Arduino Toolkit - @i2cdev/read

: data = read (dev, numbytes)

: data = read (dev, numbytes, precision)

Read a specified number of bytes from a i2cdev object using optional precision for bytesize.

Inputs

dev - connected i2c device opened using i2cdev

numbytes - number of bytes to read.

precision - Optional precision for the output data read data. Currently known precision values are uint8 (default), int8, uint16, int16

Outputs

data - data read from i2cdevice
