    Beautiful, this is exactly what I'm looking for and relatively at affordable price. Also it would be very nice if one of the IO pin can be configured as serial port, only RX pin will be enough. It will make the the measurement correlation even easier with readable text from serial along with the IO 0/1 state.

    how come there is no recording / information about the instant voltage and energy (e. g. kWh)?
    I assume that the power supply does not provide a perfectly stable voltage (eg when under heavy load), hence this will affect power consumption, no?
    And how to interpret the charge information?

    • @NordicSemi
      @NordicSemi  Місяць тому +1

      Charge measures the total amount of electric charge passing through your circuit (Q = I*t). We cannot accurately measure the energy as like you say, the voltage is often fluctuating, but the charge measurement which is less dependent on voltage can still help you calculate how fast a battery will be depleted when you know it's capacity rating. The PPK2 is first and foremost a tool to let developers inspect the current consumption to fine tune sleep modes, peripheral usage etc, but we will report your query back to the developer team.

    This is a really nice tool, congrats to Nordic team! We've been developing a nRF5340 product since early engineering samples, and will be happy to use this. One question: does anyone here know what software suite was used to develop the graphic analysis tool? I'm tempted to guess Qt, but the speed at which the 100kps data set flows on screen is a bit too good for what I’ve seen on that platform.

      They have public repository for the software: github.com/NordicSemiconductor/pc-nrfconnect-ppk

      As @WisseSpring already wrote, we are using Electron and more concrete for the charts we are using Chart.js. www.chartjs.org But, yes, it is a lot of data to process, so we spend quite some effort to optimise handling that data to make the UI more responsive.

    I have a question. Basically I would let PPK2 run for couple of minutes with a DUT connected to it. PPK2 provides 5V and DUT consumes about 60 mA. The results that I am receiving is in "REAL-TIME" window, however, after few minutes the application tends to freeze even though the power is still being delivered. I wonder if there is something that I should look out for in order to prevent this behavior? I could run more tests on different USB ports, different USB cable, even consider adding an additional one for more power (even though DUT only consumes 300 mW).

    When using as an ammeter mode, am I correct to assume it would act as a multimeter/current meter? Where I could measure the inline current of a wire at any point of the circuit as long as the wires will be connected in series in Vin / Vout of the PPK2? I plan to measure and test a few signal currents coming in / out of an IC.

    • @NordicSemi
      @NordicSemi  Рік тому

      Yes, it acts as an amperemeter (current meter) in ampmeter mode, and you can indeed plug it in series of the circuit you're measuring.

    • @losaminos59
      @losaminos59 Рік тому

      @@NordicSemi But do I still need to connect the ground pin of the PPK2? Unlike the traditional multimeter that is floating when measuring inline currents.
      I wonder what would happen if I left both the ground pins (left pin of Vin and right pin of Vout) not connected to anything?
      Something like this: Opamp output pin -- PPK2 Vin (ammeter mode) -- ESP32 ADC pin, to measure the incoming current to esp32.

    I have a question. Can i measure current consumption of 12v device? Im designing a product with 12v and buck converter i want to see how good my buck. I don't want to damage my unit so i have to ask before proceed

    • @NordicSemi
      @NordicSemi  Рік тому

      We do not want you to damage your unit, so good you asked. The supported device under test (DUT) voltage for the PPK2 ranges from 0.8V to 5.0V. So no, you can not measure a 12V device. You can see the user guide for more details: infocenter.nordicsemi.com/topic/ug_ppk/UG/ppk/PPK_user_guide_Quick_start.html?cp=10_10_3

    i have selected the ppk2 in the Power Profiler app, but it stills shows "instructions" and doesn't show any other buttons to do anything with the device.
