Closed giecuk closed 4 years ago

giecuk commented 6 years ago

hello, what should i change if my oled not display anything, it's not broken oled, because if i used another library it will work.

Make sure you don't forget to set these:

sendCommand(SETVCOMDETECT); //0xDB, (additionally needed to lower the contrast)
sendCommand(0x40);          //0x40 default, to lower the contrast, put 0

On some displays that makes the difference between working and not working.

See also my PR: #171 That includes about all the PR's and suggestions made here and elsewhere about these displays.

Where do you set those?

I added it to setup() but got the following error:

'sendCommand' was not declared in this scope

I guess a lot may have changed since I added that comment. Just about all files in the repository have changed since.

Maybe you could share a bit of your code indicating where you call this sendCommand?
