//
|
|
||||||
// This software is in the public domain.
|
|
||||||
// It will determine how a laptop keyboard matrix is wired using a Teensy LC on an FPC T61 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 I/O 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 Teensy I/O's
|
|
||||||
// were connected. Those two I/O's 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.
