After I could evaluate/test many features on Portenta H7, mbed, Arduino ... (please do not ask for my general conclusion 
)
I try to use the USB-C Display now.
Even there seem to be some code examples, e.g. "Portenta_lvgl.ino" - nothing works.
It ends up all the time that the file
#include "lvgl.h"
is not found.
This is used also by code example "lv_demo_widgets".
I have also an Arduino mbed Portenta H7 GIT hub repository copy - also missing there.
Where is the code for USB-C Display?
Please,
who does have a simple USB-C display video demo project?
which can be compiled? I appreciate.
My intention:
I want to have a very simple USB-C display, e.g. just plain text (no widgets, no mouse). Just display the same text as displayed via UART (to terminal) - a simple text display on external monitor.
I want to see the USB-C video bridge (DSI, MIPI), via U6 (ANX7625), working.
Right now: the HW which I have bought does not do what it was promised to do.
(a legal claim issue to get my money back?)
Where are the LIB functions?
What is the simplest test/demo for USB-C Display?
Will it work via a USB-C hub, so that I keep my power via USB-C, the UART connection to host (for terminal) and a separate USB-C monitor connected?
(there must be an external USB-C - does it work, has anybody tried? Three devices on USB-C (bootloader, UART, Display ...)? Possible?
Why Arduino (mbed - I do not care who is who - it comes as "mbed"...) does not provide a simple and working example? (for USB-C Display)
Why we had to figure out all features our own way?
(and will come up with a not so nice summary?)
After all my experience: "mbed" is not 'so usable'.
Why is this board promoted as "for professional" and "industrial" use - when it is not really at the end?
I bought this board especially for these features! Now it turns out that some of the promoted features are not possible (USB-C Display = no clue how?, QSPI not possible for code execution!) - should I take my fingers from this board (even I would need for a professional, commercial use but it is not supported/intended at the end - Arduino company does not provide help via its forum...)?
Dear Arduino team
please make sure that all what you promise is working! For all features you mention in datasheet which resulted in my purchase decision - is true and really possible to use!
Thank you.
