Update – I found a bug today in the driver. Hi Dave and thanks for the code. Essentials Only Full Version. I’m kind of new to this. Thank you very much and I appreciate your intention to help others. It also turns out that I can not use the frame number directly to check for duplicates since the transmitting device is battery operated and only wakes up once every 15 minutes. If you’re familiar with using the PIC18, it shouldn’t be hard.

All the details, including a download link, are here: I wonder where I would have been today trying to wade through the the MiWi code.

Trying to implement a simple data transmition between two devices for an university project robot and a wireless hand-held device to monitor the parameters from the robot. Please post here if you’ve got any questions. All I wanted to see is ‘successful compilation’ with the tools I have.


Maybe someone has mrf24n40 to get this working on ATMega32? This is a small project running on the Explorer 16 development board with a 2. Forums Posts Latest Posts.

It may be a good starting place if you want to write your own code, or just understand how to talk to the MRF24J Don’t mrt24j40 me wrong, the MiWi stack is great but sometimes it is just so much easier to start with the basics when sending a packet from A to B is all you need. Now I read that you used C32 compiler for compiling your code.


I have set up one to send data and one to receive. Thanks very much for posting this. Hi Dave, The code is much simpler and easier to understand. Not much is changed in the actual driver rmf24j40. This was originally based on MiWi P2P v3. Forum Themes Elegant Mobile.

If you do get it working yourself, please post it here for micfochip to use! Same deal for interrupt lines IIRC. User Control Panel Log out.

I do know of one person microchipp said she was porting it to mff24j40 PIC18, but I don’t know how that came out. If No, then is it possible to compile your code with C18 compiler using different syntaxes or including more lib files which I may not be aware of. Would you mind posting the code as ported to the PIC24, so that other people using the PIC24 can start from your version? Again, thanks for the original code.


MRF24J40MA – Wireless – Wireless Modules – Wireless

Again, thanks for the code. This code is much, much simpler than MiWi P2P but it doesn’t have all those features, either. Do you mrf24i40 any simple code for PIC18? And my C knowledge is not to deep so i had never used some syntaxes used in this code. Can you post the changes you made? I also want to give the hardware SPI one more go since I havn’t got mjcrochip to work yet.

Simple driver code for Microchip MRF24J40 radio (now available)

However, the receiver side never receives anything. May I have your permission to add it to my website together with the PIC32 version? Rmf24j40 a new project stating PIC18f as a microcontroller in project wizard in C18 compiler. I realized that it should not be too hard now. Otherwise power back-flowed through that pin via a pull-up on the input I expect.
