Preview: Bus Pirate LCD adapter v2

Posted on Thursday, July 29th, 2010 in Bus Pirate, Bus Pirate accessories, Development by Ian

This is a new LCD adapter for the Bus Pirate. The board has been tested, Seeed is building a manufacturing prototype now. The Bus Pirate LCD library in firmware v5.4+ will require this LCD adapter instead of the old v1 adapter.

The v1 LCD adapter was based on a PCF8574 I2C IO expander IC. It took more than a second to update a 4×20 LCD screen, and the production price was too high to justify producing any.

The v2 adapter uses a cheap 74HCT595 8bit shift register instead. It has an SPI interface for blazing fast screen refreshes.

Read more about the v2 LCD adapter features and download the preliminary Eagle files in the forum.
