    @rmtucker can't you just bit bang the I2C sensors? Should not be any mcu incapable of that. There should be plenty drivers available that implement a bit banged I2C driver.

    @Anticimex
    I managed to get a nokia 5110 display connected and working using the u8glib and softspi.
    I can not get the easier to use adafruit library to compile though.
    Nor have i been able to find a Soft i2c library that will compile without errors.
    So i am afraid i2c is still a non starter.

      maybe try this one https://github.com/felias-fogg/SlowSoftWire
      I don't use it, but it compiles fine for nrf52. I already tested it a while ago, and it worked for me.

        my head is battered with this.
        tried the library you mentioned and it compiled fine but still gave spurious readings.
        so i plugged the htu21d back in to a nano and used the sparkfun library demo.
        the readings were perfect.
        so frustrated with this because all my nodes use i2c sensors.

          Stupid question, but are your i2c sensors getting all the voltage that they need? After all, a nano runs at 5v, right? I know that some of the TH i2c sensors include voltage regulators, which would drop the voltage even further. If necessary, those could be removed. That's what I generally do.

            Yes They are 3.3v sensors.
            What we need is someone else using nrf51822 and i2c sensors that can shine some light.

              I'll try soon, hopefully I'll have time tomorrow, my nrf51 module is soldered on a breadboard. I need to make the promised tests on the nrf52 too ...

                Just an observation after many hours of tinkering.
                There is no problem reading one byte back from i2c,like when doing an i2c scan.
                It comes back with the address of the htu21d no problem.
                But if you try to read 3 bytes which is what you do when reading the temp etc,it goes T*TS up.

                  Well guys after all that :frowning:
                  I had not installed the development version from git.:angry:
                  After installling the development version the i2c is working fine.
                  Suprised no one else has done this??

                  From git (for core development)
                  
                  Follow steps from Board Manager section above
                  cd <SKETCHBOOK>, where <SKETCHBOOK> is your Arduino Sketch folder:
                  OS X: ~/Documents/Arduino
                  Linux: ~/Arduino
                  Windows: ~/Documents/Arduino
                  Create a folder named hardware, if it does not exist, and change directories to it
                  Clone this repo: git clone https://github.com/sandeepmistry/arduino-nRF5.git sandeepmistry/nRF5

                    Please can someone update the instructions below to mention installing the development version

                    Preparing Arduino
                    Arduino doesn't support the nRF5 platform in a standard setup. You have to add the arduino-nRF5 platform via Arduino's Board Manager like described in https://github.com/sandeepmistry/arduino-nRF5/#installing

                        If there are multiple libraries with the same name (as there seem to be), then how does the compiler know which one to pick? Is it just the first one whose name matches in whatever pathway it follows? Since it obviously compiled even though rmtucker was missing the proper libraries... this just sounds like a heartache waiting to happen unless everything is setup just-so. rmtucker's case seems to prove there won't be any warnings if it picks the wrong one.

                          looking at d00616 howto it's explained to use Mysensors development branch (or maybe he added it today :) ). but that makes sense as this port is newer than master branch.

                          @NeverDie
                          it uses the core libraries depending on the board used in Arduino.

                            @scalz: I think @rmtucker was discussing using the development version of the sandeepmistry nrf5 Arduino library, it was not related to the MySensors library.

                              Sorry i should have made it more understandable.
                              When you follow the instructions below as per sandeeps site it does not install the latest NR5 libraries that you see on github.

                              Installing
                              
                              Board Manager
                              
                              Download and install the Arduino IDE (At least v1.6.12)
                              Start the Arduino IDE
                              Go into Preferences
                              Add https://sandeepmistry.github.io/arduino-nRF5/package_nRF5_boards_index.json as an "Additional Board Manager URL"
                              Open the Boards Manager from the Tools -> Board menu and install "Nordic Semiconductor nRF5 Boards"
                              Select your nRF5 board from the Tools -> Board menu
                              

                              Following this you must install the development version aswell which is what you see on github by doing this.

                              From git (for core development)
                              
                              Follow steps from Board Manager section above
                              cd <SKETCHBOOK>, where <SKETCHBOOK> is your Arduino Sketch folder:
                              OS X: ~/Documents/Arduino
                              Linux: ~/Arduino
                              Windows: ~/Documents/Arduino
                              Create a folder named hardware, if it does not exist, and change directories to it
                              Clone this repo: git clone https://github.com/sandeepmistry/arduino-nRF5.git sandeepmistry/nRF5
                              Restart the Arduino IDE
                              

                              Otherwise you run into all kinds of problems using the old library.

                                I have added a note at the end of the installation documentation. To make things easier, I have opened an issue to update the Arduino-nRF5 release.

                                  I2C should be fixed now. Version 0.4.0 is released!

                                      If this don't work, remove all folder created by hardware and boards manager, close Arduino IDE and reinstall it via Boards Manager.

                                          To help clarify for others who are reading this: the Arduino IDE board manager let me upgrade to 0.4.0 from 0.3.0 by just clicking on the board entry "Nordic Semiconductor NRF5 Boards by Sandeep Mistry", selecting the 0.4.0 version, and then clicking Install.
