I have a TFT01-2.2SP display. The LCD in the TFT01 is ILI9341. It's a 240 * 320 (resolution). In the software SPI with Pixels library it works. Is it possible to use hardware SPI? How to do it?

In an ideal case it would be sufficient to substitute

include <Pixels_SPIsw.h>

with

include <Pixels_SPIhw.h>

Does it work for you?

I did it! It works! My simple test code

include "Pixels_SPIhw.h"

include "Pixels_ILI9341.h"

Pixels pxs(240, 320);

void setup() { pxs.setSpiPins(13, 11, 7, 5, 6); // TFT01-2.2SP display ILI9341(SCK, MOSI, CS, RESET, DC) pxs.init(); pxs.setBackground(0, 0, 0); pxs.setColor(0, 255, 0); pxs.clear(); pxs.fillRectangle(10, 10, 100, 100); }

void loop() {

}

After loading the sketch does not work, but after the switch-off and turn on Arduino sketch works! Probably because the Arduino is powered by 3.3 volts.
