Tws-434

demket

Since two days, I'm looking for examples about TWS-434 and RWS-434 for the propeller. What I found was about basicstamp.

My project, I'll send temperature information with multi pic using the TWS-434 or derivative of. And Prop'll get data with RWS-434 etc...

Is there any obex or sample?

Thanks

Hi Demket,

welcome to the propeller-forum.
I have no idea whar a TWS-43 and a RWS-434 are. if you haven't found anything with the keywords "TWS" "RWS" you should provide information what kind of devices this are and what kind of interface they are using.
In the microcontroller-world things are not that easy that you just type in the type-number and get plenty of google-hits for downloading drivers.

best regards

Stefan

Modules using the Nordic Semi nRF24L01+ are much more suitable, and Propeller code is available:

Low cost modules are available:

What about the preamble? it prevents conflicts for two or more transmitter?

And where should I add to a preamble byte?

See the nRF24L01+ data sheet. They are often used in wireless sensor networks, here is a simple example:

It's similar to your application.

hard to find around here. As far as I see, the only disadvantage is number of pins. it is quite good, except.

The driver in the OBEX does not work.

I used Leon's C code to make my own driver. There are a couple of different demos in this thread.
