        <description><![CDATA[<p>I have the CrowPanel ESP32 HMI 7.0-inch Display. I would like to have the screen communicate with an ESP32-S3 via UART; the ESP32-S3 needs to be able to communicate with the display and vice versa. does someone know how to do this, I tried to communicate with an arduino uno and it works fine, once i try it to communicate with an esp32 it just doesn't work. can someone give me extra information or a sample code? thank you</p>

I'm going through the "Get Started with ESP32:" YouTube tutorial.</p>

<p>I'm using the ESP32 Display -7 inch, SKU: DIS08070H, and I have this problem both when I manually (boot + reset) put the panel into upload state and with the default demo running. My upload fails with:<br />

        <description><![CDATA[<p>Any tips on using extra GPIO pins on this otherwise very neat device?<br />
There's two gpio pins (IO4, IO12) available on the FPC connector, but without a suitable breakout cable i cannot use them. I've read some references about test io pads for the same pins somewhere on the pcb but i can't find any marks. Maybe soldering a wire directly to the FPC connector is the best approach? I only need one gpio pin for my project...</p>

        <description><![CDATA[<p>Hello, I just got my Elecrow 7.0 inch ESP32 display and it did not pop up in the ports in my arduino ide.<br />
So I checked device manager on windows and noticed it under "Other Devices" saying it did not find any drivers for it.</p>

<p>Does anyone know what drivers it requires? I tried to search through the PDF they had on their website searching for "USB" and did not see any mentions of drivers.</p>

        <description><![CDATA[<p>I recently purchased the CrowPanel ESP32 4.2-inch E-Paper Display, which uses the SSD1683 driver IC. I’m trying to integrate it with ESPHome but have been running into issues.</p>

<p>What I’ve Tried So Far:<br />
    •   Used the waveshare_epaper component in ESPHome, which supports SSD1680 (a similar driver).<br />
    •   Tried different models (4.20in-bv2, 4.20in-bv2-bwr) in ESPHome.<br />
    •   Adjusted reset durations and power cycled the display.<br />
    •   Verified SPI pin connections match the CrowPanel documentation.<br />
    •   Checked logs—ESPHome recognizes the display, but operations are very slow (Component display took a long time for an operation (157ms)) and no image updates.</p>

<p>Questions:<br />
    1.  Has anyone successfully integrated this CrowPanel SSD1683 e-paper display with ESPHome?<br />
    2.  If so, which settings or custom drivers did you use?<br />
    3.  Would a custom ESPHome driver be needed for SSD1683, or is there an alternative workaround?<br />
    4.  Has anyone tried controlling this panel with the GxEPD2 Arduino library instead?</p>

<p>Any guidance, YAML examples, or alternative approaches would be greatly appreciated. Thanks in advance!</p>

        <description><![CDATA[<p>Does anyone anywhere have an example of Squareline / LVGL working under ESP-IDF (NOT Arduino) for the Crowpanel 5" display? (Or any ESP32-S3 Elecrow display?). All the examples keep using Arduino which won't work for production delivery.  Any help is appreciated.. Elecrow's links do not have anything that actually compiles or functions under ESP-IDF (VS Code or PlatformIO).</p>

        <description><![CDATA[<p>I just received my CrowPanel ESP32 5.79” E-paper HMI Display (SKU <a rel="nofollow" href="https://www.elecrow.com/crowpanel-esp32-5-79-e-paper-hmi-display-with-272-792-resolution-black-white-color-driven-by-spi-interface.html" title="DIS08792E001">DIS08792E001</a>).</p>

<p>Is there any example code out there for this product? Any tutorials?</p>

<p>I've looked at the schematic and data sheets linked from the product page, and while these are greatly helpful, they don't really give me all the information I need to write code for this thing. (In particular, I know nothing about the actual e-paper display, how the SSD1683 controllers are hooked up to it, or the appropriate register settings to make the latter talk to the former.)</p>

<p>Is there source available for the demo app that ships with the device? Any Arduino libraries? (I know how to set up the Arduino IDE for the "ESP32S3 Dev Module" board config; I'm looking for the display and display controller specifically in terms of library supporrt.)</p>

<p>Thanks, and happy hacking.</p>
