Description
WEO012864Q-CTP est un écran OLED graphique COG de 2,7 pouces avec panneau tactile capacitif sur module, d'une résolution de 128x64 points. Ce module est équipé du circuit intégré SSD1309 et prend en charge une interface parallèle 6800/8080 8 bits, une interface SPI à 4 fils et I2C. La tension d'alimentation pour la logique est de 2,8V à 3,3V, avec une valeur typique de 3,0V, la tension d'alimentation pour l'affichage est de 13V, avec un cycle d'entraînement de 1/64. Ce modèle WEO012864Q-CTP intègre le circuit GT911 pour le panneau tactile, prenant en charge l'interface I2C et un point de détection pour l'écran tactile capacitif.
Ce modèle WEO012864Q de 2,7 pouces avec CTP est idéal pour les applications de maison intelligente, les appareils de technologie intelligente, les systèmes énergétiques, les appareils de mesure, les systèmes de communication, les instruments médicaux, etc. Ce module peut fonctionner à des températures allant de -20°C à 70°C ; ses températures de stockage s'étendent de -30°C à 80°C. Avec un rapport de contraste élevé de 10 000:1 et un angle de vision étendu jusqu'à 160°, ce module OLED garantit des images d'affichage plus claires.

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 |
