Signal stability problems

Fri, 26 Jul 2019 10:30:09 GMT

Hey guys, I'm having troubles getting a fully stable and reliable signal. What are the main sources of troubles ? I'm running numerous (20) Boolean variables to address electro-magnets, to form different activation patterns. See the link below to acces the grasshopper definition and a few pics. I'm getting signal but sometime, activating an electro-magnet will disactivate others. Other times I need to turn it off and on a few times to get it to work. Is there main known issues ? Also I don't get 2 mega boards to work from the same computer. One always keeps giving me the "Woops, it seems that you tried to start writing data to the Arduino board before opening the Serial Port. Try using the Open Port component to open the serial connection before setting the Start boolean to True." Thanks for your help guys, O'Malley
