Friends, I have a TFT with 2.2SP ili9341 (even that has nid69ita) working on nano and I can make it work with the sketch below (using 22k resistors instead of using cd4050). I tried to use the librarie suggested by chisco and pinout suggested by nid69ita and then the TheCoolest and none of them worked. Can anyone help me?
/*==========================================================================
The LCD connection is the same as Nokia LCD5110 and is a?? Bit Pant Demo??
Just for ElecFreaks TFT01-2.2SP, which use SPI serial port and 240x320 pixel.
The driver is ILI9341.
