|

|
|
* In order to get the Teensy to work, we need to move pin 1 to a different pin. This is
|
||
|
|
* because on the Teensy pin 1 is ground, but we need to write to pin 1 in order to read
|
||
|
|
* the keyboard matrix. An ideal pin to move it to is VPP (pin 31), because this pin tells
|
||
|
|
* the 8051 whether it should read from external or internal memory. The Teensy doesn't
|
||
|
|
* care about that.
|
||
|
|
*
|
||
|
|
* The easiest way to reassign the pin is to use standoffs. You can check out this thread:
|
||
|
|
* https://geekhack.org/index.php?topic=12212.msg235382#msg235382 for a picture of what
|
||
|
|
* this looks like. Note that in the picture the pin has been reassigned to pin 12. We
|
||
|
|
* don't want to do that because we're going to use that pin to send data over PS/2.
|
||
|
|
*
|
||
|
|
* We could if we wanted also reassign the PS/2 pins to Teensy hardware UART pins, but
|
||
|
|
* that's more work. Instead we'll just bit-bang PS/2 because it's an old, slow protocol
|
||
|
|
* (and because there's already a bit-banged PS/2 host implementation in QMK - we just
|
||
|
|
* need to add the device side).
|
||
|
|
*
|
||
|
|
* So overall, we want the following inputs and outputs:
|
||
|
|
* Outputs:
|
||
|
|
* Matrix:
|
||
|
|
* PB7
|
||
|
|
* PD0
|
||
|
|
* PD1
|
||
|
|
* PE6 (moved from pin1, GND)
|
||
|
|
* LEDs:
|
||
|
|
* PB3-6
|
||
|
|
* PF4-7
|
||
|
|
* Inputs:
|
||
|
|
* Matrix:
|
||
|
|
* PD2-5
|
||
|
|
* I/Os (start up as inputs):
|
||
|
|
* PS/2:
|
||
|
|
* PC1
|
||
|
|
* PE1
