Thanks for the feedback. Main problem is, that i do not own this display. So i can not do any tests on it.Oliver
I have ordered the same display from this china seller. Usually it will take some weeks, but once it is here i will verify this.Oliver
Interesting.So they use I2C without acknowledge, because SDA can not pull the line low, as I suspected.But they use a library with software I2C that can be used on any pin ?I clicked the download link, but did not get a file.
