i guess your rite tuxduino,
actually the real reason for me to make the blink without delay with variable on off time is so that i could make my own code to control a 6 axis Mill. i know big ambition rite. but hay its like what they say in my langguage " Impikan langgit supaya bila jatuh dapat awan" its something like hope for the sky if you fall your atleast in the clouds if im not mistaken. my stepper motor controller is using Step/direction control. i have try countless of library. in my opinions all have its pros and cons. but i know that maybe i could give it a try who knows maybe i can make my own controller, well if i fail atleast i will have learn alot i know some of you thinking while reading this why invent the wheel again and again. just couse i want to learn and nothing more.
