747IPC Interface

Broker keys used in communicating with 747IPC.

Broker Keys
-----------

Input keys:



IPC.scratchpad [string | {string with spaces}]
inserts the string into the FMC scratchpad.

    the FMC keyboard *doesn't* need to be switched on.

    maximum length is 23 characters.


IPC.fmckeyb [0/1]
switches on/off the FMC keyboard


IPC.keypress {1 xxxx}
where xxxx = keycode. See keycodes.txt.


IPC.pushsw {xx yy}
where xx = keycode, yy = action. See pushsw.h.


IPC.poke {xx dd dd}
where xxxx is the offset in PS1's data segment of the variable to be poked, in hexadecimal only;

yy is the data to be poked, in decimal;

zz is the size of the data in bytes, decimal.


IPC.pokeSust {xx dd dd}
arguments as above, however 747IPC's behaviour is different. The data will be repeatedly poked at up to 20 Hz, until a cancellation order is received. This takes the form
   "IPC.pokeSust {xxxx 0 0}"
where xxxx must be the same value as the previous start order.

Note that you can have up to 8 addresses in the IPC.pokeSust list at any time. You must individually cancel each address that was previously added to the list, as detailed above.


IPC.pokeN1 {aa bb cc dd}
where the 4 arguments are in decimal and represent the "target N1 equivalent"
in percentage units x 10.

eg on the GE-engine configs,

   "IPC.pokeN1 {500 500 500 500}"
will set 50.0% N1 on all 4 engines.

On non-GE types, the actual N1 may not be 50.0% but it should be true that
any given value will always correspond to the same thrust lever position in PS1.
