Spi communication problem help me !?

[skyy_tsuki]

Hello, i'm french and im actually using the FT81x_Arduino_Driver, library and my problem is when i put all the good pin and put the exemple code hello world there nothing on the screen, the screen stay black.

So in first i'm using the nhd-7.0-800480FT-CTXL-T with an arduino zero.
I want to know if it's possible to work with this screen and that arduino card ?

My connection pin are

• SCK : 13
• MOSI : 12
• MISO : 11
• SS : 10
  all conected to the screen the screen is on 3,3 volt same for the backlight.
  FT81x_Arduino_Driver.zip (1,1 Mo)
  And this is the datasheet of the screen
  NHD-7.0-800480FT-CTXL-T.pdf (1,4 Mo)
  And i'm using that code

#include "FT81x.h"

// Define pin connections for Arduino Zero
const uint8_t FT81X_CS = 10;    // Chip Select
const uint8_t FT81X_PD = 9;     // Power Down
const uint8_t FT81X_INT = 8;    // Interrupt

FT81x ft81x = FT81x(FT81X_CS, FT81X_PD, FT81X_INT);

void setup() {
    SPI.begin();
    ft81x.begin();
    
    ft81x.setRotation(FT81x_ROTATE_LANDSCAPE);

    ft81x.beginDisplayList();
    ft81x.clear(FT81x_COLOR_RGB(255, 255, 255));
    ft81x.drawText(240, 150, 31, FT81x_COLOR_RGB(0, 0, 0), FT81x_OPT_CENTER, "Hello World\\0");
    ft81x.drawText(240, 210, 22, FT81x_COLOR_RGB(0, 0, 0), FT81x_OPT_CENTER, "https://github.com/blazer82/FT81x_Arduino_Driver\\0");
    ft81x.drawCircle(120, 350, 40, FT81x_COLOR_RGB(255, 0, 0));
    ft81x.drawCircle(240, 350, 40, FT81x_COLOR_RGB(0, 255, 0));
    ft81x.drawCircle(360, 350, 40, FT81x_COLOR_RGB(0, 0, 255));
    ft81x.swapScreen();
}

void loop() {
    // do nothing
}

"Hello World\\0"

Have you tried putting a single backslash ?

"Hello World\0"
