epaper.refresh 5

It's from Ciciocb's examples. I have no idea what mode 5 does..

From the help file it seems that the second parameter is for temperature. Would that have to do with room temperature which influences refresh rate?

Do you have a touch panel connected?

I have one module that does and one without. The module with no touch panel crashes if a program doesn't start with
print touch.setup.

From then on the module keeps sending 'touch readBytes error!" to the Serial Monitor.

On the module with touch panel it works ok.

Hi Hendrix

I thought touch was included, so i ordered without touch, i am expecting the panek.
on my side i still have line and correct black screening issues on one side of the epaper.

if i let it unplugged for a long time, works ok after, but the more and more you clear and screen other stuff, the more the color is not perfect.
I suspect if to have an issue...

When operating from battery I get a lot of black lines. These disappear when powering from USB.
