# _SPI OLED Example_
|
|
|
|
_This example uses the ESP8266 hspi Master to drive 0.96-inch SPI OLED, and the OLED driver chip is SSD1306._
|
|
|
|
## How to use example
|
|
|
|
### Hardware Required
|
|
|
|
* Connection:
|
|
|
|
| Signal | Oled | ESP8266|
|
|
|-----------|--------|--------|
|
|
| 3.3V | VCC | VCC |
|
|
| SCLK | D0(SCL)| GPIO14 |
|
|
| D/C | DC | GPIO12 |
|
|
| MOSI | D1(SDA)| GPIO13 |
|
|
| RST | RES | GPIO15 |
|
|
| CS | CS | GND |
|
|
| GND | GND | GND |
|
|
|
|
### Configure the project
|
|
|
|
```
|
|
make menuconfig
|
|
```
|
|
|
|
* Set serial port under Serial Flasher Options.
|
|
|
|
|
|
### Build and Flash
|
|
|
|
Build the project and flash it to the board, then run monitor tool to view serial output:
|
|
|
|
```
|
|
make -j4 flash monitor
|
|
```
|
|
|
|
(To exit the serial monitor, type ``Ctrl-]``.)
|
|
|
|
See the Getting Started Guide for full steps to configure and use ESP-IDF to build projects.
