Intel Edison Hardware Pack

NOTE: The ADC Block does not have console access or a voltage

regulator. It is recommended to use a console communication block in

conjunction with this block like ones found in the General Guide to Sparkfun

Blocks for Intel Edison.

C++ Code Examples

We’re assuming that you’re using the Eclipse IDE as detailed in our Beyond

Arduino tutorial. If you aren’t, you’ll need to go to that tutorial to get up to

speed.

Getting Started

Follow the instructions in the programming tutorial to create a new project

named “SparkFun_ADC_Edison_Block_Example”. Once you’ve created the

project, open the project files on disk (hint: you can find the path to the

project by choosing “Properites” from the project menu) and copy the three

source files found in the Edison ADC Block CPP library GitHub repository

into the “src” directory.

Hardware Connection

For this example, we’ve just got two 5k potentiometers connected between

3.3V and GND, with the wipers connected to channels 0 and 1.

V20 of the board adds a 3.3V reference supply (capable of sourcing up to

150mA, so it can power small sensors directly!).

Of course, you can connect any other analog voltage signal in place of the

potentiometers; we’re using them because they’re convenient to

demonstrate the concepts.
