sigrok-mini-server

Delivers data from sigrok supported devices via TCP/IP in JSON Format

Status

• early development stage
• only tested under linux
• hardly any error handling
• analog and digital sigrok packets supported

How to use (under Linux)

Libsigrok 0.5.1 does not work. Currently you need the git version of libsigrok.

On the first console ./sigrok-mini-server.py -d demo samplerate=1 ls On the second console nc localhost 8888

Every second you should see new data in json format

{"channels": ["A3"], "device": {"hash": ":Demo device::", "id": 0}, "A3": ["4.0"], "msgtype": "data"}
{"channels": ["A1"], "device": {"hash": ":Demo device::", "id": 0}, "A1": ["9.51056"], "msgtype": "data"}
{"channels": ["A0"], "device": {"hash": ":Demo device::", "id": 0}, "msgtype": "data", "A0": ["-10.0"]}
{"channels": ["A2"], "device": {"hash": ":Demo device::", "id": 0}, "A2": ["8.0"], "msgtype": "data"}

Commands in examples

Information about connected devices

Request:{ "cmd": "INFO" }

Response: You will receive a message with information about all connected devices. The value of the hash-attribute is used to identify the device in all messages related to the device

{
   "deviceinfo":[
      {
         "hash":":Demo device::",
         "settings":[
            {

Set Configs

e.g. The following command changes the samplerate to 10

Request: { "cmd": "set", "key": "samplerate", "value":"10", "hash":":Demo device::"}

Response: {"device": ":Demo device::", "msgtype": "value", "value": "10", "key": "samplerate"}

Get Configs

Request: { "cmd": "get", "key": "samplerate", "hash":":Demo device::"}

Response: {"device": ":Demo device::", "msgtype": "value", "value": "1", "key": "samplerate"}

Auto Get Config

Request: { "cmd":"autoget", "hash":"*", "key": "voltage_target", "interval": "500"}

Response: Get Config-Responses ever 500 ms

Multiple Devices

You can access more than one device

e.g.sigrok-mini-server.py -d demo samplerate=1 -d korad-kaxxxxp:conn=/dev/ttyACM0
