Dependents:   mbed_HCMS2975

Alphanumeric LED display, 8 digits, 5x7 LED pattern. The device has SPI interface. The library supports multiple devices connected in a daisy chain. This provides a 8x1, 8x2, 16x1 and 16x2 display configuration.The library methods are similar to those used for the LCDText library.

These displays are from mid 80s to mid 90s and they look cool, but they are rather expensive ($100 a piece..). The lib was developed and tested with displays salvaged from some equipment. You see them mostly in HP printers, medical equipment etc.

Some info can be found here and here.
