AD7705/AD7706 Library Revisited

About a year ago, I wrote a simple library for interfacing AD7705/AD7706 with Arduino. The library works, but it requires some decent knowledge of the underlying chip, which had made it somewhat difficult to use. Most issues users reported can be resolved by adjusting the timing in user code, but I admit that it is somewhat difficult for users who are not familiar with the chip. For a library, I should have made it easier to use to begin with. So, I decided to add a few long-awaited features and hopefully these tweaks will make the library easier to use.

AD7705/AD7706 Library

AD7705 and AD7706 are two 16-bit Sigma Delta ADCs. Equipped with on-chip digital filters and programmable gain front ends, these chips are ideal for low frequency multi-channel signal measurements. The main difference between AD7705 and AD7706 is that AD7705 has two fully differential input channels while AD7706 has three pseudo differential input channels.
