+# arduino-esp32-led-blink-sdk
+
+This example demonstrates how to integrate with the ESP-IDF SDK via CMake and how to use the Arduino GPIO library to control an LED from Swift. This example is specifically made for the RISC-V MCUs from ESP32 (the Xtensa MCUs are not currently supported by Swift).
+
+## Requirements
+
+- Set up **version v5.4** (required for this `arduino-esp32` version) of the [ESP-IDF](https://docs.espressif.com/projects/esp-idf/en/v5.4/esp32/) development environment. Follow the steps in the [ESP32-C6 "Get Started" guide](https://docs.espressif.com/projects/esp-idf/en/v5.4/esp32c6/get-started/index.html).
+  - Make sure you specifically set up development for the RISC-V ESP32-C6, and not the Xtensa based products.
+  - If you have a different version of ESP-IDF installed, make sure to also delete `~/.espressif` before running `install.sh`
+
+```sh
+rm -rf ~/esp-idf ~/.espressif # Remove old installation files
+git clone --recurse-submodules https://github.com/espressif/esp-idf.git ~/esp-idf
+cd ~/esp-idf
+git checkout release/v5.4
+git submodule update --init --recursive
+./install.sh
+idf_tools.py install-python-env
+. ./export.sh
+```
+
+- Before trying to use Swift with the ESP-IDF SDK, make sure your environment works and can build the provided C/C++ sample projects, in particular:
+  - Try building and running the "get-started/blink" example from ESP-IDF written in C.
+
+## Building
+
+- Make sure you have a recent nightly Swift toolchain that has Embedded Swift support.
+- If needed, run export.sh to get access to the idf.py script from ESP-IDF.
+- Specify the nightly toolchain to be used via the `TOOLCHAINS` environment variable and the target board type by using `idf.py set-target`.
+```sh
+cd arduino-esp32-led-blink-sdk
+export TOOLCHAINS=...
+. <path-to-esp-idf>/export.sh
+idf.py set-target esp32c6
+idf.py build
+```
+
+## Running
+
+- Connect the Esp32-C6-Bug board (or any other board with integrated LED on GPIO pin 8) over a USB cable to your Mac. Alternatively you can just connect external LED to GPIO pin 8 on any other board.
+- Connect RX pin of USB-UART converter to TX0 pin of your board if you need serial output. You may also need to connect GND converter pin to the GND pin of the board.
+- Use `idf.py` to upload the firmware and to run it:
+
+```sh
+idf.py flash
+```
+
+- The LED should be blinking now.
+
+### Simulating in VS Code
+
+- Build the project, to generate binaries for simulation
+- Install [Wokwi for VS Code](https://docs.wokwi.com/vscode/getting-started/).
+- Open the `diagram.json` file.
+- Click the Play button to start simulation.
+- Click the Pause button to freeze simulation and display states of GPIOs.
