typedef Mpr121I2C

using daisy::Mpr121I2C = typedef Mpr121<Mpr121I2CTransport>;

---

enum Tca9534Mode

enum Tca9534Mode {
    INPUT,
    OUTPUT
};

Pin direction for a single TCA9534 pin.

---

enum Tca9534Register

enum Tca9534Register {
    INPUT = 0x00,
    OUTPUT = 0x01,
    POLARITY = 0x02,
    CONFIG = 0x03
};

Registers for the TCA9534 8-bit I2C GPIO expander. See TI datasheet SCPS208 (TCA9534).

Note: unlike the MCP23017, the TCA9534 has no internal pull-ups. Use external resistors on input pins.
