Hello everyone,
I confess I am an Arduino noob but I do catch on fast 
I have a program that reads and parses line by line a CSV file on a SD Card. It includes String.h and SD.h. and appears to work properly. I want to use the values on a line to determine a delay and the values of the intensity of fixtures on a DMX system. Sounds easy enough, right? Well as soon as I try to include DmxSimple.h, #include <DmxSimple.h>, well the previously working programs starts to behave very strangely, erratically and sometimes appears to freeze up. Remember, I have not included any DMX functions, just included the header in my program. I am at wits end. I have no new hypothesis to try and solve this. So if anyone here has an idea, all reasonable suggestions will be accepted and welcome.
Regards
Simon
