CC1312R: How to configure CC1312R + CC1190 TI15.4?

Part Number: CC1312R
Other Parts Discussed in Thread: CC1190,

Hi team,

Here's the request from the customer:

Customer encountered difficulties in configuring CC1312R+CC1190. They can’t find “CONFIG_RANGE_EXT_MODE” in the SDK_cc13xx_cc26xx. "collector.syscfg” also has no PA and Related configurations of the LNA.

Refer to https://e2e.ti.com/support/wireless-connectivity/sub-1-ghz-group/sub-1-ghz/f/sub-1-ghz-forum/827042/ccs-cc1312r-about-enabling-cc1190-by-define-config_range_ext_mode?tisearch=e2e-sitesearch&keymatch=CC1312R%20CONFIG_RANGE_EXT_MODE# and https://e2e.ti.com/support/wireless-connectivity/sub-1-ghz-group/sub-1-ghz/f/sub-1-ghz-forum/897953/cc1312r-how-to-enable-pa-on-ti-15-4-stack/3345883?tisearch=e2e-sitesearch&keymatch=PA%25252525252525252520LNA#3345883, how to import specifically, and which files to import? The pins he had configured according to the hardware.

Could you help check this case? Thanks.

Best Regards,

Nick

Hi Nick,

Is it a commercial module, or a custom PCB?

Has your customer looked at that thread? https://e2e.ti.com/support/wireless-connectivity/sub-1-ghz-group/sub-1-ghz/f/sub-1-ghz-forum/899330/cc1312r-using-cc1190-with-cc1312

Else, the customer might have to configure a custom antenna callback and modify it according to the amplifier's truth table, as seen here: https://e2e.ti.com/support/wireless-connectivity/other-wireless-group/other-wireless/f/other-wireless-technologies-forum/1117703/cc1352p-launchxl-cc1352p-antenna-switching-callback

Arthur

Hi Arthur,

Here's the reply from the customer:

According to the second thread you given, cusotmer configured it as follows:

       GPIO_init();
        GPIO_setMux(Board_PALNA_LNA, IOC_PORT_RFC_GPO0);
        GPIO_setMux(Board_PALNA_PA, IOC_PORT_RFC_GPO1);

        GPIO_write(Board_PALNA_HGM, (hgm & 1));
}

This part of the code is placed before the "CCFGRead_IEEE_MAC" of the "appTaskFxn" function. It is
found that cc1312 does not start the PA during signal transmission.

In additon, customer also tested:

        IOCPortConfigureSet(Board_PALNA_LNA, IOC_PORT_RFC_GPO0,IOC_STD_OUTPUT);
        IOCPortConfigureSet(Board_PALNA_PA, IOC_PORT_RFC_GPO1,IOC_STD_OUTPUT);

It also did not start the PA.

Best Regards,

Nick

Hi Arthur,

May I know is there any update for this question?

At the same time he also tested:

IOCPortConfigureSet(Board_PALNA_PA, IOC_PORT_RFC_GPO3,IOC_IOMODE_NORMAL)

IOCPortConfigureSet(Board_PALNA_PA, IOC_PORT_RFC_GPO2,IOC_IOMODE_NORMAL);

None of them can achieve PA startup, and the total current is up to 30MA during wireless transmission.

Nick
