Part Number: TIDA-01212
Other Parts Discussed in Thread: CC1310,

Hello Sir,

I am working on the TIDA-01212 only the part of IRDA,  my hardware is cc1310 launchpad and i use sensor controller studio to work on the software, HCACapTouch_IRLED_7bits.scp

from

the task of the txirled have two part , one of receiving and one of transmitting ,

i have skipped the part of RX, and i have set input.enable to "1" so that to test the TX part,

however, i cannot get any signal from the IO 29 ,

thanks if you can help

    Jeff,

    in general, two things may go wrong: HW or SW. A few things are still unclear to me, so please confirm:

    1. you do not have any IR LED + Resistor connected, right?
    2. you just connect your oscilloscope to the DIO29 to check the signal, right?
    3. Did you comment out the RX part of the code only (e.g. only the while (k < 7) loop and the timer0stop() line afterwards)?
    4. what is the CC1310LP revision you use (e.g. Rev1.xxx)?
    5. what is the voltage level you measure on DIO29 and does it change over time at all?

    Regards,

    Milen

    Jeff,

    i just tested the code on a CC1310LP and it works: i can see a Pulse train on DIO29.

    I did the following:

    1. in the SCP code, as you likely did to enable the TX part of the Task:

    // END of RX code

    input.enable = 1;

    2. I selected the TXIRLED task in the Sensor Studio for Task testing - i think that's your problem!

    As we have 3 tasks the default task test is the CapTouchButton - so that will not work.

    You need to select the TRXIRLED task yourself and then debug.

    3. You need to click on the blue "play" button to start the code.

    That should be it!

    Please, confirm that this solved your problem!

    Thanks,

    Milen
