updated library UTFT version 2.1 with a CTE shield

I was able to download the complete drivers. I tested the drivers using both the "default_shield" and "CTE_shield" switch. I could not find any difference between the two functions, both were displayed the same, "mirrored", and is unreadable.

I am using the CTE DUE shield + CTE 7" display "CTE70".

What is supposed to be the benefit of using one or the other switches, and how can I tell if it's working properly.

Thank you for your effort, but as of yet I cannot see any benefit to your drivers.
