Re: ESP32-S3 Continuous Touch Slider Data

I realized I had used the wrong constant for the event subscription. When subscribing to TOUCH_SLIDER_EVT_ON_CALCULATION I get continuous updates during sliding operations.

ESP32-S3 Continuous Touch Slider Data

Hi, I'm using the touch slider API from IDF v5.1 with an ESP32-S3 and I'd like to get a continuous slide position update while the user is sliding the finger over the touch slide. Using touch_slider_subscribe_event I get a callback when the slide is touched and released, but the callback is not call...

ESP32S3 touch screen library

Is there any library or example on how to use a 4-pin capacitive touch display on an ESP32S3? I see examples in https://github.com/espressif/esp-idf/tree/master/examples/peripherals/touch_sensor/touch_element but they are labeled as ESP32S2 only. I managed to run the touch_matrix example (https://gi...

Awesome, thanks!
Lowering pclk_hz from 10M to 5M solved it!

Display artifacts on ESP32-S3 & ILI9341 LCD (Intel 8080 bus) with lvgl

I have hooked up an ILI9341 to an ESP32S3 using the Intel 8080 interface, following the example at https://github.com/espressif/esp-idf/tree/master/examples/peripherals/lcd/lvgl When the screen animation is running, I see some artifacts occasionally. When I additionally initialize an i2s interface (...

Found it:

Code: Select all

esp_lcd_panel_mirror(panel_handle, true, true);
esp_lcd_panel_swap_xy(panel_handle, true);

One follow-up issue is that the display is mirrored. I haven't found any config setting yet that would flip it.

That was it! Connected RD to 3.3V and it worked. Such an easy fix!
Thank you so much!

ESP32-S3 & ILI9341 LCD lvgl example using the Intel 8080 (parallel) interface

Hello, I'm trying to get the lvgl example (https://github.com/espressif/esp-idf/tree/release/v4.4/examples/peripherals/lcd/lvgl) working using an ESP32-S3 with an ILI9341 display. I changed the code to reflect my wiring and the display spec: //////////////////////////////////////////////////////////...
