# Protocols
|
||
|
|
|
||
|
|
Some subsystems (and in the case of KEY and EMIT, the core) re-
|
||
|
|
quire drivers to implement certain words in a certain way. For
|
||
|
|
example, the core requires drivers to implement (key) and (emit)
|
||
|
|
or else it won't know how to provide a console.
|
||
|
|
|
||
|
|
These protocols are described here.
|
||
|
|
|
||
|
|
# TTY protocol
|
||
|
|
|
||
|
|
(key) -- c Returns the next typed key on the console.
|
||
|
|
If none, block until there is one.
|
||
|
|
(emit) c -- Spit a character on the console.
|
||
|
|
|
||
|
|
# PS/2 protocol
|
||
|
|
|
||
|
|
(ps2kc) -- kc Returns the next typed PS/2 keycode from the
|
||
|
|
console. Blocking.
|
||
|
|
|
||
|
|
# SPI Relay protocol
|
||
|
|
|
||
|
|
(spie) -- Enable SPI device
|
||
|
|
(spid) -- Disable SPI device
|
||
|
|
(spix) n -- n Perform SPI exchange (push a number, get a
|
||
|
|
number back)
|
