ILI9488 working with arduinoIDE but not working with espIDF

[paxo-project]

Environment ( 実行環境 )

• MCU or Board name: ESP32 WROVER B
• Panel Driver IC: ILI9488
• Bus type: SPI (3 wires)
• LovyanGFX version: latest
• FrameWork version: ESP-IDF
• Build Environment: PlatformIO
• Operating System: Linux

Problem Description ( 問題の内容 )

Hello, using the same configuration code on the same assembly, I cannot connect the screen via espIDF (but this same configuration works perfectly under arduinoIDE). The problem is that we are using espIDF in our project

Expected Behavior ( 期待される動作 )

White screen

Steps to reproduce ( 再現のための前提条件 )

Just run a simple code to show color on the screen;

Code to reproduce this issue ( 再現させるためのコード )

Working on ArduinoIDE

Not working on espIDF

This code is run on a pcb made for the project paxo.

Thank you in advance!

hi,

please prodive esp-idf version, the content of sdkconfig or anything overloading its values may be helpful too

[paxo-project]

Thank you for your reply, I will give you all you need but I'm a beginner with espIDF, so I don't know the useful information, so can you tell me what do you need? (I will send you all when I would be available)

[paxo-project]

here is my .ini:

platform = espressif32
board = esp32dev
framework = espidf
monitor_speed = 115200
lib_deps =
    lovyan03/LovyanGFX@^1.1.9
build_flags =
    -DPLATFORM_ESP32DEV
    -DCONFIG_FATFS_MAX_LFN=255
    -I include
    -fexceptions

sdkconfig

LovyanGFX version: LovyanGFX@^1.1.9
pio version: PlatformIO 6.1.13 is currently the newest version available.
espIDF version: 6.4.0

If you need more information, ask me or follow the repository link?

Thank you in advance!

esp-idf version is written at the top of your sdkconfig file e.g. a commit shows you recently switched from 5.1.1 to 5.1.2

I couldn't compile your project (some unrelated errors) so I created a simple example from it:

• deleted everything except the files visible in the screenshot:

• copied this main.cpp in the src folder
• pio run -e esp32dev

please confirm the problem is still present when using this minimal example, and provide the full console output of the startup sequence

Strange, apart from this deprecation warning I don't see anything hinting at a driver or bus problem 🤔

Although it is recommended to use framework = arduino, espidf (esp-idf with Arduino as a component), I just tried both with a M5CoreS3 and it appears to work in both situations.

So here's the other recipe you can test, with Arduino as a component:

• use framework = arduino, espidf instead of framework = espidf in the platformio.ini
• copy the contents of this file in main.cpp (it's the Arduino version you linked earlier)
• uncomment/set/edit the following values in the sdkconfig file:

CONFIG_AUTOSTART_ARDUINO=y
# CONFIG_WS2812_LED_ENABLE is not set
CONFIG_FREERTOS_HZ=1000
CONFIG_MBEDTLS_PSK_MODES=y
CONFIG_MBEDTLS_KEY_EXCHANGE_PSK=y

Ok, thank you very much, I completely changed to arduino on pio because idf has a lot of problems. Now everything works perfectly
