Dear support,
I am working on the people counting demo and want to operate two sensors simultaneously. Therefore, I am making use of time-multiplexing and an external trigger.
I want to use Arduino to supply a voltage of 3.3V to the SYNC_IN port (J6 pinnumber 9) of the sensors alternately to achieve the time-multiplexing.
I am making sure that in the configuration "frameCfg 0 1 128 0 30 2 0" and that the SYNC_IN Periodicity is larger than the Frame Trigger Delay plus the Frame Periodicity, as explained in http://e2e.ti.com/support/sensors/f/1023/p/639919/2479216?tisearch=e2e-sitesearch&keymatch=sync_in#2479216.
My questions, however, are:
1. Am I missing something? And is it safe to just execute this experiment with the aforementioned steps taken without blowing up the IWR1642BOOST?
2. Is it needed to add or enable a pulldown resistor before connecting to the SYNC_IN pin or is it already enabled internally?
3. If it is necessary to enable, how and where can I do this in the software related to the People Counting Demo?
Kind regards,
Mike
