Hi Folks,


I know that its not the most beautiful way to establish a SPI connection but due to Project history I have to implement an SPI bit banging method.




My Problem is now that the GPIO pins (even with fast slew rate) are too slow!


Do you know a way how I can get faster slew rates?




Thank you in advice.

Welcome in the forum, Niklas.


Why bit-banging? Why not use an SPI component?? And I question that the slew rates are bad, What board do you use, which pins?


Can you post your complete project, so that we all can have a look at all of your settings? To do so, use
Creator->File->Create Workspace Bundle (minimal)
and attach the resulting file.
