OpenI2C

This library is a set of cross platform drivers for common I2C devices using i2c-bus.

Prerequisites

• Ensure that i2c is enabled on your device.

Module Drivers

• PCA9685 - A 16 channel pulse width modulation module.

Using A Driver

You can import the driver by the module name, directly from the openi2c package.

For detailed usage of each driver, click on the module name in the section above.

import { PCA9685 } from 'openi2c';
const pwmDriver = new PCA9685();
await pwmDriver.setFrequency(50);
await pwmDriver.setDutyCycle(0, 0.5);

Utilities

The library exports some utility functions that are used by internal drivers and can be useful for developers using these drivers.

import { sleep, mapValue } from 'openi2c';
await sleep(100); // Sleeps for 100ms
mapValue(50, 0, 100, 0, 1) // Maps 50 in range 0 - 100 to range 0 - 1, result: 0.5
