DIE07300S : CrowPanel ESP32 4.2” E-paper HMI Display - Elecrow Wiki

nerdingOut — Thu, 20 Mar 2025 04:16:47 +0000

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.

What I’ve Tried So Far:
• Used the waveshare_epaper component in ESPHome, which supports SSD1680 (a similar driver).
• Tried different models (4.20in-bv2, 4.20in-bv2-bwr) in ESPHome.
• Adjusted reset durations and power cycled the display.
• Verified SPI pin connections match the CrowPanel documentation.
• 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.

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

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

esphome config code for CrowPanel ESP32 E-Paper HMI Displays

Any esphome config for these ePaper displays?
I am kind of stuck without here:

But this file is not for the E-Paper displays!

DIE01021S : CrowPanel ESP32 2.13” E-paper HMI Display - Full screen refresh

malachib — Sat, 15 Feb 2025 16:05:48 +0000

Hello.
Is it possible to do a refresh in which the entire screen does NOT flash?
There seem to be two definitions of "partial refresh":
1. Indicate only certain frame buffer areas to change on screen
2. Physically see only particular regions activate/deactivate
I am familiar with the procedure for #1. My question pertains to #2.
At the moment, no matter what I do with LUT tables, the entire screen flashes 2 or 3 times when a refresh is requested. To rephrase the beginning sentence, I would like to refresh the display in such a way where those flashes do not occur. Is this possible?

DIS08792E : CrowPanel ESP32 5.79” E-paper HMI Display - What's the Power Consumption?

lockandtour — Tue, 04 Feb 2025 16:37:08 +0000

Anyone have any insight as to the power consumption of the 5.79" use cases below? I am trying to understand how big of a battery would be needed to have my device load an image once a day and then go into deepsleep.

Power to initialize, clear, and display a new image (if there is any optimized power use code you have for this I would appreciate it).
Power used for the device after the esp_deep_sleep_start() if run and remains in a deep sleep.
Normal use while running the code to initialize and then update the image.

DIS08792E : CrowPanel ESP32 5.79” E-paper HMI Display - Tutorials / Examples?

I just received my CrowPanel ESP32 5.79” E-paper HMI Display (SKU DIS08792E001).

Is there any example code out there for this product? Any tutorials?

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.)

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.)

Thanks, and happy hacking.
