I'm trying to activate the ILI9486 with the following pins.
The following is the code you can input into the "user_setup.h" file.
#define USER_SETUP_ID 70
#define ILI9486_DRIVER
#define TFT_PARALLEL_8_BIT
// ESP32 S3 pins used for the parallel interface TFT
#define TFT_CS 4
#define TFT_DC 37 // Data Command control pin - must use a GPIO in the range 0-31
#define TFT_RST 5
#define TFT_WR 13 // Write strobe control pin - must use a GPIO in the range 0-31
#define TFT_RD 11
#define TFT_D0 2 // Must use GPIO in the range 0-31 for the data bus
#define TFT_D1 1 // so a single register write sets/clears all bits
#define TFT_D2 8
#define TFT_D3 7
#define TFT_D4 4
#define TFT_D5 5
#define TFT_D6 6
#define TFT_D7 41
#define LOAD_GLCD // Font 1. Original Adafruit 8 pixel font needs ~1820 bytes in FLASH
#define LOAD_FONT2 // Font 2. Small 16 pixel high font, needs ~3534 bytes in FLASH, 96 characters
#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_FONT7 // Font 7. 7 segment 48 pixel font, needs ~2438 bytes in FLASH, only characters 1234567890:.
#define LOAD_FONT8 // Font 8. Large 75 pixel font needs ~3256 bytes in FLASH, only characters 1234567890:-.
#define LOAD_GFXFF // FreeFonts. Include access to the 48 Adafruit_GFX free fonts FF1 to FF48 and custom fonts
#define SMOOTH_FONT
I tried running clour.test, but it only turns the screen gray. I don't know what the problem is.
