Arduino library for I2C digital potentioMeter AD5243 + rheostat AD5248

## Description
@ -28,22 +28,22 @@ The AD5243 is a digital potentiometer, the AD5248 is a digital rheostat.
Both IC's have two "channels" and they do not have the output lines
some other IC's in these series have e.g. like the AD5242.
The AD5243 has a fixed address (0x2F = 47) while the AD5248 has 2 address pins
giving 4 possible addresses. See table.
The AD5243 has a fixed address (0x2F = 47 decimal) while the AD5248 has
two address pins giving 4 possible addresses. See table below.

An important property of the devices is that they defaults
to their mid position at startup.
The library defines AD5243_MIDPOINT == 127.
The library defines **AD5248_MIDPOINT == 127**.
