CC2500 Breakout/BoosterPack

[mblackm1 0]

Does anyone have a finished product with these boards any videos I really want to do something like to receive from a motion sensor for security system .this will be my first project

I Google'd and found this (I know its like 6 months old). http://lars.roland.bz/garage-door-opener-using-msp430-and-cc2500/

... and no, I am not stalking you.... :grin:

I finally got around to assembling the smaller stand-alone board. The problem I have is that the board does not program with the radio attached. When I remove the radio, programming completes successfully. Any idea why that would happen? I use the 0.05 header on the launchpad for programming. The board only has C1, C2, and R1 in addition to the microprocessor.

 

I double checked all connections. Perhaps the radio is defective?

I've soldered mine on to the Breakout boards but that's as far as I got sorry.

So I think I have figured it out. When resting the board on the launchpad header, the radio comes into close contact (~1") with the 12mhz crystal on the launchpad used for USB. The radio somehow causes interference and USB communication goes haywire. My workaround is to to solder a female 0.05 header to the board and a male 0.05 header to the radio, and to remove the radio whenever I need to program the board. I guess I could also make a cable to connect the board to the launchpad.

There are so many long tracks on LP, I am not surprised. They are probably acting as antennas.

How about adding a small shield (sheet of metal or PCB) between booster pack and LP on the debugger side?

I finally figured out why the board could not be programmed with the radio attached to it. I previously removed all jumpers between the two halves of the Launchpad, assuming that the 0.05 mm header was connected directly to the programmer. This was wrong. It turns out that the VCC jumper needs to stay on. Surprisingly the board could still be programmed with VCC disconnected -- I am guessing there is enough current leakage from other pins. With a radio module attached, and with the additional current that it needed, programming no longer worked.

 

To summarize -- when using the 0.05 mm programming header, keep the VCC jumper on. The other jumpers can be removed.

Yes, the VCC jumper is passed through the programming jumpers, so are the serial lines! This means that you can set the outmost two pins of the 0.05" (1.27mm) header to be swapped by using the jumpers.

Greetings,

 

I picked up breakout board at the store, I was wondering if there was a PDF/png version of the schematic for the cc2500 breakout board?

 

I found a image of the pcb layout http://forum.43oh.com/index.php?app=core&module=attach&section=attach&attach_id=1289 by no link to the schematic itself.  Is there a wiki page that I've missed.  If I can find all the info I'll start one ;D

 

Thanks all

Welcome to 43oh, fork. There is no wiki for the board yet. @@RobG should be able to post a schematic, if there is any.. it probably is just a .brd file. As far as I can see, if should be easy to trace the pins. Most of the board needs to be cut up.
