Hi @JohnC and @graykevinb,
I couldn’t answer before because the office was closed due to the holidays and I also was out these past weeks.
About the LCD code question, I use the one you have uploaded to github, but I also tried with some visual block for a course we got in July, and I get the same problem with both of them.
On the other hand, I run two different OS with the RaspberryPi + GrovePi: 1) Cisco Image that provided to us in order to explain the IoT course and 2) the Raspbian OS that it can be found in: https://www.raspberrypi.org/downloads/raspbian/.
Finally, I realized the complete test, and the results are attached in the three .txt that I provide (they are uploaded as a single txt file because the forum says that new user just can upload one file, and zips are not admitted).

Thank you and we are on touch for any indication you can give.
