ESP32-S3-LCD-1.28 display not working

kevin134 · July 4, 2025, 10:32am

Hi!

I bought a development board with a built-in screen ESP32-S3-LCD-1.28 from this link https://www.aliexpress.us/item/1005006754030454.html?spm=a2g0o.order_list.order_list_main.20.3bf41c24AWBO9i&gatewayAdapt=4itemAdapt

I’m trying using PlatformIO display something on the screen but it doesn’t working. This is my code:

main.cpp

#include <Arduino.h>
#include <TFT_eSPI.h>

TFT_eSPI tft = TFT_eSPI();

void setup() {
  tft.init();
  tft.setRotation(1);
  tft.fillScreen(TFT_WHITE);
  tft.setTextFont(4);
}

void loop() {
  tft.fillScreen(TFT_WHITE);
  tft.fillRectHGradient(0, 0, 160, 50, TFT_MAGENTA, TFT_BLUE);
  tft.setCursor(10, 10);
  tft.print("test");

  delay(100);
}

platformio.ini

[env:esp32-s3-devkitc-1]
platform = espressif32
board = esp32-s3-devkitc-1
framework = arduino
board_build.arduino.memory_type = qio_opi
board_build.flash_mode = qio
board_build.psram_type = opi
board_upload.flash_size = 4MB
board_upload.maximum_size = 4194304
board_build.partitions = default.csv
board_build.extra_flags = 
	-DBOARD_HAS_PSRAM
lib_deps = bodmer/TFT_eSPI@^2.5.43

After run that i see only black screen. I learn this board from this https://www.youtube.com/watch?v=GosqWcScwC0

All of this seems wrong when the official reference says 16 MByte of QIO Flash and QSPI PSRAM. You’re setting it for 4MB QIO Flash and OPI PSRAM.

This should be

board_build.arduino.memory_type = qio_qspi
board_build.flash_mode = qio
board_build.psram_type = qspi
board_upload.flash_size = 16MB
board_build.partitions = default_16MB.csv

Where do you configure the TFT_eSPI library for your display? Just including the library is not enough. You have to setup all the defines or an include file for the display.

The official Wiki for the board (no touch version) at

https://www.waveshare.com/wiki/ESP32-S3-LCD-1.28#Install_library

provides a modified TFT_eSPI version at https://files.waveshare.com/wiki/ESP32-S3-LCD-1.28/ESP32-S3-LCD-1.28-Demo.zip which has the necessary library and files

So if you just want a very easy way to that premade library:

Delete the lib_deps expression from your platformio.ini
Delete the .pio folder of your project
Copy in the downloaded TFT_eSPI folder into lib/TFT_eSPI
Copy in the downloaded TFT_eSPI_Setups folder into lib/TFT_eSPI_Setups
Build again

kevin134 · July 4, 2025, 11:51am

Ok, thank you. I changed my platformio.ini file and i have this content:

[env:esp32-s3-devkitc-1]
platform = espressif32
board = esp32-s3-devkitc-1
framework = arduino
board_build.arduino.memory_type = qio_qspi
board_build.flash_mode = qio
board_build.psram_type = qspi
board_upload.flash_size = 16MB
board_build.partitions = default_16MB.csv
board_build.extra_flags = 
	-DBOARD_HAS_PSRAM

My main.cpp file:

#include <TFT_eSPI.h>
#include <SPI.h>

TFT_eSPI tft = TFT_eSPI();

void setup() {
  Serial.begin(115200);

  tft.init();
  tft.setRotation(1);
  tft.fillScreen(TFT_WHITE);
  tft.setTextFont(4);
}

void loop() {
  tft.fillScreen(TFT_WHITE);
  tft.fillRectHGradient(0, 0, 160, 50, TFT_MAGENTA, TFT_BLUE);
  tft.setCursor(10, 10);
  tft.print("test");
}

And my lib directory content:

I tried include #include <Setup207_GC9A01.h> or #include <Setup208_ST7789.h> file but still doesn’t working

maxgerhardt · July 4, 2025, 12:44pm

The Setup208_ST7789.h seems to be for ESP32-S3-Touch-LCD-1.69, not ESP32-S3-Touch-LCD-1.28 like the Setup207_GC9A01.h file says.

