CC1101: CC1101. Read & write registers in a single chip.

Part Number: CC1101

Hello,

I am very novice and I need your help. I have a simple I.C. CC1101 and I want to be able to read the registers and record them again, after modifying them. I used this scheme:

 



Using the SmartRF Studio 7 program and a CC Debugger directly connected to the chip. But the software does not detect the chip and the light in the CCDebugger is red.

What circuit (schema) and software should I use to read and write records directly on the chip without any evaluation card?

Thank you in advance.

    The schematic is missing in your post.

    Without knowing anything about the RF module I'm missing some information. Are you able to monitor the SPI lines when you attach the debugger to the module and verify that this is correct compared to what is covered in the UserGuide?

    Hi,

    I am confused.

    I just want to "copy" the records from one chip into another. I have placed an IC in a Z.I.F. and I have connected it directly to the CC Debugger according to the above scheme.

    In this way, I intend to read the records and save the hex image. Then, after modifying some record, to record (flash) that image on another chip.

    B.R.

    - The registers in CC1101 is RAM meaning that they loose their content when you remove power. Setting the registers have to be done from a MCU.
    - If you use a Z.I.F, does that mean you haven't connected anything else to CC1101 than the debugger? That will not work. You have to connect a xtal, the 56 kohm resistor etc to be able to connect to CC1101

    Thank you. I was really wrong. I'll start with the development boards recommended by TI.
