Hi Varunme,
I think it is good to know them bcz ....I was involve in the design of one of the system where...it have 3 different input....one is sensor output, second is temperature and third is control of the resistance to get temperature compensated results from the system....I used PIC16F877a and things are working for me...of couse we need to have some level of multi-input concepts and state machine implementation...realy helps....while doing the work that I said above ....I was refering Internet like hell.... as many things are not even know to me....simillarly if I see the problem in the motion control addressed by the Micro-controller....may be it will help if you have Kinematics knowledge at two stages....First for debug of the code and sencond for the code optimization....
with regards,
Milind
