Description
WEO128128D-CTP est un écran OLED rond de Ø1,18 pouce, très populaire, doté d'un écran tactile capacitif intégré au module, d'une résolution de 128x128 points. Le module est équipé du circuit intégré SSD1327, prenant en charge une interface SPI à 4 lignes et I2C, avec une tension d'alimentation logique typique de 3V et un cycle de pilotage de 1/128. De plus, le modèle WEO128128D-CTP comprend le circuit intégré FT3268 pour panneau tactile intégré au module, prenant en charge l'interface I2C et disposant d'un seul point de détection pour l'écran tactile capacitif.
Ce modèle OLED rond WEO128128D avec CTP est idéal pour les applications de maison intelligente, les appareils technologiques intelligents, les systèmes énergétiques, les systèmes de communication, les instruments médicaux, etc. Ce module OLED offre un rapport de contraste élevé de 10 000:1 et un large angle de vision allant jusqu'à 160°, ce qui se traduit par des images plus claires. Le module peut fonctionner à des températures comprises entre -20℃ et +70℃, avec des températures de stockage allant de -30℃ à +70℃.

---|---|---|---|---|---|---|---|---|
1 | VSS | Ground pin. It must be connected to external ground. | ||||||
2 | 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. | ||||||
3 | 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. |
||||||
4 | 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. |
||||||
5 | VDD | Power supply pin for core logic operation. VDD can be supplied externally (within the range of 2.4V to 2.6V) or regulated Internally from VCI. A capacitor should be connected between VDD and VSS under all circumstances. |
||||||
6 | BS1 | MCU bus interface selection pins. Select appropriate logic setting as described in the following table. BS1 is pin select. Bus Interface selection
|
||||||
7 | IREF | This pin is the segment output current reference pin | ||||||
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 | 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. |
||||||
11 | D0 | 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. |
