View source for Programmers Notes for PadOrbiter

Contained on this page are my notes for the PadOrbiter. Particularly in regards to the various bits of glue software that make the user experience more convenient.

== TabletCFG ==

[[TabletCFG]] is the Configuration program for setting network parameters on the [[PadOrbiter]]. It modifies various configuration files to configure network parameters for the [[PadOrbiter]] to function properly. 

=== Network Configuration Snippets ===

TabletCfg needs to modify various files to configure network parameters for the wireless card. These files are overwritten completely each time the configuration changes.

==== WPA-PSK ====

WPA-PSK requires that a configuration file for /etc/wpa_supplicant.conf and /etc/network/interfaces be modified. 

===== /etc/wpa_supplicant.conf =====

 ctrl_interface=/var/run/wpa_supplicant
 #ap_scan=2
 
 network={
        ssid="your_ssid"
        scan_ssid=1
        proto=WPA RSN
        key_mgmt=WPA-PSK
        pairwise=CCMP TKIP
        group=CCMP TKIP
        psk=your_psk
 }

'''Note:''' Add needed changes for using AES256 WPA encryption.

===== /etc/network/interfaces =====

 auto eth0
 iface eth0 inet dhcp
 pre-up wpa_supplicant -Bw -Dwext -ieth0 -c/etc/wpa_supplicant.conf
 post-down killall -q wpa_supplicant

=== On-Screen Keyboard Notes ===

Due to the tablet nature of the PadOrbiter, an on-screen keyboard was necessary. It is embedded directly into the configuration window itself. I had tried various external keyboards, but was unsuccessful in finding a keyboard that was easy to use for this purpose. 

The Keyboard merely appends the given letter to the cursor position (or removes it in the case of backspace) of the text field. 

'''TODO:''' Find which ESSIDs are legal. Do I need to create an extended keyboard to support funky characters?

== Todo ==

* Finish TabletCFG '''(CRITICAL)'''
* Replace bootscreen with LinuxMCE splash. '''(NICE TO HAVE)'''
* Modify Orbiter to allow for automatic configuration without needing to create an orbiter in the web admin. '''(CRITICAL)'''
* Optimize Boot process. '''(NICE TO HAVE)'''
