Pin Configuration Changes

The Anaren CC2530 based modules follow the ZNP pinout and use P1.3 to control the EN signal of the PA/LNA. This differs from other TI reference designs that use P1.4 for the EN signal. If compiling your own code to use on an Anaren module with this pin configuration then you'll need to make the following changes. This does not apply when using the firmware loaded on the modules already, this is only if you are writing your own firmware to run on the CC2530.

To use P1.3 to control the PA/LNA, you'll need to change the file mac_radio_defs.c

In the method macRadioTurnOnPower(void): //OLD /* P1_4 -> EN (LNA control) */ //   RFC_OBS_CTRL1 = RFC_OBS_CTRL_LNAMIX_PD_INV; //   OBSSEL4       = OBSSEL_OBS_CTRL1;

//NEW /* P1_3 -> EN (LNA control) */ RFC_OBS_CTRL1 = RFC_OBS_CTRL_LNAMIX_PD_INV; OBSSEL3      = OBSSEL_OBS_CTRL1;

If you were using P1.3 for USART1 then you will need to modify that code as well.

Note: you don't need to do anything with CC2591_COMPRESSION_WORKAROUND; that isn't needed in this design.
