Thanx for the response profrob. It seems to be working now and I really don't know what I did to convince it to work. Now I seem to have to understand the differences between Arduino and Eclipse. Oh yea and I'm working with Teensy 4.x, so another level of "jump right in head first". I can't seem to make the EEPROM.h library work. All other lib's seem to work but EEPROM gives me a "Symbol 'EEPROM' could not be resolved". if I select the include name then request the definition it goes right to it. but wont actually include it.......and yes...I don't know what I'm doing so I can only go up. But I like what I see so far.
