The 1-Wire LCD controller connects to a Dallas 1-Wire network and functions as a slave device. This controller could be used to display information on a LCD under control of a 1-Wire network master. The 1-Wire LCD controller supports different standard text liquid crystal character displays (e.g. 2 Lines x 16 Characters LCD).

The 1-Wire LCD controller has the following built-in functionality:
  • Unique serial number.
  • Support for a wide range of LCDs, from 1 Line x 8 Characters up to 4 Line x 20 Characters.
  • Built-in LCD initialize: to ensure that the LCD is ready to display text after power-up.
  • Easy text displaying via scratchpad.
  • Direct LCD register and data memory access to enable full control of the LCD.
  • LCD power ON/OFF control.
  • LCD back-light ON/OFF control.
  • 3 Open collector general-purpose input/output pins (GPIO) and 1 general-purpose input only pin (GPI).
  • All inputs are sampled at 25mS intervals, any detected change will increment the input's event counter (counts up and down going events).
  • Open collector outputs can sink 10mA of current (direct LED drive with internal 470-Ohm resistor).
  • 112 bytes of EEPROM (Non-volatile storage).
OBS Ingen LCD-display ingår!
Enheten kräver matning +5V DC via 1wire-kabeln. Spänningen från DS9490R räcker till att driva 1st kontroller + display.

LCD-kontrollern ansluts till 1wire-nätet via en vanlig förlängningskabel som köps till separat.

Enheten stöds av OWFS. http://owfs.sourceforge.net/. (För att controllern skall hittas av owfs måste owfs startas med --usb_regulartime som argument).
