By the way, I got an oscilloscope with a dead vertical bar on the touchscreen, was broken (defective), one of the channels ITO gt911, I was able to find a replacement only gt915, pinout and features they are the same based on the datasheet, but in default configuration, ITO channels gt915 are in reverse order so the touchscreen works in a mirror mode, reconfiguration of channels and use the Chinese version of the firmware corrects this situation. The easiest way for those who have the touchscreen with gt915, find and solder gt911 (at the moment I managed to find and gt911). But to find and fix the part of the code that is engaged in reconfiguration for me is a matter of principle.
