A weblog focused on interesting circuits, ideas, schematics and other information about microelectronics and microcontrollers.
LCD to USB
The goal of LCD2USB is to connect HD44780 based text LCD displays to various PCs via USB.
It is therefore based on the Atmel AVR Mega8 CPU and does not require any difficult to obtain parts like separate USB controllers and the like. The total cost (without display and pcb) are about 10 to 20 USD. LCD2USB currently comes with a simple demo application that works under Linux, MacOS X and Windows.
LCD2USB is currently supported by lcd4linux (LCD2USB support is built-in), LCD Smartie (requires a seperate driver), and LCDProc (LCD2USB support is currently in the nightly builds).
