DESCRIPTION

The round OLED model is an extension item which equipped with capacitive touch screen and a control knob on module, it’s an Ø1.18” circular COG type OLED display; made of resolution 128x128 dots. This module is built in with SSD1327 IC, it supports 4-line SPI and I2C interface, supply voltage for logic 3V (typical value), 1/128 driving duty. This CTP+Knob model is built in with IT7259 touch panel IC on module, which supports I2C interface, one detect point for capacitive touch screen.

This round OLED Knob is ideal for applications which required a control knob on devices such as smart home applications, intelligent technology devices, audio system, etc. Operating temperatures from -20℃ to +50℃; storage temperatures range from -30℃ to +70℃.

Interface Pin Function

No.

Symbol

Function

VSS

Ground pin. It must be connected to external ground.

VCC

Power supply for panel driving voltage. This is also the most positive power voltage supply pin. It is supplied by external high voltage source.

VCOMH

COM signal deselected voltage level. A capacitor should be connected between this pin and VSS. No external power supply is allowed to connect to this pin.

VCI

Low voltage power supply and power supply for interface logic level. It should match with the MCU interface voltage level and must be connected to external source. VCI must always set to be equivalent to or higher than VDD.

VDD

Power supply pin for core logic operation.

BS1

MCU bus interface selection pins. Select appropriate logic setting as described in the following table. BS1 is pin select. Bus Interface selection

BS1	Interface
0	4-line SPI
1	I2C

Note (1) 0 is connected to VSS (2) 1 is connected to VCI

IREF

This pin is the segment output current reference pin

CS#

This pin is the chip select input connecting to the MCU. The chip is enabled for MCU communication only when CS# is pulled LOW (active LOW).

RES#

This pin is reset signal input. When the pin is pulled LOW, initialization of the chip is executed. Keep this pin pull HIGH during normal operation.

DC#

This pin is Data/Command control pin connecting to the MCU. When the pin is pulled HIGH, will be interpreted as data. When the pin is pulled LOW, will be transferred to a command register In I2C mode, this pin acts as SA0 for slave address selection.

When serial interface mode is selected, D0 will be the serial clock input: SCLK; D1 will be the serial data input: SDIN and D2 should be kept NC. When I2C mode is selected, D2, D1 should be tied together and serve as SDAout , SDAin in application and D0 is the serial clock input, SCL.
