RTOS/TIDA-00756: TI RTOS version for TIDA-00756

Part Number: TIDA-00756
Other Parts Discussed in Thread: CC2650, CC2652R

Tool/software: TI-RTOS

Hi Ti team,

What is the TI-RTOS  version we can use for TIDA-00756 ?

Regards,

Walter

  • Hi Walter,

    The firmware was developed using TI-RTOS 2.14.03.28.  If you want to make modifications to the existing firmware refer to the build instructions given in the read me file in the TIDA-00756 firmware installer.  

  • Hi Guz,

    Thanks.

    We are currently using latest zigbee SDK (simplelink_cc26x2_sdk_2_20_00_36 or simplelink_cc26x2_sdk_2_30_00_34 ).
    Do you think it is possible to integrate the TIDA-00756 firmware to these SDK instead on working on older SDK (TI-RTOS 2.14.03.28)?

  • Walter,

    Looks like those SDKs you mentioned do not support CC2650.  From this link, you can use SDK 2.21.01.08.  However, you would have to port the TIDA-00756 application code to that newer SDK.

  • Hi Guz,

    Thanks for your response.

    Actually, we want to port to latest zigbee simplelink_cc26x2_sdk_2_30_00_34. Is it possible?

    For hardware, what will be the needed change to use this reference design for smoke detector (stand-alone).
    1. trans-impedance amplifier design?
    2. sensor?

    That SDK is for the newer CC2652R multi-standard device.  I doesn't support the CC2650.

    It would require a full re-design.  TIDA-00756 measures CO using an electro-chemical CO sensor.  The mechanism for measuring smoke is entirely different using either photoelectric or ionization method.  Please take a look at our Smoke and Heat Detector end equipment page.  You can find several resources there.

    Note, back to your original question, if you end goal is smoke detection using ZigBee for communication, then TIDA-00756 will not help you much & a new design would be needed. At that point I would suggest picking the latest ZigBee Simplelink Radio (i.e. CC2652R) using the latest SDK.

  • Hi Guz,

    Our plan is to change the CO sensor into a photo electric sensor.

    The reference designs in Smoke and Heat Detector page uses internal OA which the cc2652 do not have. So, we plan to use discrete TIA.

    Also, with the change of end part from COSensor to PhotoDiode, will the circuits will be the same or is there needed changes required in order for cc2652 to pick up the same output converted from the COsensor to Diode.

  • Hi Guz,

    Any response?

  • Walter,

    The parameters of any transimpedance circuit need to be tuned to the signal being measured. The TIA design included in TIDA-00756 was tuned to the particular electrochemical cell used for CO sensing. There is also other logic included to test the sensor operation. Neither of these would work "as is" for the photodiode used in a photoelectric smoke sensor design. Keep in mind that you also need a LED and corresponding driver circuit for the smoke sensor.
