Spyy

Sorry, shawn it was not my intention to ignore anyones suggestions here....sorry for this....was faster with trying things and writing here.... Do not be angry with me....

...after some testing i found this works (monitored the changes when the parameter where changed in the IDE)... SPEED := speed=528,opt=o3std => 528Mhz and fastest BOARD = teensy:avr:teensy41:$(SPEED) => So it seems it is possible to add somthing...

Ah, wow thank you, will try.... And what about adding some defines (like this -DTEENSYDUINO=159) to control the #ifdef ?
