Im having a problem with my current project.
I am using a 128x32 oled for stats and an RTC. I also have a logic level shifter with a plug attached for optinal extention(like lcd, etc) running on 5V.
But when i have no device attached to that same shifter the I2C test gives me all Ids(as if all ids where used) and in so chrashes my python script for the oled.
I cant just turn off the shifter because it also shifts SPI and so sometimes the I2C is still unused.
Is there away to maybe pulldown the I2C pins on the 5V end to stop the problem?
