I'm not sure I want to dig through all the register level stuff, that's why I use the library.
Consider for a moment what the level conversion circuit is doing, if for example it could back-drive the STM32's output, and how it's implemented. The problem sounds more electrical than software. Consider if you have a common and effective ground.2012-02-24 01:54 AM
Thank you for the answer and suggestion, I will check once again the ground.
The level converter is KAmodLVC, if you are curious this is the product site: http://kamami.com/index.php?ukey=product&productID=63662 And the manual (in polish, but includes schematic): http://www.kamami.pl/dl/kamodlvc.pdf So, let's go with the checking...
