Detailed Description

This driver supports the I2C-based LCD driver type NXP PCF85162. The LCD driver IC has 32 segment driver outputs and up to 4 backplanes, and can operate in static mode or multiplexing modes 1:2, 1:3 or 1:4. The LCD driver IC has also built-in versatile blinking modes. Wide IC power supply range from 1.8V to 5.5V, and wide logic LCD supply range from 2.5V to 6.5V.

The LCD driver IC has 1 address line. The I2C address range is 0x38 - 0x39. Max baudrate is 400 kbit/s. Typical current consumption is 6µA for the IC and 18µA for the LCD.

Both initialization, flashing control and printing at the LCD are supported.

The selected I2C port must be initialized before using the driver.
