Phil was kind enough to donate me one LCD with a "broken" firmware. This would stuck the SCL low for good on any read attempts. Otherwise working unit. For the keypad, you would just poll with a read byte (?) command, and it returns nonzero if something was pressed. I don't know if there is any queue, but how fast a typist are you, really? There is a patch for (old) LCDProc to do /dev/i2c-x, somewhere. -- Ky?sti M?lkki <kyosti.malkki at welho.com>
