ADS7830 Arduino Library

This is an Arduino library for interfacing with the ADS7830, an 8-channel 8-bit A/D converter with an I2C interface.

Features

• Read ADC values from any of the 8 single-ended channels.
• Read ADC values from all channels at once.
• Simple and easy-to-use API.

Installation

1. Download the library as a ZIP file.
2. In the Arduino IDE, go to Sketch -> Include Library -> Add .ZIP Library...
3. Select the downloaded ZIP file and click Open.

Usage

Include the Library

Include the ADS7830 library in your sketch:

#include <ADS7830.h>

Create an ADS7830 Object

Create an instance of the ADS7830 class:

ADS7830 adc;

Initialize the ADC

Initialize the I2C communication and the ADS7830 ADC in the setup() function:

void setup() {
    Serial.begin(9600);
    adc.init(); // Initialize with baudrate
}

Read ADC Values

Read the ADC value from a specific channel:

void loop() {
    uint8_t value = adc.readChannel(0); // Read from channel 0
    Serial.print("Channel 0: ");
    Serial.println(value);
    delay(1000); // Wait for a second before the next read
}

Read ADC values from all channels:

void loop() {
    uint8_t values[8];
    adc.readAllChannels(values);

    for (uint8_t i = 0; i < 8; i++) {
        Serial.print("Channel ");
        Serial.print(i);
        Serial.print(": ");
        Serial.println(values[i]);
    }
    delay(1000); // Wait for a second before the next read
}

Custom I2C Settings

You can customize the I2C SDA and SCL pins and the baudrate when initializing the ADC:

void setup() {
    Serial.begin(9600);
    adc.init(400000); // SDA, SCL = default port, baudrate = 400kHz
}

API Reference

Constructor

• ADS7830(uint8_t i2cAddress = 0x48)
  • Creates an ADS7830 object.
  • i2cAddress: The I2C address of the ADS7830 (default is 0x48).

Initialization

• void begin(uint32_t baudrate = 100000)
  • Initializes the I2C communication and ADS7830 ADC.
  • baudrate: The I2C baudrate (default is 100000).

Reading ADC Values

• uint8_t readChannel(uint8_t channel)

  • Reads the ADC value from a specific channel.
  • channel: The ADC channel to read (0-7).
  • Returns the ADC reading (0-255).

• void readAllChannels(uint8_t* values)

  • Reads ADC values from all channels and stores them in an array.
  • values: Array to store the ADC readings (must be at least 8 elements).
