<DIV>I have been experimenting with GPIO on the RPI2</DIV>
<DIV> </DIV>
<DIV>I am using Doug's document for the instructions</DIV>
<DIV> </DIV>
<DIV>I have a question.</DIV>
<DIV> </DIV>
<DIV>Since Asterisk is initializing the URI for PTT, COS, and audio in / out,
the document suggests that GPIO 19 and GPIO 26 should represent COS and PTT
respectively.</DIV>
<DIV>However from the Linux prompt</DIV>
<DIV>read gpio26 always returns a zero</DIV>
<DIV>and read gpio19 seems to return nothing</DIV>
<DIV> </DIV>
<DIV>I am assuming (most likely incorrectly) that the following are true</DIV>
<DIV>1. Asterisk has allready defined gpio19 as an input and GPIO26 as an
output</DIV>
<DIV>2. That it is possible just to issue an READ GPIO19 or READ GPIO26 COMMAND
AT THE lINUX PROMPT WITHOUT ANY FURTHER SETUP SINCE
aSTERISK HAS ALLREADY DEFINED THESE PINS</DIV>
<DIV> </DIV>
<DIV>sO WHAT AM I DOING WRONG?</DIV>
<DIV> </DIV>
<DIV> </DIV>
