Hello,
The problem I met is the above display would be something like ON / OFF or SLEEPIN / SLEEPOUT.
The used controller ILI9341 should be able to do that. There is no SPI or I2C used but 8 data lines.
The following commands are defined in registers.
………...
#define ILI9341_SOFTRESET 0x01
#define ILI9341_SLEEPIN 0x10
#define ILI9341_SLEEPOUT 0x11
#define ILI9341_NORMALDISP 0x13
#define ILI9341_INVERTOFF 0x20
#define ILI9341_INVERTON 0x21
#define ILI9341_GAMMASET 0x26
#define ILI9341_DISPLAYOFF 0x28
#define ILI9341_DISPLAYON 0x29
.................
So how would / could I send a 0x10, for example?
