// Description: MZ2500/2800 Key Matrix logic.
// This source file contains the logic to transmit the virtual key matrix, which is
// built from PS/2 scan codes, to the MZ2500/2800.
// This source file contains the application logic to obtain PS/2 scan codes, map them
// into a virtual keyboard matrix as per the Sharp MZ series key matrix and the
// logic to transmit the virtual key matrix to the MZ2500/2800.
//
// The application uses a modified version of the PS2KeyAdvanced
// https://github.com/techpaul/PS2KeyAdvanced class from Paul Carpenter.
//
// The application uses, for debug purposes, the esp-idf-ssd1306 class from nopnop2002
// https://github.com/nopnop2002/esp-idf-ssd1306.
//
// The application uses the Espressif Development environment with Arduino components.
// This is necessary for the PS2KeyAdvanced class, which I may in future convert to
// use esp-idf library calls rather than Arduino.
//
// The Espressif environment is necessary in order to have more control over the build.
// It is important, for timing, that the Core 1 is dedicated to MZ Interface
// logic and Core 0 is used for all RTOS/Interrupts tasks.
//
// The application is configured via the Kconfig system. Use idf.py menuconfig to
// configure.
