This is a simplified example of using the tjpgd and also libnsgif to decode JPEG and GIF images, and display them on an LCD screen.
- An ESP-C6 development board
- An SPI-interfaced LCD screen (ST7789)
- An USB cable for power supply and programming
The connection between ESP Board and the LCD is as follows:
ESP Board LCD Screen
+---------+ +---------------------------------+
| | | |
| GND +--------------+ GND +----------------------+ |
| | | | | |
| 3V3 +--------------+ VCC | | |
| | | | | |
| 19 +--------------+ SCL | | |
| | | | | |
| 18 +--------------+ SDA | | |
| | | | | |
| 10 +--------------+ RES | | |
| | | | | |
| 11 +--------------+ DC | | |
| | | | | |
| 2 +--------------+ BCKL +----------------------+ |
| | | |
+---------+ +---------------------------------+
The GPIO numbers used by this example can be changed in main.h, where:
| GPIO number | LCD pin |
|---|---|
| ST7789_PIN_NUM_PCLK | SCL |
| ST7789_PIN_NUM_DC | DC |
| ST7789_PIN_NUM_RST | RES |
| ST7789_PIN_NUM_DATA0 | SDA |
| ST7789_PIN_NUM_BK_LIGHT | BCKL |
Run idf.py -p PORT flash monitor to build, flash and monitor the project. The JPG logo picture will be shown on the LCD screen. After 3 seconds, the picture will be changed to the annimated GIF picture.
(To exit the serial monitor, type Ctrl-].)
