RF12 module need to convert some C to Basic

[davewanna]

I knew I was in above my head, and would do something stupid like try to re-invent the wheel. Oh well, at least I'm learning..

To counter that last statement though, would you believe I took "ORed" as "O-Red" and thought it was some C statement I didn't know about.. Really quite obvious now... stupid me.

I think I will just keep re-inventing the wheel until it's almost as good as the one we got now, then chuck it out and go with the tried and tested. At least by then I might know more about the module, and might have more luck trying the shiftout commands...

Hi davewanna

at the end; what about your project.

Are you satisfied about the RFM12.

I have just ordered some of that modules to make some RF trial; as I'm a novice in RF and SPI interfacing.

I have in plan to use this module with a 16F877 just to make experience before use it on a real project.

After reading the full tread, I have now a gray view of the problem that I will encounter to make the RF connection working. From your experience and your point of view, do you have any helpfull suggestions about PBP and the RFM12 module interfacing?

Ciao

Leo,

To be honest was never able to reliably transmit data. There were many many errors.

I have since found out a few pieces of information that I have not yet had a chance to try. Firstly, do not use the onboard osc output to run your MCU. Make sure the osc output is switched off. Apparently it creates noise in the transmission.

Also the setup is crucial, there is a lot of trial and error needed to get the settings right.

There is a lot of very valuable information here Most of the code is in C, but there is a forum, and a lot of information related to setup that you will need.

The datasheets will need to be read many many times.

I have some code that uses PBP's SEROUT commands to communicate with the RFM12, and currently it kind of works. I would suggest you try write it yourself, as you will get a much better understanding, but let me know if you really need it. It might even give me the kick I need to have another look at it.

Cheers

Hi Dave,

I need help about the SPI interface because I never used before.

Looking at the tread is difficult to understand the way to send data to the RFM12. I would understand clearly the PBP way to send data to the RFM12 module.

This evening I will made some trial, following this tread and I will tell you the results.

Thanks in advance for you kindly availability.

My God, Dave, that's brilliant ! That exactly describes the HUMAN LEARNING PROCESS ! I have never seen it put just that way. I really mean it, Good Job.
