Re: Game controller
that being said, it's possible to write code to handle combinations of those keypresses (e.g., "all mashed down at once") separately from the individual strokes. you either need to intercept the keys at a pretty low level (scan codes) and keep track of the up and down state of every key, or you can read the keys normally and use a user-level timer to decide whether more than one has been pressed in very quick succession. paul i wrote: > the "game controller" is simply 4 separate electrical contacts with a > button large enough to push them individually or together (in some > combinations). the resulting presses are reported as keyboard > keystrokes. if i remember correctly, these buttons are bound to the > "keypad" versions of the arrow keys, i.e. KP_UP, KP_RIGHT, etc. use > 'xev' to check me on this. > > paul > > peter wrote: > > Hi, > > > > I'm interested in use of the game controller or controllers in > > place of the TouchPad or mouse.

Re: Game controller
the "game controller" is simply 4 separate electrical contacts with a button large enough to push them individually or together (in some combinations). the resulting presses are reported as keyboard keystrokes. if i remember correctly, these buttons are bound to the "keypad" versions of the arrow keys, i.e. KP_UP, KP_RIGHT, etc. use 'xev' to check me on this. paul peter wrote: > Hi, > > I'm interested in use of the game controller or controllers in > place of the TouchPad or mouse.

Game controller
Hi, I'm interested in use of the game controller or controllers in place of the TouchPad or mouse. This is relevant to eBook mode where the TouchPad is not accessible and a mouse is not convenient. This is what I have. [olpc@xo-53-1d-bb ~]$ cat /boot/olpc_build 13.2.5 for XO-1.5 (build 17) bash-4.2# evtest No device specified, trying to scan all of /dev/input/event* Available devices: /dev/input/event0: Lid Switch /dev/input/event1: Power Button /dev/input/event2: AT Translated Set 2 keyboard /dev/input/event3: EBook Switch /dev/input/event4: olpc-kbdshim virtual keyboard /dev/input/event5: SynRelPS/2 Synaptics TouchPad /dev/input/event6: olpc-kbdshim virtual mouse /dev/input/event7: USB Optical Mouse Select the device event number [0-7]: No mention of the Game controller. Is any joystick device present? [olpc@xo-53-1d-bb ~]$ ls -l /dev/j* ls: cannot access /dev/j*: No such file or directory Can any Linux software detect or communicate with this game controller?
