Beschreibung
WEO012864Q-CTP ist ein beliebtes 2,7-Zoll-COG-Grafik-OLED-Display mit kapazitivem Touchscreen auf dem Modul; es hat eine Auflösung von 128x64 Punkten. Dieses Modul ist mit dem SSD1309-IC ausgestattet und unterstützt eine 6800/8080 8-Bit-Parallel-, 4-Draht-SPI- und I2C-Schnittstelle. Die Versorgungsspannung für die Logik beträgt 2,8V bis 3,3V, der typische Wert beträgt 3,0V, die Versorgungsspannung für das Display beträgt 13V, die Ansteuerpflicht beträgt 1/64. Das WEO012864Q-CTP-Modell verwendet das GT911 als Touch-IC, das die I2C-Schnittstelle und einen Detektionspunkt für CTP unterstützt.
Dieses 2,7-Zoll WEO012864Q mit CTP-Modell eignet sich ideal für Smart-Home-Anwendungen, intelligente Technologiegeräte, Energiesysteme, Messgeräte, Kommunikationssysteme, medizinische Instrumente usw. Dieses Modul kann bei Temperaturen von -20°C bis 70°C betrieben werden, die Lagertemperaturen liegen zwischen -30°C und 80°C. Mit einem hohen Kontrastverhältnis von 10.000:1 und einem erweiterten Betrachtungswinkel von bis zu 160° sorgt dieses OLED-Modul für klarere Anzeigebilder.

5 | VDD | Power supply pin for core logic operation | |||||||||||||||
6 | BS1 | MCU bus interface selection pins. Select appropriate logic setting as described in the following table. BS2 and BS1 are pin select
(1) 0 is connected to VSS (2) 1 is connected to VDD |
|||||||||||||||
7 | BS2 | ||||||||||||||||
8 | 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). |
|||||||||||||||
9 | 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. |
|||||||||||||||
10 | 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. |
|||||||||||||||
11 | 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. |
|||||||||||||||
12 | 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. |
|||||||||||||||
13-20 | 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. |
|||||||||||||||
21 | IREF | This pin is the segment output current reference pin. IREF is supplied externally. |
|||||||||||||||
22 | VCOMH | COM signal deselected voltage level. A capacitor should be connected between this pin and VSS. |
|||||||||||||||
23 | VCC | Power supply for panel driving voltage. This is also the most positive power voltage supply pin. | |||||||||||||||
24 | NC(GND) | No connection |
