# ESP32_IO_Expander
ESP32_IO_Expander is an Arduino library designed for driving [IO expander chips](#supported-drivers) using ESP32 SoCs.
ESP32_IO_Expander encapsulates various components from the [Espressif Components Registry](https://components.espressif.com/). It is developed based on [arduino-esp32](https://github.com/espressif/arduino-esp32) and can be easily downloaded and integrated into the Arduino IDE.
## Features
* Supports various IO expander chips.
* Supports controlling individual IO pin (using pinMode(), digitalRead(), and digitalWrite() functions).
* Supports controlling multiple IO pins simultaneously.

### Detailed Usage
```cpp
#include <ESP_IOExpander_Library.h>
// Create an ESP_IOExpander object according to the chip type
ESP_IOExpander *expander = new ESP_IOExpander_TCA95xx_8bit(EXAMPLE_I2C_NUM_0, ESP_IO_EXPANDER_I2C_TCA9554_ADDRESS_000,
EXAMPLE_I2C_SCL_PIN, EXAMPLE_I2C_SDA_PIN);
// Control a single pin (0-31)
expander->pinMode(0, OUTPUT);
expander->digitalWrite(0, HIGH);
expander->digitalWrite(0, LOW);
expander->pinMode(0, INPUT);
int level = expander->digitalRead(0);
// Control multiple pins (IO_EXPANDER_PIN_NUM_0 - IO_EXPANDER_PIN_NUM_31)
expander->multiPinMode(IO_EXPANDER_PIN_NUM_0 | IO_EXPANDER_PIN_NUM_1, OUTPUT);
expander->multiDigitalWrite(IO_EXPANDER_PIN_NUM_0 | IO_EXPANDER_PIN_NUM_1, HIGH);
expander->multiDigitalWrite(IO_EXPANDER_PIN_NUM_0 | IO_EXPANDER_PIN_NUM_1, LOW);
expander->multiPinMode(IO_EXPANDER_PIN_NUM_0 | IO_EXPANDER_PIN_NUM_1, INPUT);
uint32_t level = expander->multiDigitalRead(IO_EXPANDER_PIN_NUM_2 | IO_EXPANDER_PIN_NUM_3);
// Release the ESP_IOExpander object
delete expander;
