Simple library for controlling the Toshiba ICs TC9162, TC9163, TC9164, and TC9459 with an Arduino.
It is tested with an Arduino Leonardo controlling one TC9163AF, one TC9164AF, and one TC9459F IC on the same DATA, CK, and ST lines.
The library provides one class per IC type, which may be instantiated:
TC9162
TC9163
TC9164
TC9459
TC9162, TC9163, and TC9164 are instantiated in the same way:
TC9162 myIC(dataPin, clockPin, strobePin);
where the parameters give the pin names of the three connected communication lines (s. extras/pinouts.txt):
dataPin = DATA
clockPin = CK
strobePin = ST
After instantiation, the method
sendCommand(switchConfig, channel)
may be used to request a switch configuration for one or two channels (channel = {LEFT, RIGHT, BOTH}). E.g. if you want to close only the switches S1 and S7 on both channels, use:
sendCommand(0b01000001, BOTH);
The class TC9459 must additionally be given the IC address (as wired by CS1 and CS2, s. datasheets) when instantiated:
TC9459 myTC9459(dataPin, clockPin, strobePin, address);
For the TC9459 class, the method
sendCommand(leftAttenuation, rightAttenuation, loudness)
may be used to request the desired volume level and loudness. E.g. if you want to set the volume to -10dB attenuation and no loudness, use:
sendCommand(10, 10, false);
