Read Messages Using Serial Communications

Currently we use the Serial (Player Only) which gives you the option to send messages but not read.

Is there going to be the ability to add the functionality to read serial data in the future without the use of an I/O edge device? Or is this functionality able to be enabled on our account?

Hi @nvincent and Welcome to Tulip Community! :tada: :tulip:

Do you mind giving me a little more context about what you are using serial connection for (which devices/equipment are you connecting to, whats your use case?)

Sure. We are attempting to use an Arduino to send a number over serial for a pressure datalogger we have designed.

We currently use Arduinos to receive messages sent from Tulip to turn on lights to signal if an item is behind or complete. Sending messages from Tulip works great, just would like to receive messages into Tulip as well.

We have written code to take the data from the Arduino over serial and using Python write it to SQL so we know the device functions. However, it would be much more ideal to do everything inside of Tulip so we can easily tie the serial number and such to the data.

Gotcha!

In this case, there are two options to accomplish what you’re looking for:

  • You can use the serial driver (Using the Serial Driver) to read data from the Arduino device into Tulip apps.
  • You can use Node-RED to read data from the Arduino device over serial and store it in a Tulip table.
