I was trying to replicate your issue, so I downloaded the DataMonsterCpp. I don’t know if I’m trying with a different file but I was able to compile DataMonster.ino without any errors. One thing I noticed is that I accidentally open that file and it opened the Arduino 1.0.5 and it displayed an error that the SPI library was needed, after I added the SPI library it still showed some errors and they were related with the SPI not identical to yours but similar I don’t know if that helps, at that moment I realized I was in the wrong IDE. Then I opened the IDE 1.5.3 and it compiled successfully. I would like to know Is the MonsterSketch.ino the one you are having issues with, right?
Thanks for replying. I must have made a similar mistake. While on the Mac I checked I was opening 1.5.3 but was still getting the error. I installed a clean copy of 1.5.3 on my Linux machine and MonsterSketch compiled without any problems. I'll have to clean the Mac up and try to get it working properly. I have both IDEs there.
Thanks again for taking the time to check that. I have 95% of the Data Monster components here minus 2 servos. Looking forward to working with it.
