Giriş

We have four items that we need to test:
A) the main integrated circuit (IC),
B) a level shifter,
C) solar charger,
D) cellular modem.


  1. Program the board with the code sleep_test_v2.cyprj.
    • Program the board with the code sleep_test_v2.cyprj.

    • Set a multimeter to the uA setting.

    • Make sure the probes are in the correct ports to measure amperage.

  2. Connect the red probe to the negative terminal of the board.
    • Connect the red probe to the negative terminal of the board.

    • Connect the black probe to the negative terminal of the battery.

    • Connect the power terminal of the battery to the power terminal of the board.

    • Using alligator clips make it easier to complete the circuit.

    • Press the reset button on the board. You should see the reading on the multimeter go to 5 mA then to around 20 uA.

  3. Now plug the battery as you normally would into the board. Change the multimeter to the DC voltage setting. Put the black probe on a negative terminal of the board.
    • Now plug the battery as you normally would into the board.

    • Change the multimeter to the DC voltage setting.

    • Put the black probe on a negative terminal of the board.

    • Put the red probe on p3.7.

    • There's a few places to check p3.7. A smaller diameter pad closer to the chip and then one of the bigger pads in part of the group of six pads closer to the cell module.

    • Press the reset button on the board. You should also see a blue LED when you reset the board, it quickly turns on then off).

    • The TX pin (p3.7) must toggle from logic high (means the voltage should equal the battery voltage).

    • To logic low (meaning the voltage should read 0).

  4. Just a male-male jumper wire to connect the XBEE pins 2 and 3. Put the black probe on a negative terminal of the board.
    • Just a male-male jumper wire to connect the XBEE pins 2 and 3.

    • Put the black probe on a negative terminal of the board.

    • Put the red probe on p3.6.

    • Press the reset button on the board. You should also see a blue LED when you reset the board, it quickly turns on then off).

    • The TX pin (p3.6) must toggle from logic high (means the voltage should equal the battery voltage).

    • To logic low (meaning the voltage should read 0).

  6. Put all the appropriate jumpers on the Open-Storm board. On the board, turn the small screw clockwise all the way until it stops. Then turn it back a quarter turn. This is what controls at what voltage the solar charger activates. Plug in a battery that is not fully charged into the battery input terminal on the Open-Storm board.

    • Plug in a battery that is not fully charged into the battery input terminal on the Open-Storm board.

  7. On the DC power supply, set both knobs to 0, for both current and voltage. Connect a battery. Use a battery that is discharged to a voltage below 4.2 volts DC Connect the power supply to the solar panel charging input terminal on the Open-Storm board.
    • On the DC power supply, set both knobs to 0, for both current and voltage.

    • Connect a battery. Use a battery that is discharged to a voltage below 4.2 volts DC

    • Connect the power supply to the solar panel charging input terminal on the Open-Storm board.

    • Turn the current knob to about 60 degrees.

  8. Slowly sweep the voltage knob to 4.5V. You should see a light green LED on the Open-Storm board. Turn the switch to see amperage on the display. It should read about 0A.
    • Slowly sweep the voltage knob to 4.5V.

    • You should see a light green LED on the Open-Storm board.

    • Turn the switch to see amperage on the display. It should read about 0A.

  9. Turn the display back to voltage. And continue turning the voltage knob to 14V. Switch the display and you should see 0.15A. The green light on the board should be brighter.
    • Turn the display back to voltage. And continue turning the voltage knob to 14V.

    • Switch the display and you should see 0.15A.

    • The green light on the board should be brighter.

  10. Ensure you are using an activated SIM and working cell module. Plug in a micro SD card, an activated cellular modem,  antenna, and a battery. Connect the programmer to the computer and then to the board. Then program the Open-Storm board with the perfect-cell program.
    • Ensure you are using an activated SIM and working cell module.

    • Plug in a micro SD card, an activated cellular modem, antenna, and a battery.

    • Connect the programmer to the computer and then to the board. Then program the Open-Storm board with the perfect-cell program.

    • Let it run the perfect-cell code for at least 3 minutes. Then disconnect the programmer and then the battery from the board.

    • Remove the SD card, plug into an SD reader.

    • Plug the SD reader into the computer.

  11. You should see a file labeled Modem.txt. Open it. Confirm the board is writing to the SD card.
    • You should see a file labeled Modem.txt. Open it.

    • Confirm the board is writing to the SD card.

    • "OK" indicates a response from the cell module.

  12. Reinsert the micro SD card into the Open-Storm board. Reconnect the battery. Take the board/battery to an area that has a good cellular signal. Check to make sure we are receiving data on our database (e.g. battery voltage). Confirm cellular activity on the provider (Twilio) network.
    • Reinsert the micro SD card into the Open-Storm board. Reconnect the battery.

    • Take the board/battery to an area that has a good cellular signal. Check to make sure we are receiving data on our database (e.g. battery voltage).

    • Confirm cellular activity on the provider (Twilio) network.

    • If a board passes all of these tests, it is ready to be installed in a node!
