Arduino serial data read/write.

---

Hello ,

Is there a plugin to read the serial port data available?I’m not interested in 433/866 or all other wireless communication.Just reading the serial port from an arduino and listen for predefined data stream in the config.

Thank’s in advance .

if you can write the serial port data to a logfile you could either read the data via logreader (depending on what data you want to display) or you could use the iframe plugin to display the logfile for example.

Clarification: Johnny-Five builds on Firmata, which is a general pupose Protocol (and Arduino Sketch) for programmatic interaction with Arduino and Arduino compatible development boards. See also https://github.com/firmata/arduino#usage. According to the usage outline, for JohnnyFive you would normally use the general purpose Sketch, e.g. StandardFirmata, and tell JohnnyFive how to interact with the board, e.g. which Pins to read/write, or which devices to interact with as there are numerous abstractions for analog and digitals sensors and actuators available.

If you cannot adapt to this model and you have a specific Arduino sketch to deal with, perhaps the approach outlined by @leader21 will be suitable for you. Another approach would be to write your own serialport driver based on node-serialport. This is also used for various pimatic plugins. For example, you can have a look at pimatic-homeduino where the serialport driver is implemented in an subordinate project: https://github.com/pimatic/homeduinojs. See board.coffee and serialport.coffee in the src folder.
