Good Day Guys when loading the Squareline porting example on the new update I am experiencing the following error not sure why and there's no Library for it?

`c:\Users\esp\Desktop\sqaure2\libraries\ESP32_Display_Panel\src\lcd\ESP_PanelLcd.cpp:13:10: fatal error: esp_memory_utils.h: No such file or directory

Hi @ReacherS3, the version of arduino-esp32 should be v3.0.0-alpha3 as shown in README.

Hi @ReacherS3, the version of arduino-esp32 should be v3.0.0-alpha3 as shown in README.

Thanks @Lzw655 I have no idea how to get that running.

[Lzw655]

@ReacherS3 It's a development release. You can follow the docs to install it. BTW, should use https://espressif.github.io/arduino-esp32/package_esp32_dev_index.json url.

[ReacherS3]

@Lzw655 Thank you the mistake was on my side I never entered the index URL that's why it never registered in the IDE under ESP32 to update to v3 thank for the assistance and always being available to assist you are the best!!

I will upload the files that I promised as soon as I can get them to fit on Github

[Lzw655]

Yeah, also thank you for using this library. 😉

[ReacherS3]

The previous version supported the CH422G Io expansion chip the new release does not contain the expansion chip files so as soon as I enable #define ESP_PANEL_USE_TOUCH (0) // 0/1 it interferes with the display is there a way to fix this?

I believe if I cant enable the touch I will not be able to use #define ESP_PANEL_USE_EXPANDER (0) // 0/1 as well?

[ReacherS3]

If I update accordingly I get the following errors!

Hi @ReacherS3, the ESP32_IO_Expander library didn't support CH422G. Are you using a third-party one? If so, can you provide it to me? Then I can add CH422G into the ESP32_IO_Expander.

[Lzw655]

Oh, I realize the reason for your issues, please check the below points:

1. For the touch, set ESP_PANEL_TOUCH_I2C_ADDRESS correctly.
2. For the IO expander, set ESP_PANEL_EXPANDER_I2C_ADDRESS correctly. Since some expanders can be assigned various I2C addresses, users should adjust ESP_PANEL_EXPANDER_I2C_ADDRESS based on the actual circumstances.

Hi @Lzw655

Above is the board that I am using it's definately using CH422G as the previous version of Display panel and IO expander supported CH422G CHIP.

https://files.waveshare.com/wiki/ESP32-S3-Touch-LCD-4.3/S3-4.3-libraries.zip

This link will download the required files that I used before including the CH422G Chip files

Thanks @Lzw655

[ReacherS3]

I use the CH422G for CAN bus communication, Backlight, SD Card etc.

Hi @ReacherS3, sorry for the late. I have been very busy these days.

Thanks to the contribution of @lboue, we can use CH422G in the PR now. Can you try it again?

Thanks @Lzw655 This CH422G test file is working with arduino-esp3 3.0.0-alpha3 release: CH422G_Test_3.0.0-alpha3.ino

[ReacherS3]

Thanks to the both of you and the effort and contributions you are awesome guys I am busy myself these days no need to apologize.

I will load up everything once I get back to that part of the project integrating temperature sensors now and GPS tracking capabilities once that's complete I will revert back to the updated library. @lboue @Lzw655

Once again thank you so much for all the support on this library!!

[lboue]

@ReacherS3 Can you try last released versions?

• library ESP32_Display_Panel at version 0.1.1
• library ESP32_IO_Expander at version 0.0.3

[ReacherS3]

Thanks @lboue

Just a quick question I have managed to load all the updated files and managed to get the display running without any errors at all which is pretty good considering I always had the LCD errors they are fixed now.

My concern now is once I start the device and leave it running for about an hour or more the screen starts drifting very slowly to the side or bottom completely throwing out my loaded screen and duplicate display across one screen and everything stops functioning a reset fixes the issue but this will cause issues once installed everywhere in mass production units.

@Lzw655

[Lzw655]

Hi @ReacherS3, could you take a video to show me the issue? I think it's the screen drift issue of RGB LCD. Did you try the solution here?

[lboue]

@ReacherS3 Perhaps a new thread should be opened for this drift issue?
