This is code for an lcd with touch pannel.touch panel ili9328, and compatible displays.i've uploaded an schematic for the spi mode to work. it uses a shift registerWhen in lcdMode=1 it is in spi mode. also spi mode uses q0 and q3 for i/o for touch pins. lcd using 2 pins is still buggy expect it to get better soon.when in lcdMode==0 just plug in display, change pinout to match and run. it runs in 8 bit mode.vidoe shows the dispay with code and the pinch zoom. it is a work in progress, but far enough along that people can use it.http://youtu.be/rLsRGStPWnghere are time tests take by this method:unsigned long timetest=micros(); //tested function (here its the meat)//end of function timetest=micros()-timetest; Serial.print("function name :"); Serial.println(timetest);it takes 43ms to do a full screen refresh currently. that is just shy of 24 times a second refresh! it takes to write a single pixel.32-44 us, depending on cached or uncashed. to write 324 pixels burst mode 2.8msto write alphanumeric char to display largest font 18ms smallest font 1.4msint number to str=60us(); //using itoa it will be 32us per conversiontouch speed with full sensitivity measure time: ~600us// not programed to yet, but can detect in as little as 10us
