# LTC230x
Arduino library for LTC230x ([LTC2301](https://www.analog.com/en/products/ltc2301.html), [LTC2305](https://www.analog.com/en/products/ltc2305.html), and [LTC2309](https://www.analog.com/en/products/ltc2309.html)) 12-Bit ADCs with I2C Interface
## Usage
```cpp
#include
#include
ltc230x::LTC230x ltc2309;
void setup()
{
Wire.begin();
using namespace ltc230x;
ltc2309.begin(Wire, address::AD1_LOW_AD0_LOW);
ltc2309.set_channel(channel::POSITIVE_0_NEGATIVE_1);
ltc2309.set_unipolar_bipolar_mode(uni_bi::UNIPOLAR);
ltc2309.set_sleep_mode(sleep::WAKE);
}
void loop()
{
uint16_t raw_data = ltc2309.read_raw();
int16_t adc_data = ltc2309.read();
float voltage = ltc2309.read_voltage();
// Use read data
}
```
## APIs
```cpp
/// @brief Initialize the LTC230x
/// @param wire TwoWire object
/// @param addr LTC230x I2C address
void begin(TwoWire &wire, address::Address addr);
/// @brief Read raw 16bit data from the LTC230x
/// @return Raw unsigned 16bit data
uint16_t read_raw();
/// @brief Read signed 12bit ADC data from the LTC230x
/// @return Signed 12bit ADC data
int16_t read();
/// @brief Read voltage from the LTC230x
/// @return Voltage [V]
float read_voltage();
/// @brief Set the LTC230x I2C address
/// @param addr LTC230x I2C address
void set_address(address::Address addr);
/// @brief Set the LTC230x channel
/// @param channel LTC230x channel

/// @brief Set the LTC230x unipolar/bipolar mode
/// @param uni_bi LTC230x unipolar/bipolar mode

/// @brief Set the LTC230x sleep mode
/// @param sleep LTC230x sleep mode
