I/O Ports

In addition to the display control, the DPC10XX iLCD Controllers carry out all necessary I/O based tasks, thus allowing for further simplification of your hardware design:

• Keyboard matrix scanning for up to 32 keys
• Controlling of up to 6 LEDs (on/off/blink with user selectable blink frequency)
• Up to 4 ADC inputs for analog measurements or up to 4 digital inputs
• Controlling of 2 relays
• Alternative to the relays: PWM outputs (e.g. for speaker or buzzer)
• Adjustable watchdog for controlling your hardware
• ATX power supply control
• Alternatively to ATX control: prepared for upcoming touch screen control
• 512 Byte EEPROM emulation for user data

The extremous fast 32-Bit DPC20xx and DPC30xx (color) iLCD controllers are not available separately currently. These controllers have additional features as follows:

• Keyboard matrix scanning for up to 128 keys
• Up to 16 digital outputs and 16 digital inputs
• Inputs, outputs and keyboard columns can be freely assigned
• Real-time clock with battery backup

Depending on the purpose, different iLCD Panels and Controller Boards with different I/O ports can be delivered. Please visit the appropriate pages for more information.
