How to use Labview CE 2020/2021 to write to an LCD Display with an Arduino

[PaulyG123]

Hey all,

I've been trying to figure out how to use LabVIEW Community Edition 2020 (or 2021) to write text to a 16x2 or 20x4 LCD display wired to an Arduino Uno or Mega. Can anyone point me to a tutorial, website, or any information on this. I've been searching for days but can't seem to find the right info.

My displays have the I2C/SPI daughter boards, but I can run without the I2C/SPI board. I've tried to run the LIFA code shown below without the I2C, but the text fails to print to the LCD. Somehow, I think there needs to be a sketch uploaded to the Arduino to interface LIFA code with Labview. The LINX Firmware Wizard doen't seem to support LIFA.

I'd rather do it with LINX using I2C/SPI as I believe LIFA is relatively old at this point. Any help would be appreciated.
