Arduino Zero, The screen remains blank. Display East Rising ER-TFTM035-6 (ILI9488 4Wire SPI) Work well using other library.

define TFT_CS A5

define TFT_DC 10

define TFT_RST 26

ILI9488 tft = ILI9488(TFT_CS, TFT_DC, TFT_RST);

Looking at the signals with an oscilloscope, they are all correct. Except that MISO has only a small boost.
