SPI Bit-Banging

[Anonymous]

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.
