3 SW Modifications for CC2530 SoC + CC2591 PA/LNA combination Below you can find the SW modifications needed when running the current TI-MAC (v1.3.0) / Z-Stack (v2.2.0) software releas on a CC2530 SoC in combination with a CC2591 PA/LNA. Later revisions of Z-stack or TI-MAC will h
ave the additions already included in the distribution. For CC2590 PA/LNA urs, plea contact TI support for more information.
3.1 CC2530-CC2591EM 2.0
CC2530 P0_7, P1_1, and P1_4 GPIO pins are ud to control CC2591 mode of operations in order to comply with ver 2.0 of the CC2530-CC2591 combo board EM. They are connected to CC2591 HGM, PAEN, and EN respectively. CC2591 is enabled by turning on the compiler switch, HAL_PA_LNA. This compiler switch should be added at the beginning of
“hal_board_cfg.h”. It is to be noted that once the HAL_PA_LNA compiler switch is turned on, the above mentioned pins are configured to be ud ONLY for the control of the CC2591. The simple block diagram below shows the interconnect between the CC2530 and CC2591.

In order to change the pin assignment of the control signals, the ur must be aware of the following:
1) P0_7 can be moved to any GPIO pin, and the macros below HAL_PA_LNA_RX_LGM() and HAL_PA_LNA_RX_HGM() must be modified accordingly.
2) P1_1 and P1_4 are a subt of GPIO pins (only P1.0-P1.5) that can be configured to support special RF obrvation output control signals. PAEN and EN of the CC2591 are directly controlled by the signals via the radio core logic of the CC2530. See the CC253x Ur’s Guide for more details. The ur only needs to adjust the OBSSELx registers to change the pin assignment.
When the CC2591 is enabled, only LED1 is available to the urs on the SmartRF05EB board due to the shared GPIO pins.
Two (2) APIs are provided to lect between CC2591 RX LGM and RX HGM. CC2591 is initialized to RX HGM in HAL_BOARD_INIT().
3.1.1 HAL_PA_LNA_RX_LGM()
饮料的英语单词Description
This macro lects CC2591 RX low gain mode. To u this macro, “mac_radio_defs.h” must be included in your application.
Macro Definition
#define HAL_PA_LNA_RX_LGM() st(P0_7 = 0; )
Example
In your application, add HAL_PA_LNA_RX_LGM() to switch to RX LGM.
#include “mac_radio_defs.h”
…
/* Switch PA LNA to LGM */
HAL_PA_LNA_RX_LGM();
3.1.2 HAL_PA_LNA_RX_HGM()
Description
This macro lects CC2591 RX high gain mode. To u this macro, “hal_board.h” must be included in your application. This macro should be added at the beginning of
“hal_board_cfg.h”.
Macro Definition
#define HAL_PA_LNA_RX_HGM() st(P0_7 = 1; )
Example
In your application, add HAL_PA_LNA_RX_HGM() to switch to RX HGM.
#include “mac_radio_defs.h”
…
/* Switch PA LNA to HGM */
HAL_PA_LNA_RX_HGM();
3.2 Special Note for Z-Stack (v2.2.0) urs
If you u Z-Stack (v2.2.0) relea, additional software changes are required. For CC2590 PA/LNA urs, plea contact TI support for more information.
3.2.1 hal_mac_cfg.h
In “hal_mac_cfg.h”, change the RSSI offt defines to:
/* CC2591 RSSI offt */
#define HAL_MAC_RSSI_LNA_HGM_OFFSET -9
#define HAL_MAC_RSSI_LNA_LGM_OFFSET 4
3.2.2 mac_radio_defs.h
In “mac_radio_defs.h”, change the macRadioDefsTxPowerTable[] table to:
#if defined (HAL_PA_LNA)
const uint8 CODE macRadioDefsTxPowerTable[] =
{
