Problem reading more than one Analog Chanel on CC3200


Recommended Posts

<p>Hi folks</p>

<p> </p>

<p>I started to use CC3200 in the ENERGIA environment.</p>

<p>I was using the examples from the Book "Arduino projects to save the world"</p>

<p> </p>

<p>I tested the code on an Arduino UNO board, and is OK.</p>

<p> </p>

<p>But in the CC3200, only one Analog channel is printed correctly, in the getADC() function, I can comment any two  // ADC1 = analogRead(A1);  statement and the third will print correctly</p>

<p> </p>

<p> </p>

<p>I am new on ENERGIA so any help will be apreciated.</p>

<p> </p>

<p> </p>

<p> </p>

<p>The code follows:</p>
