CC2652P: RF Switch with 2 Antenna Pins

Akhilesh Premkumar

Part Number: CC2652P
Other Parts Discussed in Thread: SIMPLELINK-CC13X2-26X2-SDK, SYSCONFIG

Hello,

We are trying to configure the CC2652P with 2 RF Antenna Pins(instead of the sample 3 pins for 1352P-2 using SKY1337).

The RF switch we are using is slightly different as in we have only 2 pins for PA mode and normal, but the pins follow the reverse truth table( i.e. 0 is active). What changes are needed to support this, I'm using the zr_light_CC1532P-2 sample. The truth table comparisons for reference

Thanks

Hi Akhilesh,

Which SIMPLELINK-CC13X2-26X2-SDK version are you using? I recommend you use version 4.10 and select "Use Custom Board" inside SysConfig, then use a custom rfDriverCallback to configure your antenna switch truth table. Here are some resources for your reference:

Hi Akhilesh,

Since SDK 4.10, using SysConfig, you can select the number of pins used for the RF switch:

SysConfig, will also let you specify the callback to use. Please review the content of the file ti_drivers_config.c [generated by SysConfig] (especially the sections marked "PLEASE READ THIS") to see how to right the callback functions.

I hope this will help,

Kind regards,

I am having same number of pins in my custom board difference is only pin numbering. Launchpad uses 29 pin as PA but I'm using DIO7 as PA. So my question is what specific changes i need to do in rfDriverCallbackCustom function.
