Library for Princeton PT6961 LED driver. Supports 6 digits @ 12 segments or 7 digits @ 11 segments. Also supports keyboard scanning of upto 30 keys. SPI interface.

Dependents:   mbed_PT6961

This LED driver is found in frontpanel controllers of consumer electronics such as DVD players. The added features such as the matrix keyboard scanning are useful in these applications.

Additional information is available on the component page here
