Waveshare ESP32-S3-Touch-LCD-4 - Unable to use touch and I2C sensor at the same time #147

Currently testing a prototype built from the Squareline Porting example. This board uses the GT911 Touch controller which uses the same channel as any other I2C external device. I'm using a SEN66 sensor, using its library which requires the use of the Wire library. When I do this, panel->init() will fail and show something like this:

E (1506) i2c: i2c driver install error
Guru Meditation Error: Core 1 panic'ed (LoadProhibited). Exception was unhandled.

And then get stuck in a loop doing the same.

I'm using version 0.1.8 per the Waveshare instructions. I'm using an ESP IOExpander library, v0.0.4, altered by Waveshare, so updating any of this libraries breaks the code. I'm also using lv_conf.h by Waveshare. Being a dev board the connections can't be altered.

Would like to know if there's a way to not have the I2C error and if, maybe, making the updated library (0.2.2 as of posting) work be worth it.

Note: the LCD-4 and LCD-4.3 are not the same! For LCD-4, the custom board configurations are used.

Hi @dinisfc,

  1. For the conflict between this library and the Wire library on I2C, here's a solution: set ESP_PANEL_TOUCH_BUS_SKIP_INIT_HOST to 1 in ESP_Panel_Board_Custom.h. This way, the driver will not initialize the I2C host internally. You will then need to manually initialize the I2C host using Wire in your .ino file before initializing the panel.
  2. Since the Release v1.0.0 is in progress, I think it's better to update your project after it's ready.
  3. BTW, we can support the ESP32-S3-Touch-LCD-4 board in the library if it's helpful for you.

Thanks for the answer.
Setting ESP_PANEL_TOUCH_BUS_SKIP_INIT_HOST to 1 and having Wire.begin before anything else worked.

I've since updated to 0.2.2 and I'm now having errors again, even with ESP_PANEL_TOUCH_BUS_SKIP_INIT_HOST at 1.
I'm getting:

E (5056) i2c: i2c driver install error
E (5057) ESP_PanelHost: [ESP_FAIL] begin(153): I2C[0] install driver failed
E (5057) ESP_Panel: init(470): Initialize host failed
E (5061) ESP_Panel: begin(489): Panel is not initialized

Wire.begin and the sensor's reading start function are both before the screen. Running only the sensor or screen does not cause this error. While the system enters a loop showing this error repeatedly, the sensor remains on and running.

Hi @dinisfc,

Could you share the whole ESP_Panel_Board_Custom.h file? If the board uses an IO expander, which requires the use of the I2C bus, the ESP_PANEL_EXPANDER_SKIP_INIT_HOST should be disabled too.

Changing ESP_PANEL_EXPANDER_SKIP_INIT_HOST to 0 fixed it. Thanks.

I was wondering when we could use the ESP32-S3-Touch-LCD-4 board in the library. It will be helpful for the waveshare ESP32-S3-Touch-LCD-4 user without complex additional configuration.

Hi @Y1hsiaochunnn, could you help us add support for ESP32-S3-Touch-LCD-4 in the library?
