    Wich board do you use in arduino? I

    Not sure what you're asking.



  • @neverdie I mean this:
    0_1517742775930_ArduinoBoard.png
    When I use Generic nRF51 or something else, the onboard LED turns on and doesn't turns off. When I use Waveshare BLE400 the sketch works as usual

    @tiwo85
    I use this:
    0_1517752283964_arduino_board_type.png
    You download it from @d00616 on github.



  • @neverdie do you have a working example sketch. I try the example sketch from the 10years pir sensor an d modify a little bit, but it doesn't work. The sketch awake every 5 minutes and send the state from the pir and that's it.

  • @neverdie thank you. I made this sketch work. But I need to get work interrupts. I use your code for the am612, but it doesn't work. Then I use the example from Redbear labs "Example interrupted" to turn on the led when p0.02 is high. I use Mysensors library and set My Core only. Then it runs. But when I try to integrate Mysensors routines "presentation" etc. And disable "my core only" , then the interrupt doesn't work.

    // SUMMARY: This demo sketch runs on the AM612 PIR v607 PCBto transmit battery voltage (heartbeat) and motion detections to a MySensors gateway using MySensors protocols.
    
    // Note: because this is a passive node, node ID must be set manually to a unique sensor node ID:
    #define MY_NODE_ID 143  // Passive mode requires static node ID
    
    //#define MY_CORE_ONLY
    
    #define MY_PASSIVE_NODE
    
    #define MY_RADIO_NRF5_ESB

    @tiwo85 I suggest you start a different thread on your interrupt problems, since that's really a separate issue and not specific to this hardware.



  • Hi,

    I like to buy this board and your AM612 breakout pcb through hardware.io.

    But first I have few questions unfortunately I couldn't find the answers here in this thread/forum.

    1. I assume this board has to be programmed via the 10pin box header. How can I connect it to my computer? I think there is some adapter or similar required? Any selfmade options available? In this thread I saw that it should be possible to program this device via the Arduino IDE?

    2. Can I mount the following sensors at the same time without space conflicts:

    • Motion PIR (AM612breakout)
    • Temp + Humidity
    • Light
    1. Does this board have some free digital pins for door contact and or relais? (if yes, how many?)

    2. (Optional) I think there are no MISO/MOSI/... pins for connecting a RFM69 module?

    I don't like to use the battery option. I will power the board via power supply. Can I connect a 5V power supply to the battery pins or what is the best option?

    Thanks in advance.

    Hello @ehome

    1. it is based on an arduino pro mini (NModule board, don't forget that this is just a shield for NModule) , so you program the arduino pro-mini, usually using an FTDI adapter. You should find plenty of explanations online.
      For programming bootloader/fuses, you can use and arduino nano with the ArduinoISP sketch: MOSI=>MOSI, MISO=>MISO, SCK=>SCK and SS (pin 10) of nano to reset pin of the pro mini. Here also you will find plenty of examples/videos etc online.
      Start with reading the page about NModule:
      https://www.openhardware.io/view/364/NModule

    2. In theory yes if light sensor is on the AM612 breakout. I will test this configuration next week and confirm to you that it is working before you order the board. If you don't hear any news about that before the end of next week ring me a bell here as it probably means I forgot 🙂

    3. You will use one of the external interrupt pins (pin 3) for the PIR sensor, so you will have one left (pin 2). If you don't use the leds there are 3 other input pins available on the NModule connector (A1,A2,A3, you can use them as digital inputs too), on battery powered sensors it needs pin change interrupts, but as you are using a power supply it won't be a problem.

    4. No you can't connect a RFM module, NModule is only for SMD NRF24 modules

    5. You should connect power to RAW and GND pins on the NModule connector. The best is to use AMS1117 regulator to get the 3.3V, it's probably overkill for your usage but it's very stable and will filter the noise of your power supply much better than the XC6206 (which more suitable for a li-ion powered node). In addition you will be able to use a power supply up to 12V



  • @Nca78 many thanks for your answer. Maybe may question was a little bit too vague. I didn't mean the NMODULE board. I was speaking about the NRF51xxx board from @NeverDie

    These are shield made to work with the NModule. For the same sensors I think @NeverDie has what you need in NRF5 versions, so ask him on the right thread 🙂
