"Hijack" Menu System, with VolAdj, IR-Translate, and much more!

If you find yourself continually having to adjust the player volume up/down for each song, then this hack is exactly what you need to cure the problem. The original VolAdj code was by Richard Lovejoy.

This enhanced version includes a new front panel menu system for controlling the automatic volume adjustment and tons of other stuff. There are separate VolAdj settings for home/car use, preserved over (most) power cycles (initially "Off" after installation). VolAdj options include "Off", "Low", "Medium", and "High", using values suggested by tfabris ("FAQ-Master").

To access the Hijack menu system, press and hold-in either the rotary KNOB, or the (Rio remote) MENU button, until the menu appears. Alternatively, press/release the (Kenwood remote) CD button three times in succession to activate the menu. Once in the menu system, navigate using either the KNOB, or the NEXT/PREV track buttons on the remote. To activate a menu selection, press the KNOB (or CD or MENU button on the remote). To exit from the menu, either wait 5 seconds, or press the front-panel TOP button or (Kenwood remote) '*' or (Rio remote) CANCEL button

Most menu functions utilize the same buttons (KNOB, NEXT/PREV track to move around, CD or MENU to select, TOP or '*' or CANCEL to quit). The menu system has grown considerably since its introduction, and now sports numerous features (click for a list).

Click here for instructions on configuring IR-Translations (for third-party remote controls, or even the stock ones). Certain other settings can also be modified in config.ini, using the syntax shown below:

	voladjlow=0x1800,100,0x1000,25,60     ;default value shown
	voladjmed=0x2000,409,0x1000,27,70     ;default value shown
	voladjhigh=0x2000,3000,0xc00,30,80    ;default value_shown
	temperature_correction=-4             ;default value shown (degrees C)
	button_pacing=20                      ;default value shown (1/100ths of a second)
	old_style=1                           ;use "original style" of hijack menus
	supress_notify=1                      ;for use with [output]notify=1
Click here for more information on using custom VolAdj settings in the config.ini file.

Hijack has built-in FTP and HTTP servers for remote access, and remote playlist browsing capability for use in conjunction with web browsers and audio playback software. To access this feature, just point a web browser at http://your.players.ipaddr/ and click on the link at the bottom of the page.

There is also an evolving ioctl() interface for binding userland extensions into the menu system. If you want to add your own userland application to the menus, check out the comments at the top of hijack.h for details.
There is now an excellent Hijack FAQ hosted at RioCar.Org

Installing the Kernel (easier than you'd expect)

To use this version of the "Hijack" menu system, your car player must already be running v2 or v3 player software from Empeg/Rio. Then, grab the POSIX (Linux and friends) Empeg download.c utility (recently updated to work with USB-Serial adapters!), and compile and run it under Linux as follows:
     cc -O -o download download.c
     ## Power OFF your player, and connect up the factory serial cable
     ./download  ZZZZZZZZZZ.zImage  10000
     ## The program will now prompt you to power up the player
Of course, you'll have to replace the 'ZZZZZZZZZ' with the correct kernel filename (see below),
MS-Windows users should use Tony's Empeg Logo Editor to install the hacked kernel, rather than the download procedure above. Even if you've never installed a custom kernel before, try it, it's much easier than you might expect.

Is This Safe?

I've been hacking Linux as a member of the core Linux kernel development team since 1992, best known as the original "Linux IDE Guy", writing/maintaining the drivers for ATA/IDE disks, tapes, cdroms, etc.. I wrote my first Pong implementation on an Apple-II computer in 1981. So, I guess I do have a little experience with this stuff.

But even if it does mess things up, just reinstall the original official software (a .upgrade file) again, and it will restore your player back to it's pre-experiment condition. -- Mark Lord
