Communication Basics

With the LJM library, pretty much everything you might want to do with a device is accomplished by writing and/or reading some registers.  Look at the device's datasheet (T7 or T4) or the Modbus Map to determine what registers you need to write and read, then use eWriteName (or eWriteNames) to write the desired registers and eReadName (or eReadNames) to read the desired registers.

Instructions

  • Go to the T4 or T7 Quickstart Tutorial and follow the steps to install LabJack software and confirm basic operation.
  • Download/extract the .zip file attached at the top of this page.
  • Start the processing program.
  • Use the "File -> Open" dialog box to navigate to the extracted .zip folder and into one of the two examples. Open the *.pde file.
  • Press the "Play" button.

Further Resources

These examples are based off of the original work by Jason and sent to us in the forum topic processing-language. Further explanations and some ideas for distributing processing applications can be found on the forum topic as well. Jason's description and example .zip file is located in comments #3, #4, and #6.
