HAL

HAL stands for Hardware Abstraction Layer. It's REST/WS abstraction for hardware capabilities for Linux based machines.

Prerequisites:

as Docker container, it needs to be run with next options to grant access:

 --net=host --privileged 

in other cases it needs to start under root user

REST

REST server listens on port 54331.

WebSockets

WS server listens on port 54332.

Get USB-to-Serial Web-socket Connection

This endpoint opens a message Web-socket connection to USB-to-Serial device. The messages and other commands sent over this Web-socket are specified here. It is the responsibility of the container to establish this connection and ensure it is running.

The PORT of USB-to-Serial device must be passed as part of the URL because otherwise it would have to be passed in the Web-socket connection itself and that would make associated connections with different devices rather difficult.

Endpoint
	ws://loocalhost:54332/hal/rs232/{PORT=dev/ttyusb0}
Response
	None - the Websocket will simply be opened successfully
Querystring Parameters
	PORT - the PORT of USB-to-Serial device to connect to via the Websocket connection
	(example shown here as '/dev/ttyusb0')
Signals from HAL to Client
	- op code 4: (single byte command) indicates connection to device was opened (it's an answer to connection open op
	code signal sent with configuration for opening connection to physical device); at this point HAL starts
	listening on data from connected device.
	- op code 6: indicates that HAL recieved some data from physical device (op code single byte followed by pure bytes
	of data recieved from device)
	- standart close frame: indicates that current connection was closed.
	    > status code 1000 with close frame : means that device normally closed connection
	    > status code 4000 with close frame : there was an exception, error will be passed in reason.
Signals from Client to HAL
       - op code 3: signals HAL to open connection to device with specified configuration in passed data (op code single
       byte followed by bytes of json configuration to open connection to device ); in case with USB-to-Serial: PORT
       property is required.
       - op code 5: signals HAL to send recieved data to connected device (op code single byte followed by pure bytes of
       data to send to device)
       - standart close frame: indicates that client wants to close current connection.
           > status code 1000 with close frame : means that device normally closed connection
           > status code 4000 with close frame : there was an exception, error will be passed in reason.
JSON Configuration for USB-to-Serial device

All available configuration properties:

  • 'port'(required to open connection)
  • 'baudrate'
  • 'bytesize'
  • 'parity'
  • 'stopbits'
  • 'timeout'
  • 'xonxoff'
  • 'rtscts'
  • 'dsrdtr'
  • 'write_timeout'
  • 'interbytetimeout'
  • 'datareadtimeout' (this property tells HAL to pause for specified timeout in seconds before reading data from buffer)

Example:

{ "port": "/dev/ttyUSB0" }
