The plan is, start with this website(there's a link here):
Get this to work using the full SimpliciTI stack, and see what I really need. If I can get this to work on a platform it plays natively with, I should be able to port this to the RFDuino.
So, from the left we have a TI MSP430 Launchpad, next to that a CC2500 module broken out onto a Schmart board, and finally the RFDuino. End product will be on a PCB, may or may not go with the surface mount RFDuino. Power usage may be low enough to use a coin cell, which would be very cool.
I've picked the 2500 up a few times over the last 6 months, this post will help me keep track of my progress, I have so many bookmarks it's hard to find the details anymore. I've tried SPI with the CC2500 to an Arduino. SPI isn't plug and play. I could only get as far as updating registers.
Lots of sensitive timing issues, most recommend a scope. I think some of the issues I've experienced trying other peoples code is the microcontroller speed.
Abandoning simpliciTI (Again). This is for people with 40 hours to kill, not weekends.
I think I'm getting closer just using SPI. IOCFG0 is one important factor in the variability of code you find. The "sheet" for my CC2500 board refers to a couple of GDOX pins as general use. So you think great, don't need to hook those up. Turns out GDO0, is responsible for notifying your code that a packet has been received. But, only if you set the IOCFG0 register with the correct value(and there are many to choose from). Most likely 0x06 is what we want here.
