Bare Conductive

Bare Conductive MPR121 grapher

Processing sketch that graphs capacitive electrode data from the Bare Conductive Touch Board or Bare Conductive Pi Cap over time.

Requirements

Install

  1. Close the Processing IDE if you have it open.

  2. Download the .zip or clone the repository to your local machine - if downloading the .zip, extract the contents somewhere that suits you.

  3. Take the mpr121_grapher folder and move it to Processing Sketchbook Folder. This will be different for each operating system:

    Windows

    Libraries\Documents\Processing

    or

    My Documents\Processing

    Mac

    Documents/Processing

    Linux (Ubuntu)

    Home/Processing

    If this folder does not exist, create it first.

  4. Reopen the Processing IDE - you should now be able to open the sketch in the File -> Sketchbook menu.

Note

The new functions in this version of the Grapher use EEPROM to save and restore thresholds automatically when setting them. However, if you're using a SAMD21 or SAMD51 board (like the Arduino Zero or Adafruit Metro M4), these MCUs don't have onboard EEPROM. As a result, these functions will not work.

You can’t perform that action at this time.
