    SPI Bit-Banging

    niklas.lehrke

      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.
