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 ...

@Nca78
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.

rmtucker

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
Restart the Arduino IDE```

@rmtucker

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

@d00616 maybe ? :)

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.

scalz

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.

rmtucker

@mfalkvidd
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.

https://github.com/sandeepmistry/arduino-nRF5/issues/182

d00616

I2C should be fixed now. Version 0.4.0 is released!

rmtucker

@d00616
So should i be able to delete the hardware folder that the development version created from github and just update from boards manager?.

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

Hi, I don't us nrf52 yet but as i'm a platformio supporter, There is a new release for nrf52 platform with initial arduino framework support ! Good news, i think I will test nrf52 in few weeks.
https://github.com/platformio/platform-nordicnrf52/releases/tag/v1.2.0

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.

I have updated the radio driver with fixes for some hardware errata.
I have updated the https://github.com/mysensors/ArduinoHwNRF5 with an enhanced definition format. File name and contents are changed! The board description is compatible with the NRF5 variant provided by Arduino, but it's not possible to use this variant at the moment.

Where do we find the update? i.e. is it baked into the regular MySensors development code thread, or is it elsewhere?

NeverDie

I'm guessing it's this one? https://github.com/mysensors/ArduinoHwNRF5

NeverDie

I refreshed all the libraries. I'm able to compile and upload my sketches, but now it complains a lot about "invalid libraries."
