RFM22B HF module working with PIC ?

[crocu]

Hello

I would like to get RFM22B module with a PIC in order to send and receive text or commands over HF.

I'm using C18 and (or) XC8 compiler with PIC, i did not find example of use for these modules.
Has someone an experience or working code ?

RFM22B modules have many registers and i don't know how to start .
Your help will be much appreciated.

Many thanks,

Cant help with the software, but 400+MHz is considered to be Ultra High Frequency (UHF) . HF is 3-30MhZ

I've used the RFM12B modules with PICs. I think the interface is identical. I don't have C code, but the manufacturer, HopeRF, has code in C in their datasheet. It's pretty simple, mine worked first try.

Hello,

I'm still fighting against 2 x RFM22B S2 modules to get them working with a PIC. ( i use a 18F2620 )
I simply would like to get a working demo because i can't get communication working on these modules.

I've spend long time on the datasheet and on the Hoperf demo code without success.
I will really appreciate if someone would share a working demo code, ie sending a demo sentence 'Hello World' to the distant module.

Many thanks for your help,

Hi, crocu. There is a link to example code on this page: https://www.sparkfun.com/products/10153

Many thanks ccurtis.

However this code was already my base of work, actually I've tried to get inspired from that code ( it was written for Atmel µC ) but i think i was not able to port it for PIC properly , since it does not get transmission working from here.

It could be helpful if has a working for written in C18 or XC8 for PIC µC.

Many thanks
