hi iam using samsung s3c2440 ARM9 board . i don't know how to access its ports and installation of os. where i can get c program code for accessing its ports. actually i want to interface stepper motor from its GPIO and how we can read its user buttons. i wrote some program for reading user button but it is not working. can anybody tell me how i can start with this board?
It sounds like what you really need is basic study/training on the the fundamentals of microcontroller development?
