• RE: Request Value from Node

    @soloam looks like you should be able to use mGetCommand and check for C_SET / C_REQ.

    I am using the pulse power meter but I didn't use any dummy variable. Also the controller plays a role too.

    @neverdie that is a nice pattern. I found that these things need time to draw. If anyone has a DXF file, I would love to try it.

    It is checking if it is a V_VAR1 message, the other messages use different variable types

    About 35 minutes after I reset the node, it started reporting again (without any other changes). I have no idea what caused it to start working.

  • RE: ToF for scanning doesnt work as desired

    @isaac-ng said in ToF for scanning doesnt work as desired:


    I've not used this particular sensor, but judging from the datasheet it uses IR led illumination and has a 42 degree field-of-view (http://www.st.com/content/ccc/resource/technical/document/datasheet/c4/11/28/86/e6/26/44/b3/DM00112632.pdf/files/DM00112632.pdf/jcr:content/translations/en.DM00112632.pdf, chapter 2.10.1).
    It probably 'averages' the distances measured withing its field-of-view, causing a gradual transition from distance 1 to distance 2.

    If you really need a step response in the measured distance you'd likely need a sensor with a very small field-of-view, e.g. a laser bundle.
    On the other hand, the point with the maximum slope in the transition from 1 to 2 will probably be very close to the actual step in your shape.

  • RE: Soft WDT reset on ESP8266 RFM69 gateway after find parent

    Well... kind of. Noise on power rail could also cause other problems too. I suggested the ceramic as it helps filtering the high frequencies in case your phone charger voltage is not very clean

  • RE: What did you build today (Pictures) ?

    @mickecarlsson except I have not yet tested the new things on the back (signing and extra flash) the boards are working. I will try to test the last things before May is over and the publish.

    If you want to order I can offcourse email you the Gerber's but on your own risk.

    My first experience with the board is that it's performing better than Rev 9 with the new position if the hardware. Also the ground plane helps.
