Help with CC1100 RF Modules.

[charudatt]

Hello Ron,

I am very happy to inform you that I finally got the modules (One to tx and the other to Rx) to work.

There were some problem with the MCSM1 and MCSM0 register which I corrected. removed Manchester coding and incorporated a VCO calibration check, which you had disabled. After doing all these changes , i started getting random results at the receiver end, then I added a few delay in between the Buffer fill and just got the modules to work exactly as I wanted.

Oh god massive modules and adventure guaranteed.

There are still a few glitches (even after getting it to copy the write bytes) , which i plan to solve them myself.

I have yet to get the SO pin going high after a good packet is received. don't know why that is not happening. As a result I have to keep polling the RX_Buffer every time to see if i have Rx any data in it.

This is the start of my adventure and I sincerely thank you and Joe Desimone for taking time out and trying to solve my problem.

Now I shall play arround with the registers (value) and see the changes in the modules.

Supposedly, when the CS goes high (deselect), SO should become a standard output. If you have not selected packet protocol, then this will not work. I have it working quite well with GDO0 as the valid packet flag. I have not tried GDO1.
