I have a problem with the CC2500. I am trying to interface the CC2500 with an external micro. The CC2500EM is attached to a SmartRF04EB. I have verified with a logic analyzer that the micro is putting the correct signals on the correct lines and that they are connected, as per the schematics for the SmartRF04EB, correctly to the CC2500. I have removed all of the zero Ohm resistors and the jumpers between the header and the USB IC. The problem I have is that when I connect the SCLK signal line to the SmartRF04EB, the SCLK signal disappears. If I remove the CC2500EM it still disappears. If I power down the SmartRF04EB the SCLK signal is fine and the SPI is operating correctly. I have two complete DK-CC2500 boards both with SmartRF04EBs and CC2500EMs and they both do the same thing.
I have read all of the documentation I know of, looked through these pages etc. I suspect that there is something further I need to disconnect but I have no idea what it is or where to find it. Does anyone have an idea what is wrong here?
There does seem to be something wrong with the Smart Rf04EB. I stuck wires into the Samtec Bd2Bd connector of the CC2500EM and everything worked fine. Its very strange but not too surprising. Consider this closed.
