I have what I think is a LCD-14073 SERLCD display, and the basic functions work ok for me. However, I’m not sure I have access to everything I can do with it. The question I have concerns the (2) libraries on GitHub. Depending on where I click in your guide, I go to either OPENLCD library or the SparkFun\_SerLCD\_Arduino\_Library. Which library should I be using for the 14073 in i2c mode and in the serial mode? Thanks! ---

The OpenLCD firmware is for the LCD itself. The SerLCD is for Arduino. If you only need to get your Arduino working with the LCD, you only need to use the SerLCD library. ---

I have the same issue, but I’m trying to use a Raspberry Pi… I found a 3rd party Python library on github, but there’s a documented problem that there is a timing error that keeps crashing my python program. I’m hoping because of your refernce to OPENLCD that there might be another library I can use? I am using i2c through a QWIIC board… Thanks in advance!
