Ok, here it is, my first attempt! Although it may be a little too much for a beginner but if I can accomplish this I am way ahead...
So... I decided that I want to build a 1 byte interval transmitter and receiver.
I thought about it for a while and I think this is a very good attempt at learning many things at the same time.
Description:
- I want to transmit 1 Byte of data (hard coded (for now!)) each 10 seconds.
- I want to receive that 1 byte of data and read it via the parallel port of the computer.
My basic diagram is as follows: (any suggestions?)
Transmitter:
0/7-(hard coded bits)---[MUX]--[TIMER]--[D/A]---[Transmitter]--[antenna]
Receiver:
[antenna]----[Receiver]----[A/D]-----[DEMUX]--0/7 lines--[PC PARALLEL PORT]
I know how to interface to the computer so I don't need any help on that for now.
I just want to if my design is logical and/or if I am missing any major components.
Also, I want the range to be less than 10 meters but I don't want to use a standard like 802.11b or anything like that.
Which standard (or if any) should I think about and what frequency (more importantly)
The goal is to keep it simple and functional and learn something from it!
I need lots of help on this so please be gentle on the criticisms though very much appreciated.
I just found out that we have Orcad 10.5 available at my workplace, so I installed it and played with it a bit. Does anyone have experience with that and how can I use it for this project?
Thank you very much.
