notes

• LCD pin 18 should be left unconnected.
• different backlight types:
  • only displays with EL-foils and inverters with input voltage 5V could be tested.
  • if a display with LED-backlight is connected follow the instructions and limits that are given in the data sheet (you might need to add a buffer resistor or you might even need an extra voltage source that is higher than 5V)

circuits:

simple wiring with hardware reset ('Simple')

• default wiring
• this wiring only requires two extra signal lines
• reset line is controlled using a hardware circuit
• backlight cannot be controlled by software

   part list:
   ----------

   Part#   Type                Value                  Annotation
   ---------------------------------------------------------------------------------------
   R1-R10  Resistor            1 kOhm
   R11     Var.Resistor        eg. 220 kOhm           some value around 220k worked best for me
   R12     Resistor            10 kOhm
   C1      Capacitor           10 uF
    

simple wiring with software reset ('SimpleSWRes')

• three signal lines required
• reset line controlled by software
• backlight cannot be controlled by software

   part list:
   ----------

   same as in wiring 'Simple' with the following changes:
      * R12 is 1 kOhm
      * C1 not required
    

standard wiring with hardware reset ('Standard')

• the same as in 'Simple' but with two additional signals:
  • R/W is wired to pin 14 / /AUTO via a buffer resistor (1 kOhm)
  • /CS is wired to pin 17 / /SELIN via a buffer resistor (1 kOhm)

standard wiring with software reset ('StandardSWRes')

• the same as in 'SimpleSWRes' but with one additional signal:
  • R/W is wired to pin 14 / /AUTO via a buffer resistor (1 kOhm)

simple wiring with hardware reset ('Simple')

• three signal lines required
• reset line is controlled using a hardware circuit
• backlight can be controlled by software

wiring with backlight and software reset ('BacklightSWRes')

• four signal lines required
• reset line controlled by software
• backlight can be controlled by software

   part list:
   ----------

   same as in wiring 'Backlight' with the following changes:
      * R12 is 1 kOhm
      * C1 not required
    

using the third parameter of serdisp_init(), driver specific options and custom wiring can be set.
common information about passing options and customisable wiring can be found in a separate document.

    examples:

      serdisp_init(sdcd, "DG16080", "INVERT=YES;ROTATE=90");
      serdisp_init(sdcd, "DG1608011", "ROTATE=YES");
    

  0 .. no delay
  1 .. one call of gettimeofday()
 >1 .. delay at least x nanoseconds
