First let me say that I am completely new to hobby electronics so please be gentle.
I ran across a project that someone else had done using an RN-XV module that I wanted to try out. They had posted all of the code that they used so I put everything together and just copied and pasted the code. Now I’m seeing the possibilities for this little unit but I can’t make sense of how to utilize the additional GPIOs on the module. I’ve looked through the user manual and data sheets and I can see all of the commands to use but I can’t figure out how to control specific GPIOs. It says to use the bit-mapped register for the GPIO but it doesn’t go into what registers are associated with each GPIO, or at least I couldn’t make sense of it.
Does anyone know where I can get some additional, more detailed information on how to control this module? Or maybe care to give a short explanation that can get me started.
Thanks.
