coding for the development of hand held billing machine

arungksolutions wrote a year ago • 1 point

I am a beginner in the embedded programming. I have done some engineering projects using ARM7 microcontroller. Now I have a new project developing the software for hand-held billing machine using ARM microcontroller. So I just need some help regarding the coding of handheld billing machine software for ARM microcontroller in Keil ╬╝Vision. I need some sample programs or any sites from where I should get help regarding these things or some tips for the development.

This answer propably falls under "some tips", as I've dealt with uVision over two years ago in universiy only. Your question is so unprecise/unstructured, it is imposible for me to find an answer that would be better than a web search (e.g. uvision tutorial)...

"Beginner / done some engineering projects using ARM7" - does this refer to HW or SW? If SW, what niveau? What kind of sample programs (blinking LED? linux ARM port?)?

You need to structurize the thing in some way (e.g. create a list of requirenments, try to figure out what to do to fulfil them one by one and/or in conjunction (in general and for this particular platform),...) to get down to simpler questions/web search terms etc.
