I'm relatively new to ESP32 and Arduino IDE, but not to microcontrollers in general. Have been using them professionally for decades, so I'm not completely stupid (or maybe I am). I've bought another ESP32 board, it's one of these: https://www.aliexpress.com/item/1005008214872438.html?spm=a2g0o.order_list.order_list_main.5.6e9e1802aB0za7 I have the software pack from Guition and I can thankfully reprogram the board with the default firmware - and it works nicely. What I can't do is rebuild the demo sketches. There are always various errors. I've gone through the getting started guide multiple times, trying various things. What I'd really, really like is a simple sketch that initialises the display and just draws a few blobs/text whatever. Everything I keep trying following examples that I've Googled simply does not work. It's a 4.0inch TFT with a 16-bit RGB interface. Oh, the touch panel works ok - I can create sketches that use that, and I can toggle the backlight on/off - so my pinouts must be good. Frustration level = high. Sadly, experience level = low.

Welcome to the forum Post one of the demo sketches that you have problems with, using code tags when you do. Post the full error message copied from the IDE using the button provided and post that here too, again using code tags

Thanks for the reply. I didn't get an email notification that there was a reply here, so sorry for the delay. Hope these code tags have worked. I have the sketch on D: and ArduinoIDE is on C: (together with libraries). Hope they don't need to be in specific places. The sketch is from a datapack that Guition supply (after you hunt it down). They have a getting started guide, but you need to install a load more libraries that those they suggest. /******************************************************************************* * LVGL Widgets * This is a widgets demo for LVGL - Light and Versatile Graphics Library * import from: https://github.com/lvgl/lv_demos.git * * Dependent libraries: * LVGL: https://github.com/lvgl/lvgl.git * Touch libraries: * FT6X36: https://github.com/strange-v/FT6X36.git * GT911: https://github.com/TAMCTec/gt911-arduino.git * XPT2046: https://github.com/PaulStoffregen/XPT2046_Touchscreen.git * * LVGL Configuration file: * Copy your_arduino_path/libraries/lvgl/lv_conf_template.h * to your_arduino_path/libraries/lv_conf.h * Then find and set: * #define LV_COLOR_DEPTH 16 * #define LV_TICK_CUSTOM 1 * * For SPI display set color swap can be faster, parallel screen don't set! * #define LV_COLOR_16_SWAP 1 * * Optional: Show CPU usage and FPS count * #define LV_USE_PERF_MONITOR 1 ******************************************************************************/ #include "lv_demo_widgets.h" /******************************************************************************* * Start of Arduino_GFX setting * * Arduino_GFX try to find the settings depends on selected board in Arduino IDE * Or you can define the display dev kit not in the board list * Defalult pin list for non display dev kit: * Arduino Nano, Micro and more: CS: 9, DC: 8, RST: 7, BL: 6, SCK: 13, MOSI: 11, MISO: 12 * ESP32 various dev board : CS: 5, DC: 27, RST: 33, BL: 22, SCK: 18, MOSI: 23, MISO: nil * ESP32-C3 various dev board : CS: 7, DC: 2, RST: 1, BL: 3, SCK: 4, MOSI: 6, MISO: nil * ESP32-S2 various dev board : CS: 34, DC: 35, RST: 33, BL: 21, SCK: 36, MOSI: 35, MISO: nil * ESP32-S3 various dev board : CS: 40, DC: 41, RST: 42, BL: 48, SCK: 36, MOSI: 35, MISO: nil * ESP8266 various dev board : CS: 15, DC: 4, RST: 2, BL: 5, SCK: 14, MOSI: 13, MISO: 12 * Raspberry Pi Pico dev board : CS: 17, DC: 27, RST: 26, BL: 28, SCK: 18, MOSI: 19, MISO: 16 * RTL8720 BW16 old patch core : CS: 18, DC: 17, RST: 2, BL: 23, SCK: 19, MOSI: 21, MISO: 20 * RTL8720_BW16 Official core : CS: 9, DC: 8, RST: 6, BL: 3, SCK: 10, MOSI: 12, MISO: 11 * RTL8722 dev board : CS: 18, DC: 17, RST: 22, BL: 23, SCK: 13, MOSI: 11, MISO: 12 * RTL8722_mini dev board : CS: 12, DC: 14, RST: 15, BL: 13, SCK: 11, MOSI: 9, MISO: 10 * Seeeduino XIAO dev board : CS: 3, DC: 2, RST: 1, BL: 0, SCK: 8, MOSI: 10, MISO: 9 * Teensy 4.1 dev board : CS: 39, DC: 41, RST: 40, BL: 22, SCK: 13, MOSI: 11, MISO: 12 ******************************************************************************/ #include #define GFX_BL 38 Arduino_ESP32RGBPanel *bus = new Arduino_ESP32RGBPanel( 39 /* CS */, 48 /* SCK */, 47 /* SDA */, 18 /* DE */, 17 /* VSYNC */, 16 /* HSYNC */, 21 /* PCLK */, 11 /* R0 */, 12 /* R1 */, 13 /* R2 */, 14 /* R3 */, 0 /* R4 */, 8 /* G0 */, 20 /* G1 */, 3 /* G2 */, 46 /* G3 */, 9 /* G4 */, 10 /* G5 */, 4 /* B0 */, 5 /* B1 */, 6 /* B2 */, 7 /* B3 */, 15 /* B4 */ );

