Propeller as RF xmitt/receiver

Areal Person

Hi,
·
I’m working with the Radiotronix RCT-315-AS XMITT/RCV module.
·
Here’s the general circuit I’m implementing
http://www.radiotronix.com/downloads/433_pair.pdf
·
And here the info on the xmitter
http://www.radiotronix.com/products/proddb.asp?ProdID=112
·
It uses the Holtek HT12/E & D encoder/decoder IC pair.
·
I’m wanting to use the propeller to send/receive the simple data bit signal
but I’m really new to doing this stuff.
·
QUESTION 1:
·
Do I still have to use the Holtek encoder/decoder IC pair if I use the propeller ?
Can I just use the basic stamp functions SHIFTOUT etc.. to send data ?
·
QUESTION 2:
·
Could someone please tell me how I would go about hooking up the propeller
To do this ? What object should I use. And/or what circuit connections should
start with ?
·
What would be the easyest way to send the databits?

Thanks for any help you can offer,
-Areal

I have a tree growing out of my head, but

what do you expect ? I'm a programmer.

Well,· I just say that this looks very similar to the things I was using from Sparkfun that didn't work out for me...· But, if they did work, no you don't need the Holtek chip, just give it a serial input and take serial output... But, you probably will need to do error checking...

Thanks Rayman for the help, it must have been a dumb question [noparse]:)[/noparse]

It's tuff being a novice, it takes allot of time to figure out simple
things, but I must say that I've found the Propeller chip to be
a very high quality solution. I think it's the #1 best chip in it's class.
It's been easy for me to learn, relative to other things I've tried.

I just wish I was making more progress in learning electronics,
It's been hard to learn MCU programming and basic electronics
at the same time.

It's a slow process, but at least, I'm learning.

Thanks again for trying to help me, and have a Happy New Year to everyone.

I don't know that it's a dumb question, though perhaps not specific enough. I'm not a Prop guy yet, so I can't say anything about code. I do share the concerns about those RF modules you're using, though. They do look quite a bit like the cheap ones that Sparkfun sells, and I think that you get what you pay for there. If I were you I'd work with those enough that you know whether or not they're reliable before you go too far on the rest of this. You may wind up using different modules.



I've had quite good luck with the Parallax 433 MHz modules as well as with XBees. I did eventually get the Sparkfun ones to work reliably, but only sitting right next to each other with well matched antennas. I learned a lot, but they simply weren't useful for an end product.

I'm using the Sparkfun Bluetooth module and it is perfect out to about 15'. Beyond that it still works well, but not perfect...
