initial code for 2.08-inch small oled display
Customize the length, width and thickness of FPC or cable, adjust the pin arrangement according to the interface type, and select the appropriate connector. Make your display or circuit board simple and safe with an excellent FPC solution.
A touch screen can be added according to your requirements, there are three options: resistive touch screen, capacitive touch screen, infrared touch screen. Or add protective glass as needed
Display screens with different optical parameters can be designed according to needs, such as brightness, color gamut, response time, gamma and other parameters, and anti-glare, anti-fingerprint coatings, etc. can also be added
The circuit board we designed can convert the interface of your display into an HDMI interface. If your product does not have any display control capabilities, you can use our serial display and only need to use simple commands to control the displayed content through RS232/458
2.08-inch OLED Display drawings and interfaces
2.08-inch monochrome OLED display with a resolution of 256×64, displaying white content, the driver IC is SH1122, and supports 3-wire/4-wire serial interface. The display FPC adopts welding FPC, which supports length, interface definition and shape customization.
The outline drawing is as follows:
Interfaces are defined as follows：
| Pin | Symbol | Detail |
| 1 | VSS | GND |
| 2 | BS2 | Communication interface selection |
| 3 | BS1 | Communication interface selection |
| 4 | BS0 | Communication interface selection |
| 5 | NC | |
| 6 | VCC | Power supply for panel driving voltage |
| 7 | VCOMH | |
| 8 | IREF | This is segment output current reference pin. A resistor should be connected between this pin and VSS to maintain the IREF current at 10uA |
| 9 | D7 | These are 8-bit bi-directional data bus to be connected to the microprocessor’s data bus. 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. |
| 10 | D6 | |
| 11 | D5 | |
| 12 | D4 | |
| 13 | D3 | |
| 14 | D2 | |
| 15 | D1 | |
| 16 | D0 | |
| 17 | E(RD) | When interfacing to a 6800-series microprocessor, this pin will be used as the Enable (E)signal. Read/write operation is initiated when this pin is pulled HIGH (i.e. connect to VDD)and the chip is selected. When connecting to an 8080-series microprocessor, this pin receives the Read (RD#)signal. Read operation is initiated when this pin is pulled LOW and the chip is selected. When serial interface is selected, this pin must be connected to VSS |
| 18 | R/W | This is read / write control input pin connecting to the MCU interface. When interfacing to a 6800-series microprocessor, this pin will be used as Read/Write (R/W#) selection input. Read mode will be carried out when this pin is pulled HIGH (i.e.connect to VDD) 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. |
| 19 | D/C | This is Data/Command control pin. When it is pulled HIGH (i.e. connect to VDD), the data at D[7:0] is treated as data. When it is pulled LOW, the data at D[7:0] will be transferred to the command register. In I2C mode, this pin acts as SA0 for slave address selection. When 3-wire serial interface is selected, this pin must be connected to VSS. |
| 20 | RES | This pin is reset signal input. When the pin is pulled LOW, initialization of the chip is executed. Keep this pin HIGH (i.e. connect to VDD) during normal operation |
| 21 | CS | this pin is the chip select input. (active LOW) |
| 22 | VDD | Power supply pin for core logic operation. |
| 23 | NC | |
| 24 | VSS | GND |
