This is regarding the 7" display for Raspberry Pi. Kinda not really cool that you get to brand everything I make using your component.

I am planning to use ELECROW ESP32 display 7.0 Inch HMI Display 800×480 RGB TFT LCD Touch Screen Compatible with Arduino/LVGL/PlatformIO/ Micropython Without Acrylic Case. But I didn't get any info related to the brightness of the display.
Can you tell the brightness of the display and also suggest some display in 7.0 Inch HDMI with 600+nits brightness if possible.

Problem running demo program

NYBRU — Mon, 06 Jan 2025 13:15:55 +0000

Hi,
I am currently using a CrowPanel 3.5 capacitive RGB display and downloaded the demo code LVGL_RGB.
I have the same problem with the demo code of CrowPanel_Terminal_3.5inch_RGB_Capacitive.
I followed all the steps for setup the library with official documentation : https://docs.lvgl.io/master/details/integration/framework/arduino.html
I am using Arduino IDE and all libraries are installed and I double checked the paths.
Board is programming without errors, but nothing is displayed on the screen, and in the serial monitor I got this :
ESP-ROM:esp32s3-20210327
Build:Mar 27 2021
rst:0x8 (TG1WDT_SYS_RST),boot:0xb (SPI_FAST_FLASH_BOOT)
Saved PC:0x40378d8c
SPIWP:0xee
mode:DIO, clock div:1
load:0x3fce3808,len:0x44c
load:0x403c9700,len:0xbe4
load:0x403cc700,len:0x2a68
entry 0x403c98d4
Hello Arduino! V8.3.3
I am LVGL_Arduino

So we can see it display the manufacturing datas and the two last lines are in the setup function. But it happens every second and seems like it is reseting continually.
I dont really know where to start my researches since there is no compilation error.

Thank you for considering my problem.

ESP32 7" and OTA

yvesp123 — Thu, 04 Jan 2024 16:38:25 +0000

Hi,

I recently bought this: https://www.elecrow.com/esp32-display-7-inch-hmi-display-rgb-tft-lcd-touch-screen-support-lvgl.html and I'm having a great time with it. But I would like to be able to update my Arduino sketch over the air (OTA) with ArduinoOTA. I've added the few lines of code I usually use with my other boards to enable OTA and I can see the port in the Arduino IDE, but when I try to upload the sketch, the displays reboot and the upload fails. I assumed that it was due to the "Huge APP(3MB No OTA/1MB SPIFFS)" setting, and I tried one other setting that did not have "No OTA" but the display did not work anymore (blank), so I put "Huge APP(3MB No OTA/1MB SPIFFS)" back and was able to revive the display. Before I destroy something, I wanted to know if there is a way to make OTA work with this display? What setting should I change?

Thanks,

Connecting multipe E-Paper panel to 1 MCU

sachli — Mon, 21 Oct 2024 01:25:20 +0000

Hi, I want to ask is it possible if I use several (5 to 10) of this panel and connect to 1 ESP32?
Using this module is overkill and the price is too much to be used as price tag in supermarket.

From what I read from this datasheet, connection from panel to MCU just an SPI. So theoretically, it is possible to connect several e-paper panel through cable to 1 ESP.
I need your advice.
