This is an Raspberry Pi only I2C bus socket packet listener and I2C bus master processor. See /examples/bus.js for how to implement an instance. The rest of the examples are client examples that will talk to a running i2c-bus instance
|
|
|
|
Here is a simple script to get an instance going (on an RPI only)
|
|
|
|
```
|
|
/*
|
|
* Raspberry Pi (only) I2C-Bus listener
|
|
* named pipe socket 'i2c-bus' is always created by default /tmp directory unless
|
|
* env variable SOCKETS_DIR='' is used to create a 'i2c-bus.sock' in a particular directory
|
|
* e.g. command >SOCKETS_DIR=/opt/sockets node -r esm i2cbus
|
|
* add TCP listener with tcp:true. Will listen on port 1776 by default
|
|

import Bus from '@uci/i2c-bus'
|
|
;
|
|
(async () => {
|
|
|
|
let i2cbus = new Bus({id:'i2c-bus',tcp:true})
|
|
|
|
await i2cbus.init()
|
|
|
|
})().catch(err => {
|
|
console.error('FATAL: UNABLE TO START SYSTEM!\n',err)
|
|
})
