hi every one i am strucked while thinking of this i am working on LPC2148 RTOS , i have to run 3 stepper motors X axix,y axis and Z axis and control their directions using using computer hyperterminal (i am planning to use hyperterminal as a KEYBOAD for controlling the stepper motor directions, to START and to STOP )... please can anyone tell me how to implement this using RTOS
You didn't answer why you have to do this?
Since you don't seem to have the skills to either do it yourself, or even find out how to do it yourself, why are you having to do this? What is it that compels you?
Embedded software development is not for everyone - fair enough. If you're not interested in doing it yourself, then look for someone to do it for you - but don't expect them to do it for free! You could look here: http://www.keil.com/condb Or, as you have an NXP chip, here: ics.nxp.com/.../ Or sites like these: http://www.vworker.com/ http://www.zintro.com/home
Again, what work have you done yourself on this so far?
Have you found out the basics of how to drive just one stepper motor without an RTOS?
"i need some suggestions/guidelines"
OK, here is a suggestion: the first thing you need to do is to find out the basics of how to drive just one stepper motor without an RTOS
