+# ADG725
+
+Arduino library for ADG725 - 16 to 1 channel (2x) multiplexer.
+
+
+## Description
+
+**Experimental**
+
+ADG725 is an Arduino class that controls two 16 to 1 multiplexers 
+over a SPI like interface.
+Only one of the 16 channels can be connected at the same time.
+The channels can be set per multiplexer or together in one call.
+The library also support to set them all off (17th state).
+
+On power-up, all switches are in the OFF state.
+
+This library can be used e.g. to connect 16 analog devices to 
+one analog port, or to select between 16 DHT22 sensors.
+
+Not tests with hardware have been done yet, so use with care.
+Feedback welcome!
+
+
+TODO insert picture.

+## Interface
+
+```cpp
+#include "ADG725.h"
+```
+
+- **ADG725(uint8_t clockPin, uint8_t dataPin, uint8_t syncPin)** constructor.
+- **void setChannel(uint8_t channel)** set the current channel for both A and B.
+Valid values for channel are 0..15.
+- **void setChannelA(uint8_t channel)** set the current channel for A only.
+Valid values for channel are 0..15.
+- **void setChannelB(uint8_t channel)** set the current channel for B only.
+Valid values for channel are 0..15.
+- **uint8_t getChannelA()** get last set channel A == 0..15 or ADG725_ALLOFF.
+- **uint8_t getChannelB()** get last set channel B == 0..15 or ADG725_ALLOFF.
+- **uint8_t channelCount()** returns 16 for ADG725.
+
+
+## Future
+
+#### Must
+
+- improve documentation
+- test with hardware
+
+#### Should
+
+- add examples
+- check performance
+
+#### Could
