MCLKSEL = 0; The XPT2046 is a classic successive approximation register (SAR) analog-to-digital converter (ADC). * when the stylus is moved to fast, "ghost" points appear in tpdraw Library for ILI932x display controllers and common resistive touch screen controllers like XPT2046, ADS7843, etc. getPositionAvg() print(x . y) xpt2046. I don't have a logic analyser or another module to try unfortunately. XPT2046_Touchscreen is a library for the XPT2046 resistive touchscreen controllers used on many low cost TFT displays. However, on the ESP8266, unless the SPI bus is shared, there aren't enough pins for both the LCD and the touchscreen. The only differences are the screen dimensions and the initialisation code. Other than that I'm all out of ideas. /usr/bin/matrix-setqt4env $ / usr/local/Trolltech/QtEmbedded-4. h header file so it isn't always in the way. 90a environment. 5 touch screen, a XPT2046 Touch Controller, to work on Raspberry!
