I am trying to use this library with Waveshare 1.69 inch lcd module (240x280).https://www.waveshare.com/1.69inch-lcd-module.htm
Board : Esp32 S3 DevKit C-1 N16R8
Unlike the previous display modules i have used, this has different pins as below image.
Connections :
Vcc - 3.3v
gnd - gnd
Din - considered as MOSI (35)
CLK - considered as SCLK (36)
CS - 7
DC - 15
RST - -1
BLK - none

Can someone pls help me regarding this. I had no luck.
I'm using latest version of the library and testing with Colour_Test code.

The below is my User_Setup.h file, i have tried different combinations but could not get it to work.

// For RP2040 processor and SPI displays, uncomment the following line to use the PIO interface.

// For RP2040 processor and 8 or 16 bit parallel displays:

// speed so scales with the processor clock. This means that the divider ratio may need

// display controller type (ILI94341, HX8357C etc). If RP2040_PIO_CLK_DIV is not defined
// the library will set default values which may not suit your display.
// The display controller data sheet will specify the minimum write cycle period. The
// controllers often work reliably for shorter periods, however if the period is too short
// the display may not initialise or graphics will become corrupted.
// PIO write cycle frequency = (CPU clock/(4 * RP2040_PIO_CLK_DIV))
//#define RP2040_PIO_CLK_DIV 1 // 32ns write cycle at 125MHz CPU clock

// For the RP2040 processor define the SPI port channel used (default 0 if undefined)

// For the STM32 processor define the SPI port channel used (default 1 if undefined)
//#define TFT_SPI_PORT 2 // Set to 1 for SPI port 1, or 2 for SPI port 2

// Define the SPI clock frequency, this affects the graphics rendering speed. Too
// fast and the TFT driver will not keep up and display corruption appears.
// With an ILI9341 display 40MHz works OK, 80MHz sometimes fails
// With a ST7735 display more than 27MHz may not work (spurious pixels and lines)
// With an ILI9163 display 27 MHz works OK.

// The ESP32 has 2 free SPI ports i.e. VSPI and HSPI, the VSPI is the default.

// Comment out the following #define if "SPI Transactions" do not need to be
// supported. When commented out the code size will be smaller and sketches will

// Transaction support is needed to work with SD library but not needed with TFT_SdFat
// Transaction support is required if other SPI devices are connected.

// Transactions are automatically enabled by the library for an ESP32 (to use HAL mutex)
// so changing it here has no effect

Things to try:

  1. Visually check the baklight LEDs are on. The BL signal may need to be biased to turn it on.
  2. The board is fitted with a level translator which may limit the maximum clock rate, so drop the SPI clock speed. Try 4MHz and increase if that works
  3. Use and configure a GPIO for the RST pin (the board may not be getting a reset at the right time if it is not connected or tied to the CPU reset)

Hi @Bodmer , i have identified another issue. I have defined different pins in setup file as below.
// ###### EDIT THE PIN NUMBERS IN THE LINES FOLLOWING TO SUIT YOUR ESP32 SETUP ######


// For ESP32 Dev board (only tested with ILI9341 display)
// The hardware SPI can be mapped to any pins

// #define TFT_MISO 19
#define TFT_MOSI 4
#define TFT_SCLK 5
#define TFT_CS 1 // Chip select control pin
#define TFT_DC 2 // Data Command control pin
#define TFT_RST 15 // Reset pin (could connect to RST pin)
// #define TFT_RST -1 // Set TFT_RST to -1 if display RESET is connected to ESP32 board RST

but when i upload Read_User_Setup.ino and open serial monitor, i see it as below

[code]
TFT_eSPI ver = 2.5.34
Processor = ESP32
Frequency = 240MHz
Transactions = Yes
Interface = SPI
Display driver = 7789
Display width = 240
Display height = 280

R0 y offset = 20
MOSI = GPIO 4
SCK = GPIO 5
TFT_DC = GPIO 5

Font GLCD loaded
Font 2 loaded
Font 4 loaded
Font 6 loaded
Font 7 loaded
Font 8 loaded
Smooth font enabled

Display SPI frequency = 40.00

It looks like you have more than 1 setup file being called up and that is also defining pins. Check you User_Setup_Select.h file and make sure only one setup file is being loaded.
