couldn't find temperature sensor and zigbee

Other Parts Discussed in Thread: CC2538

Hi

Am using cc2538DK for my project.I am unable to find out the temperature sensor and zigbee in cc2538 board....

For temperature sensor, the following steps are to be done....

 SysCtrlPeripheralEnable(SYS_CTRL_PERIPH_RFC);

HWREG(CCTEST_TR0) |= CCTEST_TR0_ADCTM;

HWREG(RFCORE_XREG_ATEST) = 0x01;

SOCADCSingleStart(SOCADC_TEMP_SENS);

but exactly where the temperature sensor is there in cc2538 board?

could anyone suggest solution for this?

    Do you want to use CC2538 on-chip temperature sensor? If so, you can download software from http://www.ti.com/tool/cc2538-sw you will find the file adc_tempsens.c under cc2538_foundation_firmware_1_0_1_0\driverlib\cc2538\examples\adc\source

    Thanks for the reply...

    Yes I want to use it as on chip temperature sensor....I have seen the sample code 

    Is this temperature will work as room temperature?

    Is there any document for temperature sensor?

    Like accelerometer and light sensors are visible on smartRF06EB, am unable to visible the temperature sensor on cc2538DK....I have seen the schematic of cc2538 board but am unable to get it....

    Could you tell me the where is the temperature sensor on cc2538 board...... ?

    In cc2538DK, the data can be transmit/receive wirelessly using zigbee.....

    May I know where is the zigbee module on cc2538DK?

    which pins used for radio?

    The on-chip temperature sensor means it is embedded in CC2538 SOC so you won't see it on SmarRF06EB. You refer to CC2538 user guide at http://www.ti.com/lit/ug/swru319c/swru319c.pdf for details. The temperature sensor is not very accurate so it depends on how you define to work as room temperature. CC2538 is also embeded 2.4 RF transciver which means all TX/RX are controlled by internal registers.
