CrowView Note - Battery died!

lyx — Sat, 25 Jan 2025 01:09:02 +0000

I received my CrowView Note in November 2024 and it was working fine then. Battery was able to last at least a few (2-3) hours. When turning on the device after a month or so, battery is empty so the device is charged. But after a long time (3-4 hours), the device can only turn on for about 10 seconds before turning off. When checking the charging indicator above INSERT key, it turns off after a few minutes of charging and display shows a green full battery. However, the device can only power on for about 10 seconds before turning off again. Please help me

CrowView Note - Replacement power supply

CrowSloth — Mon, 17 Mar 2025 19:10:18 +0000

Good afternoon, the power supply for my CrowView Note got squeezed in my backpack, and since I had the US version, the prongs for the mains power connection broke off.
I cannot find a replacement on the Elecrow homepage. Are you planning on offering one soon? If not, can you recommend a third party power supply that will work, or give me the details on what I need to buy? It looks like I would need one that can deliver 12V, 4A, and has a 3.5mm barrel plug with the outside being negative. Is that correct?

DIS02050A : CrowPanel Advance 5“ HMI screen - What's the correct connector type?

sirocco — Thu, 13 Mar 2025 18:52:57 +0000

Which is the correct connector for UART0-IN on this board?
the 4 pin connector UART0-IN is larger than the ones supplied for the other Uarts and I2C connectors.
What is the correct spec for the UART0-IN connector please?

DIS08070H : CrowPanel 7.0" HMI ESP32 Display - Cannot compile with LVGL libraries

manstt — Sun, 23 Feb 2025 16:06:33 +0000

Hi,
I bought a 7'' crowpanel I use ArduinoIDE 2.2. 2 to program and compile while I wanted to use the LVGL libraries.

I followed any tutorial spent hours to compile and make it work, of course the Hello World works, but I wanted to use those libraries to create a decent graphics for my project.
Any compilation with this panel fails, only some projects without lvgl work, I'm really exhausted by the thousand compilations with always the same error result and it doesn't continue as indicated in the elecrow wiki:

I followed this link:

https://www.elecrow.com/wiki/esp32-display-702727-intelligent-touch-screen-wi-fi26ble-800480-hmi-display.html#arduino-ide

https://www.elecrow.com/download/product/CrowPanel/ESP32-HMI/7.0-DIS08070H/Arduino_Tutorial/Arduino_Tutorial_70.zip

I added the libraries contained in the zip but this is the compiler result:

Cannot compile with LVGL libraries crowpanel-esp32-7.0

Hi,
I bought a 7'' crowpanel I use ArduinoIDE 2.2. 2 to program and compile while I wanted to use the LVGL libraries.

I followed this link:

https://www.elecrow.com/wiki/esp32-display-702727-intelligent-touch-screen-wi-fi26ble-800480-hmi-display.html#arduino-ide

https://www.elecrow.com/download/product/CrowPanel/ESP32-HMI/7.0-DIS08070H/Arduino_Tutorial/Arduino_Tutorial_70.zip

I added the libraries contained in the zip but this is the compiler result:

DIS08070H : CrowPanel 7.0" HMI ESP32 Display - TOUCH ISSUE

Soumya — Fri, 01 Nov 2024 11:05:00 +0000

So i got a new crowpanel 7 inch V3.0 display with touchscreen and tried to learn the basics through their youtube tutorial but one the 4th lesson i was stuck because the code did upload successfully but i wan unable to draw anything so if someone else has encountered similar issue kindly help me out. (I also checked the panel by uploading the default LVGL interface and the touch did work there so i think the error is in the code or the code provided in lesson 7 .)
