LP-EM-CC2340R53: [BLE 6.0 CS DKC] use one pin to control two Additional RF GPIO Signals

Part Number: LP-EM-CC2340R53
Other Parts Discussed in Thread: SYSCONFIG

Tool/software:

Hi TI

*SDK version: 9.11.00.18 ,example: key_node.

Because the pins we developed were not sufficient.,now  I want to use one pin to control two Additional RF GPIO Signals.Below is my setup.

I wonder if my setting is reasonable? What is the logic behind this setting? If it is not reasonable, how will I achieve my requirements??

  • Hi Peisheng,

    The logic behind PBEGPO2 and PBEGPO3 usage is described bellow. 

     

    In your case, even if a single bit is enough for the muxing, sysconfig will ask for two. The project won't build with with DIO14 as output for PBEGPO2 and PBEGPO3. What you have to do is to configure another unused DIO as output for one of them. Then you can choose the Antenna Muxing Bitmap corresponding to your hardware configuration.

    Here is a table with the values you can use with your configuration: 

    A2 Antennas muxing bitmap A1 PBEGPOX used
    X 1 0x4 X  0  PBEGPO2
    X 0 0x1 X 1
    1 X 0x8 0 X PBEGPO3
     0   X  0x2  1  X

    Kind Regards,

    Romain
