Quick TODO --------------------------------------------------------------------

- write language unit test
- more maple-specific example programs
- maple mini serial bootloader HOWTO
- maple and mini jtag HOWTO

Peripherals -------------------------------------------------------------------

- I2C wrap up
- SPI wrap up

Arduino Library functions to port (these are LGPL) ----------------------------

EEPROM:
    functions:
        uint8 read(int)
        void write(int, uint8)

Firmata:
    edit Firmata.h for capabilities

Matrix:
    soft spi port stuff

SoftwareSerial:
    clockCyclesToMicroseconds(int)

Sprite:
    all good?

LiquidCrystal:
    timing on soft serial send() commands

Stepper:
    requires millis()

Wire:
    reimplementation of the utility/twi.{c/h} code:
        void twi_init(void);
        void twi_setAddress(uint8_t);
        uint8_t twi_readFrom(uint8_t, uint8_t*, uint8_t);
        uint8_t twi_writeTo(uint8_t, uint8_t*, uint8_t, uint8_t);
        uint8_t twi_transmit(uint8_t*, uint8_t);
        void twi_attachSlaveRxEvent( void (*)(uint8_t*, int) );
        void twi_attachSlaveTxEvent( void (*)(void) );
        void twi_reply(uint8_t);
        void twi_stop(void);
        void twi_releaseBus(void);

Ethernet:
    ho baby...
    uses avr/interrupt.h
    reimplement utility/spi stuff
