Dogxl240-7n will not display any thing unless display is enabled.

I cant get the Dogxl240-7n to display any of the example unless I add enable display in the init sequence.
It is a comment out line.

does anybody know why it is comment out. The display is reflective maybe that is the problem. Is there something else I should do.

All displays are disabled by default. You should call the powersafe off function to enable it.

I believe the command is the no. 20 "set display enable" that sets DC[4:2] which is shades and and on/off. Default value is 110
16 shades and off. The comment out command is 001 on/of(monochrome) as it should be.
I found the commands in uc1611s data sheet https://www.lcd-module.de/fileadmin/eng/pdf/zubehoer/uc1611s_v1_0.pdf

Sorry did not see your comment

I used the command u8g2.setPowerSave(0); It would have saved me some time if it was included in the hello world example but then I would not have known what I know now. Thanks for taking the time to explain.

[olikraus]

In Arduino Environment u8g2.setPowerSave(0); is executed by u8g2.begin(), this is why it is not part of the examples.

I know I found a unstable wiring problem which made be draw wrong conclusion. I rewired the whole thing and now I have no problems.
Great library thanks.
