// It will determine how a laptop keyboard matrix is wired using a Teensy 3.2 on an FPC daughterboard.
|
||||||
|
// Open an editor on a computer and load or create a file that lists every key
|
||||||
|
// on the laptop keyboard that will be tested. Connect the FPC cable of the test keyboard
|
||||||
|
// to the Teensy/FPC board. Connect a USB cable from the Teensy to the computer.
|
||||||
|
// Wait a few seconds for the computer to see the Teensy as a keyboard. If numbers are reported on the screen
|
||||||
|
// before any keys are pressed, these pin numbers are shorted together and must be fixed.
|
||||||
|
// Press each key one by one on the test keyboard as listed on the editor screen. When a key
|
||||||
|
// is pressed on the test keyboard, the program detects which two pins on the FPC connector
|
||||||
|
// were connected. Those two pin numbers are sent over USB (separated by a TAB) and displayed
|
||||||
|
// on the editor. After sending the numbers, a DOWN ARROW is sent over USB to prepare for
|
||||||
|
// the next key. Once all keys on the test keyboard have been pressed, the file in
|
||||||
|
// the editor can be saved to create a row-column matrix.
|
||||||
|
//
|
||||||
|
// If your keyboard has diodes, you must pay attention to the order of the two pins that are reported by the Teensy. The code performs
|
||||||
|
// a bottom up test first, followed by a top down test so that one of the two tests will forward bias the diode.
|
||||||
|
// The first pin reported over USB is the cathode side and the second pin is the anode side. The diode direction must be taken into
|
||||||
|
// account when programming the TMK or Teensyduino keyboard routine.
