Please not that we're talking about ''display power supply'', not the backlight! 414 414 415 415 If you want to try so, you have to specify this signal with the ''Wire.Power'' entry in the config file (the default is ''GND'', i.e. no power from parport). To allow the display to settle down, there's a delay between rising this power-supply signal and the HD44780 initialisation sequence. You can modify this default delay of 500 msec with the ''Timing.POWER'' entry in the config file.
