unsupported mode '2' for pin '15' at ../lib/Device/Firmata/Platform.pm line 823.

[bcarroll]

examples/test.pl is producing an error "unsupported mode '2' for pin '15' at ../lib/Device/Firmata/Platform.pm line 823."

This test was done using an Arduino Mega 2560 R3 and the StandardFirmata sketch included with Arduino 1.0.5.

I did not get this error with an Arduino Nano v3.

The firmata.org WIKI mentions changing the samplingInterval to 99 to support all pins on the Arduino Mega, but I thought that had been included in the newer versions of the StandardFirmata sketch.

[bcarroll]

looks like samplingInterval is set to 19 by default.
int samplingInterval = 19; // how often to run the main loop (in ms)

I changed it to 99, but the results are very different.

Results with samplingInterval=19;
