problem with processing writing (serial.write) lightsarray

[sfranzyshen]

The serial write of lightsarray in processing ins't working as expected ... 'show all leds' on and off is working ... but when I try and do an auto mapping more than one led lights up simultaneously (up to 3 of them) during the mapping process ... usually one of them is colored red ... also with the 'showLedUnderMouse' more than one led lights up ... and nowhere near the mouse ... I have tested the arduino side of things and it seams to be coming from the byte serial write out of processing ... is this a versioning issue maybe? what version's were used for development? Is this possibly a signed unsigned issue perhaps in doSingleLED()? Is it even necessary to send the whole led array (lightsarray) over serial each draw frame to do this? couldn't it just be a simple protocol to step through the leds one by one?
