_This example uses the ESP8266 hspi Master to drive 2.7-inch SPI ILI9341, and the LCD driver chip is ILI9341. And I transplant the lvgl into the project _
1.Download sdk. ESP8266 SDK V3.0
- 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 |
make menuconfig
- Set serial port under Serial Flasher Options.
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.
