Does this library support M5Core2?

[Bodmer]

No

The M5Core2 Library uses an old version of TFT_eSPI at it;s core so it should be possible to move the relevant setup files over. I am busy at the moment but will look to see if this is possible next week.

As far as I can tell the ILI9342C is directly compatible with the existing ILI9341 driver, except that it starts up in landscape mode. The library already has the required support. A suitable setup file for the M5Core2 is below. It appears the M5Core2 does not have a backlight control pin. Post back if the backlight LED does not illuminate, or the setup file does not work. I do not have an M5Core2 to test.

#define ILI9341_DRIVER

#define TFT_SDA_READ

#define M5STACK             // Adapts ILI9341 driver for the ILI9342C rotation

#define TFT_MISO 38
#define TFT_MOSI 23
#define TFT_SCLK 18
#define TFT_CS   5       // Chip select control pin
#define TFT_DC   15     // Data Command control pin
#define TFT_RST  -1     // Reset pin (could connect to Arduino RESET pin)
#define TFT_BL   -1      // LED back-light (required for M5Stack)

#define LOAD_GLCD   // Font 1. Original Adafruit 8 pixel font needs ~1820 bytes in FLASH

#define LOAD_FONT4  // Font 4. Medium 26 pixel high font, needs ~5848 bytes in FLASH, 96 characters
#define LOAD_FONT6  // Font 6. Large 48 pixel font, needs ~2666 bytes in FLASH, only characters 1234567890:-.apm

#define LOAD_GFXFF  // FreeFonts. Include access to the 48 Adafruit_GFX free fonts FF1 to FF48 and custom fonts

// Comment out the #define below to stop the SPIFFS filing system and smooth font code being loaded

// #define SPI_FREQUENCY  27000000 // Actually sets it to 26.67MHz = 80/3

Ah I see the backlight and display power is controlled by a different chip and the TFT_eSPI library does not have a driver for it:

If you wish to use the M5Core2 I will have to add a driver or a separate function for the sketch.

[Bodmer]

There is an Arduino AXP192 library that could be used to manage the TFT power. However you would need to look in more detail at what other functions in the M5Core2 are connected to the chip and whether these need to be controlled. The M5Core2 also has a capacitance touch controller so again you would have to look for a library.

Since the M5Core2 library has an early version of TFT_eSPI embedded within it (it has been renamed In_eSPI), the simplest solution is to use that dedicated library.

@fermintm Thanks for your kind offer of an M5Core2. I have too many projects on the go to make use of one at the moment, so must decline.
