Product: Elecrow 7-inch HDMI Touchscreen Monitor (RC070P) SKU: DPM50080D
Question:
I tried to connect the Elecrow 7-inch HDMI Touchscreen Monitor (RC070P) to my Raspberry Pi 5 and got "no signal." I tried following the manual and modified "config.txt" as it was suggested, but I had no luck.
The monitor itself is functioning - had no issues with Raspi Zero, and Xwindows on my Raspi 5 is also functioning- I'm able to plug/connect it to my big monitor.
Is the manual up to date for Raspi 5?
Answer:
Could you please try directly flashing the corresponding system from the following link?
And There is no need to modify the “config.txt” file after flashing.

I need to use one or more PCF8575s with my HMI displays (7, 5, and 2.8 inches) but I cannot get my PCF8575 IO Expander Module I2C to 16IO to work for the life of me. I read all 8575 related posts here but none of the methods has worked for me. First, what library do you recommend, second, is there sample code I can look at for that library?

Product: 7-Inch HDMI Touchscreen Display SKU: DIS08070H
Question:
I hope this message finds you well. I recently purchased your 7-Inch HDMI Touchscreen Display, and I’m really enjoying using it. I plan to keep the device plugged in and running for extended periods (possibly continuously), and I wanted to ask about any safety considerations related to that.
Could you please let me know:
-Is it safe to keep the device plugged in and powered on for long periods of time?
-Are there any risks of overheating or other safety hazards I should be aware of?
-Does the device have any built-in protections (e.g., thermal shutdown, overcurrent protection) to ensure safe long-term operation?
Answer:
Please make sure that the power supply is 5V — connecting anything higher than 5V may damage the product.
As for long-term use, no worries — the product has been tested.

Product: CrowPanel 7.0" -HMI ESP32 Display SKU: DIS08070H
Question:
Hi I posted this question on the forum, please help me: Elecrow, please help. I recently updated Arduino IDE and all of the libraries and board files and found that afterwards the 7" LCD crowpanel would not load any of the graphics, the screen was always blank. All the programs uploaded without error and programs not using the LCD work fine. Starting with Lesson 2 from the tutorial nothing was working anymore. All had worked before the update. I found this thread and I rolled back the lovyanGFX library, the ESP32 board file and Arduino IDE to the versions listed and everything worked again. https://forum.elecrow.com/discussion/585/esp32-hmi-demo-code-updated-compatible-with-new-version-of-esp32-package/p1 Rolling back to: Arduino IDE 2.2.1 (or 1.8.19) LovyanGFX 1.1.12 I want to use the latest version of everything, what do I need to do to get it to work. I'd prefer not to be running all old versions of these files.
Answer:
Really sorry about this, but if you're using different libraries or ESP32 board, you’ll need to do some custom adaptation yourself to make things work. However, the version of the Arduino IDE won’t affect the code— you’re free to use the latest version.

Question:
May I ask you another question? I have everything running with your C++ code, works perfectly.
Do you also have an example integration for the Crowpanel e-Ink Display for ESPHome, so that I can run it from Home Assistant? This would be so cool!

We haven't released the ESPhome version of the driver yet. Please stay tuned for updates on our website.
