Character LCDs / NHD-C0220Biz and Arduino/Teensy3.1
« on: April 24, 2015, 11:24:07 AM »
Hello, the I2C connection between the C0220Biz and my Teensy3.1 locks up when it is first initialized. Other I2c devices work fine, so I'll assume i am doing something wrong at initialization. Is there a library that will work for a teensy3.1 and a C0220Biz? It looks as if the address is 0x78. I have all the hardware connections as peer the Pin description and wiring diagram, and my supply volage to vdd is 3.3 regulated.  :-\
