The MAX7360 is an I2C key-switch and led controller, with following functionalities: - Keypad controller for a key matrix of up to 8 rows and 8 columns. - Rotary encoder support, for a single rotary encoder. - Up to 8 PWM outputs. - Up to 8 GPIOs with support for interrupts and 6 GPOs. Chipset pins are shared between all functionalities, so all cannot be used at the same time.
