# Board Support Package (esp-bsp component) modified for esp32-cam using ESP-IDF 5.3, 2,8" ili9341 LCD display and LVGL 9.x
Esp32-cam connected to 2.8" ili9341 LCD display using LVGL for video stream.
This project requires the esp-idf sdk 5.3.1.
## Display Pins
| Pin Number on ILI9341 Display | Pin Number on ESP32-cam |
| ------------ | ------------ |
| 3.3V | 3.3V |
| GND | GND |
| CS | 12 |
| RESET* | 2* |
| DC | 13 |
| MOSI | 15 |
| CLK | 14 |
| LED | 3.3V |
| MISO | NC |
* you can connect LCD RESET PIN directly to the EN/RESET PIN on esp32 MCU (see picture bellow).
## RESET PIN and GPIO33 access
ESP32 reset pin can be connected directly to the display's reset pin and so GPIO 2 can be used for other purposes.
The same goes for GPIO 33, for example for connecting a button or the touch screen controller XPT2046.
## LVGL configuration settings
#### You can choose to build with the default LVGL configuration settings from:
`idf.py menuconfig`
`Menu → Component config → LVGL configuration → Memory Settings:`
#### and:
```
Malloc functions source (Standard C functions malloc/realloc/free) --->
String functions source (Standard C functions memcpy/memset/strlen/strcpy) --->
Sprintf functions source (Standard C functions vsnprintf) --->
```
#### or change to custom
` LVGL's built in implementation ` settings *(included in ` sdkconfig.defaults ` )*:
```
(64) Size of the memory used by lv_malloc() in kilobytes (>= 2kB)
(0) Size of the memory expand for lv_malloc() in kilobytes
(0x0) Address for the memory pool instead of allocating it as a normal array
```
