## ESP32 Universal pin driver 🌍
> [!IMPORTANT]
> Currently supporting only Serial (USB) communication.
### ⚡ Commands
```c
operation:mode:pin:value?
```
**Operation** `[write, read]`
**Mode** `[digital, analog]`
**Pin** `uint8_t`
Safe GPIOs `[4, 13, 14, 16, 17, 18, 19, 21, 22, 23, 25, 26, 27, 32, 33, 34, 35, 36, 39]`.
Pin mapping [here](include/esp32_gpio_mapping.cpp).
**Value** `int`
Value is automatically clamped to 8 bit:`[0, 255]`.
> [!NOTE]
> In digital write, pin is set to high if the value is greater than 0.
Examples:
```c
write:digital:13:0
write:analog:25:128
read:digital:19
read:analog:33
```
The ESP32 board available pins depend on the operation and mode used. Check out [esp32_gpio_mapping.cpp](include/esp32_gpio_mapping.cpp) for pin availability. For detailed information, check out the [ESP32 Pinout](https://lastminuteengineers.com/esp32-pinout-reference/).
### 🧪 Testing
To test program using the [Python utility](serial_test.py), install `pyserial`:
```sh
pip install pyserial
```
The run the script:
```sh
python serial_test.py
```
To edit the Serial port, edit the following line in the script:
```py
ser = serial.Serial("
