I/O Ports

In addition to the display control, the 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 128 keys
• Controlling of up to 16 outputs/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
• Touch screen control
• up to 512 Byte EEPROM emulation for user data
• MicroSD card control
• Real-time clock with battery backup

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