wireless LCD

Post by demoman »

I got one of the special wireless LCD prototypes (uses the BASICchip and a NewHaven display)

And have a quick demo running on it in BASIC (source below)

This was a prototype we built for a customer that linked Xbee wireless module to a display. We built a few, but it never became a product.

It could be re-designed for Bluetooth or WiFi.

We've updated this project with an LPC812. Character LCDs have become plentiful and inexpensive. Some use an I2C I/O expander, but that is relatively slow to control as every byte access requires 6 operations.

An LPC812 can be used to implement a serial interface with a higher level commands.

This original BASIC code has been updated for the LPC812.
