yourself" kind of person. Although if the project becomes popular, bare PCB's could be produced and sold at cost. Anyone with novice to moderate soldering skills can build one.
