jksoft 0:9fcc79b3f00e 8 These displays use I2C to communicate, 2 pins are required to
jksoft 0:9fcc79b3f00e 9 interface. There are multiple selectable I2C addresses. For backpacks
jksoft 0:9fcc79b3f00e 10 with 2 Address Select pins: 0x70, 0x71, 0x72 or 0x73. For backpacks
jksoft 0:9fcc79b3f00e 11 with 3 Address Select pins: 0x70 thru 0x77
