für eine kontinuierliche grafische Anzeige von Messwerten suche ich eine Möglichkeit, das Hardware-Scrolling des ILI9341-Ansteuer-IC zu nutzen. In den Bibliotheken bin ich nicht fündig geworden. Hier das Display:
For a continuous graphic display of measured values, I am looking for a way to use the hardware scrolling of the ILI9341 control IC. I didn't find anything in the libraries. Here is the display:
It is always wise to post a link to the actual display that you bought.
And to quote which library and library example sketch(es) you have tried.
Most TFT controllers can do hardware scrolling e.g. ILI9341.
but the ST7781 has a bug (if you enable the undocumented vertical scroll)
The AZDelivery link is untrue. There is no XPT2046.
The BangGood link might contain different TFT controllers.
Anyway, please install the MCUFRIEND_kbv library via the IDE Library Manager.
It will work with most TFT controllers (more than Adafruit_TFTLCD)
Please check the ID that is reported. e.g. 0x9341, 0x9340, 0x9325, ...
And it has examples that show vertical scrolling.
Read Registers on MCUFRIEND UNO shield
controllers either read as single 16-bit
e.g. the ID is at readReg(0)
or as a sequence of 8-bit values
in special locations (first is dummy)
