Technical Notes & Reference Details

  • to make hardware prototypes faster, simpler and easier. Our goal is to build an ecosystem of hardware that utilizes the Open Architecture as a launching point for your next project.
  • Getting started with the Github Code:
  • 1- Download the Repo
  • 1.1 Navigate to:
  • https://github.com/pureengineering/puremodules
  • -Select the "Clone or Download" button as shown below.
  • -Download Zip File.
  • -Open you Downloads folder and Unzip the file.
  • Take note of the Directory you unzip this folder to. I will refer to this directory as [YOURDIRECTORY].
  • 2- Setup your environment
  • The CoreModule uses an Nrf52. This section will guide you in setting up the environment for the Nrf52.
  • 2.1- Open a Command Prompt.
  • -On windows you can type "cmd" in the search bar.
  • -On Linux Press CTRL+ALT+T
  • 2.2- Start by running the Makefile to setup the NRF52 SDK:
  • -First navigate to the correct folder by typing this command in the command prompt:
  • > cd
  • [YOURDIRECTORY]
  • \PUREmodules-master\PUREmodules-master\Nrf52
  • -Once in this directory, make the file using the make command below to download the Nordic SDK.
  • >make
  • Note: This may take some time to install.
  • THE STEP ABOVE SHOULD THROW THIS ERROR:
  • >"make: *** [nRF5_SDK_12.2.0_f012efa/external/micro-ecc/micro-ecc] Error 2"
  • This is fine and will corrected in the next step.
  • Windows:
  • If the command "make" gives a different error, click
  • here
  • for a guide on how to setup the necessary tools.
  • Linux:
  • -Other Possible errors when running "make" include:
  • "make curl: Command not found". If you receive this error click
  • here
  • and complete Step 2.
  • "make: Command not found". If you receive this error click
  • here
  • and complete Step 1.
  • If you have any of the two errors above, redo Step 2.2 after they have been corrected.
  • Once complete your Nrf52 directory should have the SDK. Highlighted below are the directories that have been added by this step.
  • 3- Correct GCC Version
  • We need to match the Gcc version on your computer to the one specified by the code.
  • Open the file:
  • [YOURDIRECTORY]\nRF5_SDK_12.2.0_f012efa\components\toolchain\gcc\Makefile.windows
  • You can see your GCC version by opening your computer's Environmental Variables under the PATH variable.
  • Linux:
  • To see your version number run
  • $ cat proc/version
  • 4- Correct Missing micro-ecc library error
  • As mentioned in step 2.2 running "make" in the Nrf52 directory should throw an error because this external library has not been compiled. To compile it follow these steps.
  • 4.1- Start by navigating to the library's directory using the following command in your terminal window
  • >cd [YOURDIRECTORY]\nRF5_SDK_12.2.0_f012efa\external\micro-ecc\nrf52_armgcc\armgcc
  • > make
  • This will compile the micro-ecc library.
  • You are now ready to flash some code into the Nrf52.