Does basic blinky and serial work at all? The chip might not be booting with wrong flash / psram configuration.

#include <Arduino.h>
#define LED 40 /* LCD backlight as LED.. */
void setup() {
  Serial.begin(115200);
  pinMode(LED, OUTPUT);
}

void loop() {
  digitalWrite(LED, LOW);
  delay(1000);
  digitalWrite(LED, HIGH);
  delay(1000);
  Serial.println("Blinky!");
}

with a platformio.iniof

[env:esp32-s3-devkitc-1]
platform = espressif32
board = esp32-s3-devkitc-1
framework = arduino
board_build.arduino.memory_type = qio_qspi
board_build.flash_mode = qio
board_build.psram_type = qspi
board_upload.flash_size = 16MB
board_build.partitions = default_16MB.csv
board_build.extra_flags = 
	-DBOARD_HAS_PSRAM
monitor_speed = 115200

kevin134 · July 4, 2025, 1:01pm

Full screen blink and I have Blinky! message in serial monitor

maxgerhardt · July 4, 2025, 1:07pm

Okay.

I just noticed a slew of redefinition warnings when I compile a test firmware.

Can you go into lib/TFT_eSPI/USer_Setup_select.h and comment out line 27? Then these warnings should go away.

Within the same platformio.ini as in the previous post, can you use this code

#include <Arduino.h>
#include <TFT_eSPI.h>

TFT_eSPI tft = TFT_eSPI();

#if defined(ILI9341_DRIVER)
#error "Wrong screen type defiend (ILI9341)"
#endif

#if defined(GC9A01_DRIVER)
#warning "Right screen type defiend"
#endif

void setup() {
  delay(2000); // give serial monitor time to startup
  Serial.begin(115200);
  Serial.println("Firmware start");
  tft.init();
  Serial.println("TFT init done");
  tft.setRotation(1);
  tft.fillScreen(TFT_WHITE);
  tft.setTextFont(4);
  Serial.println("Set done");
}

void loop() {
  Serial.println("loop");
  tft.fillScreen(TFT_WHITE);
  tft.fillRectHGradient(0, 0, 160, 50, TFT_MAGENTA, TFT_BLUE);
  tft.setCursor(10, 10);
  tft.print("test");

  delay(1000);
}

During build, hopefully this message should appear

src/main.cpp:11:2: warning: #warning "Right screen type defiend" [-Wcpp]
   11 | #warning "Right screen type defiend"
      |  ^~~~~~~

confirming the right screen type. What’s the seiral output?

Okay, so it’s crashing.

Please add the following to the platformio.ini:

build_type = debug
monitor_filters =
  esp32_exception_decoder

And press “upload and monitor” again. What’s the output?

Also, what is the platform and packages that PlatformIO uses? That’s printed at the beginning of the build output. For me, I’m on (pioarduino) platform 54.3.20 with Arduino-ESP 3.2.0

maxgerhardt · July 4, 2025, 1:33pm

This is wild. The Espressif macro for “give me the register base for SPI0” just returns a nullpointer (0x0), at i = 0.

#define REG_SPI_BASE(i)         (((i)>=2) ? (DR_REG_SPI2_BASE + (i-2) * 0x1000) : (0))    // GPSPI2 and GPSPI3

It’s crashing because it wants to write to 0x00000010.

