  • Interfaces

    I2C  Inter-integrated circuit protocol uses clock and data lines to communicate short distances at slow speeds from a master to up to 128 addressable slave devices. A display is a slave device.

    RS232  Recommended standard 232, a common serial protocol. Logic levels can be as high as +/-30V, a high level is negative, a low is positive.

    RS422  Recommended standard 422, a more robust differential pair serial protocol.

    TTL  Transistor-transistor logic applied to serial protocol. Low level is 0V while high logic is 5V.

    USB  Universal Serial Bus protocol widely used in PCs.

  • Features

    Dallas One-Wire  One Wire interface for connecting devices using Dallas Semiconductor protocol, such as the DS18S20 temperature probe.

    GPO  General Purpose Outputs for switching external circuitry and devices.

    Keypad  Matrix style keypad input.

    Piezo  Piezo Electric buzzer with variable pitch and duration.
