Descrizione

WEO012864G è il display OLED grafico da 2,42 pollici più popolare con pannello tattile capacitivo sul modulo; che ha una risoluzione di 128x64 punti. Questo modulo è dotato di IC SSD1309, supporta l'interfaccia parallela 6800/8080 a 8 bit, I2C e 4-Wire SPI, tensione di alimentazione per la logica 3V, tensione di alimentazione per il display 13V, ciclo di lavoro 1/64. Questo modello WEO012864G è anche dotato di IC touch panel GT911 sul modulo, che supporta l'interfaccia I2C, un punto di rilevamento per CTP. Questo modulo OLED presenta un rapporto di contrasto elevato di 10.000:1, con conseguente immagini più nitide sul display.

Questo modello WEO012864G da 2,42" con CTP è ideale per applicazioni di domotica, dispositivi tecnologici intelligenti, sistemi energetici, dispositivi di misurazione, sistemi di comunicazione, strumenti medici, ecc. Questo modulo può funzionare a temperature comprese tra -20℃ e 70℃; la sua temperatura di conservazione varia da -30℃ a 80℃.

Power supply pin for core logic operation

BS1

MCU bus interface selection pins. Select appropriate logic setting as described in the following table. BS2, BS1 and BS0 are pin select

	BS1	BS2
I2C	1	0
4-wire Serial	0	0
8-bit 68XX Parallel	0	1
8-bit 80XX Parallel	1	1

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

BS2

No connection

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.

D/C#

This pin is Data/Command control pin connecting to the MCU.
When the pin is pulled HIGH, the data at D[7:0] will be interpreted as data.
When the pin is pulled LOW, the data at D[7:0] will be transferred to a command register.
In I2C mode, this pin acts as SA0 for slave address selection.

R/W#

This pin is read / write control input pin connecting to the MCU interface.
When 6800 interface mode is selected, this pin will be used as Read/Write (R/W#) selection input. Read mode will be carried out when this pin is pulled HIGH and write mode when LOW.
When 8080 interface mode is selected, this pin will be the Write (WR#) input. Data write operation is initiated when this pin is pulled LOW and the chip is selected.
When serial or I2C interface is selected, this pin must be connected to VSS.

E/RD#

This pin is MCU interface input.
When 6800 interface mode is selected, this pin will be used as the Enable (E) signal.
Read/write operation is initiated when this pin is pulled HIGH and the chip is selected.
When 8080 interface mode is selected, this pin receives the Read (RD#) signal. Read operation is initiated when this pin is pulled LOW and the chip is selected.
When serial or I2C interface is selected, this pin must be connected to VSS.

20~27

D0~D7

These pins are bi-directional data bus connecting to the MCU data bus.
Unused pins are recommended to tie LOW.
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.

IREF

This pin is the segment output current reference pin.
IREF is supplied externally.

VCOMH

COM signal deselected voltage level.
A capacitor should be connected between this pin and VSS.

VCC

Power supply for panel driving voltage. This is also the most positive power voltage supply pin.

NC(GND)

No connection
