Hello uGFX community,
I'm absolutely new to uGFX - up to now I was just using some simple alphanumeric displays.
However, I've been working with ChibiOS for some years, so I would like to give the combination of a nice OS with a nice gfx lib a try :-)
For my first steps I chose this example:
I can compile it without error, however there are several warnings.
If I execute the hex, I get a blue screen with text "Calibration" and some kind of cursor which I have to press on the touchscreen.
After pressing, the cursor shows at another position:
1. Uppler left corner
2. Upper right corner
3. Lower right corner
4. Center of screen
After having pressed the center cursor, the cursor disappears, but nothing happens. The screen still shows "Calibration".
I guess this calibration takes place somewhere in the uGFX initialization function. Because when I look into main.c, there is nothing about calibration, but a lot of text and graphics drawing, which does not seem to be executed in my case. Also there is no blinking LED on the board.
Is there a technical problem, or did I just not understand how to use the example? Any other screen position or hardware button which I have to press to leave the calibration?
Thanks for your help!
Tobias
