Hi guys, I'm encounting some problems here in programming microcontroller. I wana use a pic microcontroller which is connected to a wireless module to transmit a protocols out. How do we write the c language for transmitting the protocols normally? I just wanna get some examples....
Can u guys please teach me?
Some questions spring to mind:
What protocol?
What model of PIC?
What model of Wireless module?
Does the manufacturer of the Wireless module not have some examples of how to use it?
How much C programming experience do you have?
How much assembler do you know?
Have you ever programmed something that talks directly to hardware devices?
Unfortunately, I don't think answering these questions will give you a direct answer, but perhaps they will at least give us something we can work with - as your current question is a bit like me walking into a car mechanics shop asking "How do I put a turbo on my engine?" - to achieve that I would at least have to have:
- prior experience in modifying engines
- a decent workshop with sufficient tools
- plenty of time.

I'm using the Atmel 894051 microcontroller. the wireless module is the XBEE pro. I need to send wireless protocols out to a receiver which is the XBEE pro also. I jz wan some example as how to write the source code especially the transmitting protocol part.
Now that you have answered the first two, perhaps can you answer the other 6 questions I asked?
It may not be very difficult to write the code for someone who has decent experience, but if you have never written code for hardware before, I think you may need several weeks to get it right.

I would google and/or call the wireless manufacturer for info and examples. Hard to believe they wouldn't include this info with their product.
no example given cos no need to program the wireless module, Jz wan to program the microcontroller. I got a bit of experience in programming hardware...especially programming the microcontroller. plz teach me...
I would think that if they want to sell at least a few, they do have some examples. However, they may of course assume that the user has some idea of how to program a serial port, as the prototype/sample board that they show in the datasheet appears to have a 9-pin DSUB that would connect to a PC, so my guess would be that any sample software is just a windows/linux program to send an receive data via the serial port API.Quote:

the manufacturer jz produce the wireless module....it is for transmit n receive wirelessly only. i jz wanna modify it to connect wif a microcontroller so that i can send some wireless protocols
Do u guys know what functions n variables we have to use to transmit wireless protocols? like transmit this: 02 80 81 80 8F 33 03
There is no standard way to do that. You need to look into the specs of that particular Atmel part, and how the serial port of that device works.Quote:

What the hell does "i jz wanna modify it to connect wif" mean?

I just wanna know how to write the function normally....Just normally. It musn't be the best answer guys. Just give me some idea...
Do you understand the concept of "There is no standard way to do this" - there isn't a magical function that does this for you, unless someone else has the same type of device and has already written one.
Fortunately, there are still challenges of writing code for some things. Otherwise I (and my wife and two children) would be out of a job -> no money -> no mortgage being paid -> homeless.
