SPECIFICHE TECNICHE
Funzione dei Pin di Interfaccia
| No. | Simbolo | Funzione | ||||||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| 1 | ESD_GND | ESD Ground pin | ||||||||||||
| 2 | VPP | OLED panel power supply. | ||||||||||||
| 3 | VSS | This is a ground pin. | ||||||||||||
| 4 | VSS | This is a ground pin. | ||||||||||||
| 5 | VDD | Power Supply for Logic | ||||||||||||
| 6 | __ CS |
This pad is the chip select input. When /CS = “L”, then the chip select becomes active, and data/command I/O is enabled. | ||||||||||||
| 7 | ___ RES |
This is a reset signal input pad. When /RES is set to “L”, the settings are initialized. The reset operation is performed by the /RES signal level. | ||||||||||||
| 8 | A0 | This is the Data/Command control pad that determines whether the data bits are data or a command. In I2C interface, this pad serves as SA0 to distinguish the different address of OLED driver. |
||||||||||||
| 9 | SCL | The serial clock input pad | ||||||||||||
| 10 | SI/SDA | The serial data input pad | ||||||||||||
| 11 | NC | Dummy Pin | ||||||||||||
| 12 | IREF | This is a segment current reference pad. A resistor should be connected between this pad and VSS. Set the current at 18.75μA. | ||||||||||||
| 13 | VCOMH | The pin is for COM signal deselected voltage level. A capacitor should be connected between this pin and VSS. |
