There are some issues using this device on the 101 with Firmata: 1. You cannot use any other ADC resolution than 1024. By default the driver would try to set 12b resolution for improved accuracy. Doing this on the 101 yielded nonsensical readings causing the driver to fail. Using 10b resolution will yield less accuracy, but at least the driver will function. 2. After the first ADC read, and for some time period after, the MRAA aio_read() calls will always return 0. This would cause an exception to be thrown by the driver since this is an invalid reading. Now, we do an analog read on each channel and sleep for .5 seconds in the ctor to get around this problem. It is a hack and should be properly fixed somewhere else (firmata? MRAA?). Some code was reworked/renamed to make it more clear what is actually going on. In addition a setDebug() method was added to enable some debugging output. Signed-off-by: Jon Trulson <jtrulson@ics.com>
