    I'm working on a gesture sensor connected to a Fanstell BT832 via I2C. It is a Sparkfun APDS9960 breakout I have had lying around for a while. Unfortunately I can't get my sketch to compile. It gives 'Wire' was not declared in this scope.
    Wire.h is included in the library and in the sketch. I'm using MyBoardNRF5 for an NRF52832. Using Arduino 1.8.3 on Windows 10.
    There is a wire library in:
    \AppData\Local\Arduino15\packages\sandeepmistry\hardware\nRF5\0.5.1\libraries\Wire
    Which I think is the one that this sketch should be using.
    Usually I can sort out the compile errors, but this one has me stumped.
    Anyone have any suggestions?

    @nagelc if you turn on "show verbose output during compilation+upload" in File->preferences you should get output telling which library the Arduino IDE has chosen.
    The following sketch:

    #define MY_RADIO_NRF5_ESB
    #include <Wire.h>
    #include <MySensors.h>
    void setup() {
    }
    
    void loop() {
    }
    

    Gives this result for me:

    Using library Wire at version 1.0 in folder: C:\Users\Micke\AppData\Local\Arduino15\packages\sandeepmistry\hardware\nRF5\0.5.1\libraries\Wire 
    Using library MySensors at version 2.3.0-alpha in folder: R:\Documents\Arduino\libraries\MySensors

      @mfalkvidd Thanks. The verbose settings show it using the sandeepmistry library.
      Wire.h works fine when I include it in my sketch. There is something about the way it is called in the Sparkfun library that fails to compile. I'll keep poking at it.


      Duh . . . Found the problem!
      I had left WIRE_INTERFACES_COUNT defined as 0 in MyBoardNRF5.h
      It has to be #defined to 1 or more, or the sandeepmistry library doesn't extern Wire.
      I looked at the SDA and SCL pin definitions in MyBoardNRF5.h, but missed setting the define for how many I2C interfaces were to be used.
      Change #define WIRE_INTERFACES_COUNT 1. Now it compiles as expected.

        This might be a silly question, but: there there a number of NRF5 smart watches available on Aliexpress, like this one. Would it theoretically be possible to turn that into a MySensors smart watch? If you had access to the programming pins, for example?

          @alowhum Usurping control of it by uploading code wouldn't be difficult, assuming access to the programming pins. However, taking control of the screen and making good use of it might be difficult

            yes it's doable, maybe not for those who are not smd friendly. And once opened it should be less waterproof :sweat_smile:

              @alowhum there is a whole "movement" of people who are trying to reprogram them. Key issue is openability (how hard is to open it)
              The last easily openable watches are based on nrf51822, but the good thing is that programming pins are easily accesable and even marked SWD/SCLCK.
              Search Ali for ID107HR and google for "roger clark smartwatch"
              I am yet to find a watch that would be both nrf52 based AND easily openable

                  Seems like there is hope then of accessing the screen after all. On http://www.rogerclark.net/arduino-on-the-id100hr-fitness-tracker/ it says: "Display: 0.49 inch OLED display (64×32 pixels) which uses the SSD1306 display controller"

                    Maybe someone here can figure out how to 3D print their own nRF52832 smart watch? i.e. one that's meant to be taken apart and put back together so that it's as good as new.

                      @neverdie read Issues section in Mark Cooks's repo referenced above. He's just committed a PR to support the display.
                      I need nrf52 to able to use Central role in my projects. For Mysensors nrf51 is pretty adequate if someone wants to create something like a wearable weather station :-)
                      Everything is in place.

                        @toyman Seems like it has a lot of potential as an awesome notifier/remote-control that's conveniently always with you. If you succeed in getting it to work, please do post a photo and let us know!

                          Note: to hack it you need a J-Link device:

                            So I made a version of script with MySensors library, it's not a final version and needs some cleaning and improvements but it seems to work well (I didn't test so much yet :)) and shows basic usage. Comments should be enough to understand what to change to adapt to your board. Current script is for my board:

                            • BUTTON_1 on pin 1, it's a hall sensor for door so no pullup and sensing on up=>down and down=>up changes
                            • BUTTON_2 on pin 3, push button with pullup and debouncing, sensing only on up=>down when button is pressed. At the moment it just makes some light blinking to show it's detected.
                            • led on pin 2.

                            I join the main script file and the MyBoardNRF5 files, for using with MyBoardNRF5 nrf51822. Files to include are described in the main script file, but don't forget to add a weak attribute in the WInterrupt.c file before the GPIOTE_IRQHandler so it can be overridden.

