# ESP32 Swift Example
Example of graphical application for ESP32-C3, ESP32-P4.
Read more about Swift for ESP32 at [Espressif Developer Portal](https://developer.espressif.com/tags/swift/).
## On-line Demo Simulation
[](https://wokwi.com/experimental/viewer?diagram=https%3A%2F%2Fraw.githubusercontent.com%2Fgeorgik%2Fesp32-sdl3-swift-example%2Fmain%2Fboards%2Fesp32_p4_function_ev_board%2Fdiagram.json&firmware=https%3A%2F%2Fgithub.com%2Fgeorgik%2Fesp32-sdl3-swift-example%2Freleases%2Fdownload%2Fv1.0.0%2Fesp32-sdl3-swift-example-esp32_p4_function_ev_board.bin)
[Run the ESP32-P4 SDL3 Swift with Wokwi.com](https://wokwi.com/experimental/viewer?diagram=https%3A%2F%2Fraw.githubusercontent.com%2Fgeorgik%2Fesp32-sdl3-swift-example%2Fmain%2Fboards%2Fesp32_p4_function_ev_board%2Fdiagram.json&firmware=https%3A%2F%2Fgithub.com%2Fgeorgik%2Fesp32-sdl3-swift-example%2Freleases%2Fdownload%2Fv1.0.0%2Fesp32-sdl3-swift-example-esp32_p4_function_ev_board.bin)
## Requirements
- Swift 6.1 - https://www.swift.org/install
- ESP-IDF 5.4 - https://github.com/espressif/esp-idf
## Build
### Configure build environment
```shell
source esp-idf/export.sh
export TOOLCHAINS=$(plutil -extract CFBundleIdentifier raw /Library/Developer/Toolchains/swift-DEVELOPMENT-SNAPSHOT-2024-10-30-a.xctoolchain/Info.plist)
```
### Build for ESP32-P4-Function-Ev-Board
```shell
idf.py @boards/esp32_p4_function_ev_board.cfg flash monitor
```
### Build for ESP32-C3-LcdKit
```shell
idf.py @boards/esp32_c3_lcdkit.cfg flash monitor
```
### Build for ESP32-C6-DevKit
The configuration of this board is based on [ESP-BSP Generic](https://developer.espressif.com/blog/using-esp-bsp-with-devkits/) which allows configuration using menuconfig.
SPI Display configuration:
```ini
CONFIG_BSP_DISPLAY_ENABLED=y
CONFIG_BSP_DISPLAY_SCLK_GPIO=6
CONFIG_BSP_DISPLAY_MOSI_GPIO=7
CONFIG_BSP_DISPLAY_MISO_GPIO=-1
CONFIG_BSP_DISPLAY_CS_GPIO=20
CONFIG_BSP_DISPLAY_DC_GPIO=21
CONFIG_BSP_DISPLAY_RST_GPIO=3
CONFIG_BSP_DISPLAY_DRIVER_ILI9341=y
```
You can change the configuration by running:
```shell
idf.py @boards/esp32_c6_devkit.cfg menuconfig
```
```shell
idf.py @boards/esp32_c6_devkit.cfg flash monitor
```
### Build for Waveshare ESP32-C6-LCD-1.47
- board: [ESP32-C6-LCD-1.47](https://www.waveshare.com/esp32-c6-lcd-1.47.htm)
- display: 172x320
```shell
idf.py @boards/waveshare-esp32-c6-lcd-1.47.cfg flash monitor
```
### Run simulation in VS Code
- Build the project, to get binaries for simulation.
- Install [Wokwi for VS Code](https://docs.wokwi.com/vscode/getting-started/).
- Open file `boards/esp32_.../diagram.json`.
- Click Play button to start simulation.
- Click Pause button to freeze simulation and display states of GPIOs.