Same thread as it's the same board. The module is very similar to Waveshare ESP32-S3-Touch-LCD-4 I have followed the sort-of getting started/tutorial, installing libraries etc, but even with the simplest of examples that they provide, I get compilation errors. /** * # Panel Test Example * * The example demonstrates how to develop built-in or custom development boards using the `ESP_Panel` driver and tests by displaying color bars and printing touch point coordinates. * * ## How to Use * * Follow the steps below to configure: * * 1. For **ESP32_Display_Panel**: * * - Follow the [steps](https://github.com/esp-arduino-libs/ESP32_Display_Panel/blob/master/docs/How_To_Use.md#configuring-drivers) to configure drivers if needed. * - If using a supported development board, follow the [steps](https://github.com/esp-arduino-libs/ESP32_Display_Panel/blob/master/docs/How_To_Use.md#using-supported-development-boards) to configure it. * - If using a custom board, follow the [steps](https://github.com/esp-arduino-libs/ESP32_Display_Panel/blob/master/docs/How_To_Use.md#using-custom-development-boards) to configure it. * * 2. Navigate to the `Tools` menu in the Arduino IDE to choose a ESP board and configure its parameters. For supported * boards, please refter to [Configuring Supported Development Boards](https://github.com/esp-arduino-libs/ESP32_Display_Panel/blob/master/docs/How_To_Use.md#configuring-supported-development-boards) * 3. Verify and upload the example to your ESP board. * * ## Serial Output * * ```bash * ... * Panel test example start * Initialize display panel * Turn off the backlight * Draw color bar from top to bottom, the order is B - G - R * Turn on the backlight * Panel test example end * Touch point(0): x 141, y 168, strength 47 * Touch point(1): x 165, y 288, strength 45 * Touch point(2): x 258, y 343, strength 33 * Touch point(3): x 371, y 317, strength 24 * ... * ``` * * ## Troubleshooting * * Please check the [FAQ](https://github.com/esp-arduino-libs/ESP32_Display_Panel/blob/master/docs/FAQ.md) first to see if the same question exists. If not, please create a [Github issue](https://github.com/esp-arduino-libs/ESP32_Display_Panel/issues).

Hi, I have the same board and can compile 2 of the samples, couldn’t get the music player to work but didn’t try very hard because I don’t need it. The first 3 examples in the list are complete, the others are only code snippets so won’t compile on their own. I’m not at my computer but some things that come to mind to check. You need to use lvgl v8.3, other versions will not work. You need to use a custom partition so there is enough space for the programs, one of the examples is 5.8MB. There is an example provided, don’t recall exactly where, copy this to the folder with the ino and rename to partitions.cvs You may need to clear the Arduino temporary files if you get errors saying it runs out of space. The issue I currently have is that the Wi-Fi does not work in the examples, it crashes when trying to scan for networks. Wi-Fi works ok in a dedicated sketch so hardware is ok. Would be interested to know if you have the same issue.

Hi, and thanks very much for your comments. I'm trying to compile starting with 1_2_4.0_LvglWidgets. But I'm having very strange compilation errors, like something basic is missing. I've changed lvgl to 8.3.0 (and installed many other libraries which were not requested to do so in the getting started doc). Here's the compiler log output (just from where the errors start - but there's lots more I cut out).

I'm going to need WiFi too (much later on I think), so I'll probably meet the same problems you're having.

Try exiting the IDE and deleting the temporary files. Some are here: c:\users\xxxx\appdata\local\temp There is also another folder which can be deleted for a cleanup but I don’t recall where this is.

Can you also paste a screenshot of your board settings in the IDE.

By board settings, you mean this...? [bs] I'll have a look at those temporary files too. Thanks.

Yes, board settings look ok. Tomorrow I will check what libraries I have installed. If I recall correctly ESP needs to be v2 not v3.

These are the libraries I have installed. [image] [image] [image]

Thanks for your help.

I have another forum topic that ends with a working solution.