I need a moment to look at this.

kevin134 · July 4, 2025, 1:36pm

I done this with commented 27 line in User_Setup_Select.h file

maxgerhardt · July 4, 2025, 1:39pm

This seems relevant:

ESP32 Core 1 panic'ed (StoreProhibited). Exception was unhandled when tft.init() is executed.

opened 02:45AM - 21 May 24 UTC

taylorjwnc20

The issue that I am encountering is that a "Guru Meditation Error: Core 1 panic…'ed (StoreProhibited). Exception was unhandled." just prior to executing the tft.init() function. This issue appears to be only graphics bases since I can execute this sketch with only Serial.println("..."); calls. I can use the Adafruit_GFX.h with the Adafruit_ST7789.h driver to do a test on a GFX application. During an update something changed and I am at a loss to determine the root cause. Wiring is correct ( I have checked it many times). 1. IDE - Arduino version 2.3.2 CLI version 0.35.3 2. TFT_eSPI - version 2.5.43 3. Board Version - esp32 version 3.0.0.rc3 (I have regressed it back to ESP version 2.0.16 with no change in functionality, still reboots). 4. PROCESSOR - ESP32-S3 5. TFT Driver - ST7789 (TFT_eSPI sourced) 6. TFT Interface - SPI See the following attached files for additional information you require: [User_Setup.zip](https://github.com/Bodmer/TFT_eSPI/files/15383585/User_Setup.zip) Sketch: [WIFI_Channel_List.zip](https://github.com/Bodmer/TFT_eSPI/files/15383589/WIFI_Channel_List.zip) TFT ; ST7789 IC 1.9 Inch ips Full View TFT Display LCD Color Module SPI Serial Port HD 170x320 MSP430 and C51 Programs I have only one of these displays.... ![1_9inch ST7789 TFT](https://github.com/Bodmer/TFT_eSPI/assets/67809491/9d0ee67d-4482-447a-849c-f635c43043d9) DEBUG Output: [Debug Output.zip](https://github.com/Bodmer/TFT_eSPI/files/15383726/Debug.Output.zip) Plus further information as appropriate to the problem: 1.

At the base, some TFT_eSPI or Espressif code is wrong. I think https://github.com/Bodmer/TFT_eSPI/issues/3329#issuecomment-2808875061 is close to a good explanation.

Arduino cores before 2.0.16 did not define REG_SPI_BASE, so TFT_eSPI defines it in this case to always DR_REG_SPI2_BASE as a bugfix. Arduino cores after 2.0.16 do define it to

#define REG_SPI_BASE(i)         (((i)>=2) ? (DR_REG_SPI2_BASE + (i-2) * 0x1000) : (0))

which, together with the definition of what’s used for i is FSPI and

#define FSPI 0

gives a null pointer (0) instead of DR_REG_SPI2_BASE. This crashes execution.

So it seems like the definition of FSPI is wrong for ESP32S3 or TFT_eSPI should be using HSPI not FSPI as the SPI_PORT.

We ““fixed”” it by downgrading the platform in the platformio.ini to use an older Arduino core, where TFT_eSPI uses the right REG_SPI_BASE value.

Other ports suggest that it should also work on the newer Arduino cores and ESP32S3 if you define the USE_HSPI_PORT macro to make that happen.

So, if you want another test:

[env:esp32-s3-devkitc-1]
; uses Arduino-ESP32 2.0.17
platform = espressif32@6.11.0
board = esp32-s3-devkitc-1

board_build.flash_mode = qio
board_build.psram_type = qspi

; PSRAM + bugfix against TFT_eSPI/issues/3329 on newer Arduino cores
board_build.extra_flags = 
   -DBOARD_HAS_PSRAM
   -DUSE_HSPI_PORT
monitor_speed = 115200

build_type = debug
monitor_filters =
  esp32_exception_decoder

jason2866 · July 5, 2025, 3:15pm

Long story short the REG_SPI_BASE in IDF is wrong. Submitted a PR and espressif IDF messed the PR up by changing it. In my private fork i have corrected. To make the Bodmer TFT_eSPI (which is outdated BTW.) you have to manually override which SPI is used
