// This is a 7-bit address, that gets left-shifted and bit 0
|
||||
// set to 0 for write, 1 for read (as per I2C protocol)
|
||||
// The address will vary depending on your wiring:
|
||||
// 00 <-> GND
|
||||
// 01 <-> SCL
|
||||
// 10 <-> SDA
|
||||
// 11 <-> VCC
|
||||
// ADDR1 represents A1:A0 of the 7-bit address.
|
||||
// ADDR2 represents A3:A2 of the 7-bit address.
|
||||
// The result is: 0b010(ADDR2)(ADDR1)