                            __attribute__ ((weak))
                            void GPIOTE_IRQHandler()
                            

                            On my Windows PC this file is in C:\Users[your user name]\AppData\Local\Arduino15\packages\sandeepmistry\hardware\nRF5\0.5.1\cores\nRF5

                            Main script file:

                            // Include app_gpiote and related files from NRF5 SDK 12
                            extern "C" {
                            #include "app_gpiote.h"
                            #include "nrf_gpio.h"
                            #include "app_error.h"
                            }
                            
                            // Files to include from SDK:

                              If you don't use an nRF5 board, you can ignore this file.
                              This file was part of the "My Sensors nRF5 Boards" board repository
                              available at https://github.com/mysensors/ArduinoBoards If you have
                              questions, please refer the documentation at
                              https://github.com/mysensors/ArduinoHwNRF5 first.
                              This file is compatible with ArduinoHwNRF5 >= 0.2.0
                              This file allows you to change the pins of internal hardware, like the
                              serial port, SPI bus or Wire bus.
                              All pins referenced here are mapped via the "g_ADigitalPinMap" Array
                              defined in "MyBoardNRF5.cpp" to pins of the MCU.
                              
                              As an example, if you have at the third position in "g_ADigitalPinMap" the
                              12, then all ports referenced in Arduino with 2 are mapped to P0.12. If you
                              don't change the "g_ADigitalPinMap" Array, the Arduino pins 0..31 are
                              translated to P0.00..P0..31.

                              This file is compatible with ArduinoHwNRF5 >= 0.2.0
                              This file allows you to change the relation between pins referenced in
                              the Arduino IDE (0..31) and pins of the nRF5 MCU (P0.00..P0.31).
                              
                              If you can live with addressing the GPIO pins by using the Arduino pins
                              0..31 instead of a custom mapping, don't change this file. If you have
                              a lot of Arduino code with fixed pin numbers and you need to map these
                              pins to specific pins of the nRF5 MCU; you need to change this file.
                              
                              If you fill the "g_APinDescription" Array with numbers between 0..31,
                              the Arduino pins 0..31 are assigned to pins P0.00..P0.31 of the MCU.
                              
                              As an example, if you need to change the pin mapping for Arduino pin 5
                              to P0.12 of the MCU, you have to write the 12 after PORT0 into the sixth
                              position in the  "g_APinDescription" Array.
                               
                              The extended attributes only affects the nRF5 variants provided with
                              official Arduino boards. The arduino-nrf5 variant ignores the extended
                              attributes.
                                
                              The pin mapping effects commands like "pinMode()", "digitalWrite()",
                              "analogRead()" and "analogWrite()".
                              
                              If you change the pin mapping, you have to modify the pins in
                              "MyBoardNRF5.h". Especially the analog pin mapping must be replaced with
                              your pin numbers by replacing PIN_AIN0..7 with a number of your mapping
                              array. You can use the constants PIN_AIN0..7 in the "g_APinDescription"
                              Array if you want to reference analog ports MCU independent. You cannot
                              use the pins P0.00 and P0.01 for GPIO, when the 32kHz crystal is connected.

                            @nca78 I tried to follow your instructions in post #1514 but I must be doing something wrong when I add files from the NRF5 SDK to my sketch folder because I keep getting some errors about missing files, so I keep adding and now I got to this point:

                              @korttoma sorry it seems I messed up with the files, this one is not from sdk.
                              Please take the one here, I'll clean up and reorganize later:

                                @nca78 still not getting anywhere with this. Would you mind ziping your sketch folder, then I should have all the correct files (right?). If I still have issues to compile I must be missing some library or are using the wrong version of something.

                                  Sure, but unfortunately I cannot upload a zip file here, please send me your email by private message.

                                    @alowhum there is a whole "movement" of people who are trying to reprogram them. Key issue is openability (how hard is to open it)
                                    The last easily openable watches are based on nrf51822, but the good thing is that programming pins are easily accesable and even marked SWD/SCLCK.
                                    Search Ali for ID107HR and google for "roger clark smartwatch"
                                    I am yet to find a watch that would be both nrf52 based AND easily openable

                                    or, perhaps a little easier, this one?

                                    I'm guessing that a typical jeweler would have the right tools to open it. Maybe get a little help with that part of it? I doubt it would cost much.

                                    Fortunately, there seem to be a plethora of different inexpensive nRF52832 watches available. Gobs of them.

                                      @neverdie AFAIK, they are all heavily glued to meet IPX67

                                        Just curious design consideration, based on my question to Nordic:

                                        https://devzone.nordicsemi.com/f/nordic-q-a/33448/led-power

                                        LED consumption will not exceed 0.5ma if the pin is configured as s0s1

                                          @toyman Maybe that's enough to light a subset of the pixels on the display?

                                          In theory these nRF52832 BLE are OTA re-programmable. If someone left the door open for that, then you wouldn't have to crack the case or fight with the glue. Well, maybe someday...
