I am experiencing some difficulties with getting Maxuino to work with my Arduino Mega. I have opened up the maxuino.help patch to try and get myself started, however I am unable to make any meaningful communication with the Arduino happen. The Rx light flashes to show that there is some degree of connectivity, however I am unable to do even simple things like flash pin 13. When I open up the Maxuino GUI as a standalone patch I experience the same difficulties. Does anyone have any ideas?
