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