bug - Changing Trellis library to pull from i2c_t3 (I2C for Teensy 3.0/3.1) using Wire1 enables trellis to work HOWEVER, it also changes Wire0 for the amp at the same time :/
// initialize the library with the numbers of the interface pins LiquidCrystalFast lcd(14, 15, 16, 20, 21, 22, 23); // LCD pins: RS RW EN D4 D5 D6 D7
// Change these pin numbers to the pins connected to your encoder. // Best Performance: both pins have interrupt capability // Good Performance: only the first pin has interrupt capability // Low Performance: neither pin has interrupt capability Encoder knob1(2, 3); Encoder knob2(5, 6); Encoder knob3(8, 9); Encoder knob4(11, 12);
