I'm trying to interface a BS2px to a 32054 LCD 4x20 display I got from MPJA Electronics. They sell surplus gizmos - with little or no documentation. It has a piggy-back board for I2C interface. I see all kinds of Arduino code online, but nothing for Parallax. Has anyone done this and if so can you supply me with a little code to send ASCII characters to the display?
Any help is appreciated.
