Function Documentation

i2c_address()

uint8_t esphome::weikai_i2c::i2c_address ( uint8_t  base_address, uint8_t  channel, RegType  fifo  )

inline

Computes the I²C bus's address used to access the component.

Parameters

base_address	the base address of the component - set by the A1 A0 pins
channel	(0-3) the UART channel
fifo	(0-1) 0 = access to internal register, 1 = direct access to fifo

Returns

the i2c address to use
