@hwtaro9 yes, they are located on the M_Bus

Nice work.
Can you write up a guide to Using images on Hackster.io based on what you found as it would be easier to find instead of searching this forum in the future.

Not a bug per say but more of a visual suggestion.
The last block(Get Label Width) in the core2's LVGL Table block needs moving about 5 pixels in to light up with the other blocks.

what's the voltage when the sun comes out?
you would be better of using a VMeter unit instead of the adc to measure voltage as under high sun it could be overloading the 3,3v max input pin causing the reset.

@epollari Nice work in sorting it out.

@belsonc oops sorry for causing issues. When you power on the ink or paper immediately push up on the navigation switch on the side!
When I wrote that I didn’t think that new users would know how to bypass the program to get into the menu.
Thanks for pointing out the mistake on my part!

Is the ENV III plugged into the red port?

@alexanders thanks to you question, I have now added a paragraph about this to my book which will hopefully get an update by the end of the month!

The V2 is designed for that however there are a few issues you need to overcome.
1, it does not connect to the pi like a pi camera.
2, there is a steep learning curve when it come to programming.

if you were looking for a quick fix for image recognition then I'm sorry it cant help. I have been struggle to understand it for a long time and I still have the V1

Unfortunately due to the component crises the RPI issue is bad however wave share do a better resolution camera replacement to the official RPI camera2

I'm not sure what changed but last year something did and you can only run one instance at a time connected to a controller. If you open a second connection to another controller it does in deed cause problems, which is a pain as I used to run two controllers at a time for testing.
