Troubles migrating from ESP32-S3-LCD-EV-Board v1.4 to ESP32-S3-LCD-EV-Board v1.5

[romaincgs]

Hello,

I'm trying to solve some issues with embedded software. The code has been flashed on an ESP32-S3-LCD-EV-Board v1.4, and it worked well: everything was displayed fine. Now, I don't have any ESP32-S3-LCD-EV-Board v1.4 and need to use an ESP32-S3-LCD-EV-Board v1.5. I have been trying to solve the issue for some time now and can't figure it out, which is why I am reaching out to this forum. I am not used to forums, so please excuse me if I don't provide everything you need to help me.

I've tried flashing this example: https://github.com/espressif/esp-dev-ki ... mart_panel on my board, and it works fine. I've been recording the logs sent by the ESP while booting. Here are the parts of the logs concerning the display with both software:

Tell me if I can provide anything else that could help you help me!

I found the problem : when upgrading from lcd V1.4 to V1.5, 4 pins have been swapped but the librairy (espressif__esp32_s3_lcd_ev_board v2.1.0) was changing only two of them.
The issue have been reported.
If I'm not wrong and we need to wait for Espressif to update the library, here's what must be changed :
In the file bsp_sub_board.c you need to add

Code: [Select all] [Expand/Collapse]

1.             io_config.line_config.scl_expander_pin = BSP_I2C_SCL_R16;
2.             io_config.line_config.sda_expander_pin = BSP_I2C_SDA_R16;
