Confused????? and then some but I do not expect to get it on the first go around! :) Best part of this is I will learn a great deal which keeps my ...

Thanks guys. I will start fresh in the morning and breadboard up a single FC-16 which is the 8 x 32 module. The data I hopefully will receive will b...

Sorry to get you guys involved. I will figure this out in time. I am retired so do have plenty of time. Thanks again for your guidance. Regards - ...

Here is where I started. I have two FC-16 modules which will not be connected together. Two separate displays. Thanks everyone.

Its been a very long time since I did programming. Learned on basis and forgot every bit of it. Admit got a lot to learn today but I am a quick study ...

Never did buffers before so all new to me. I am still crawling however I do appreciate all your help. Hardware connection: On Mega MOSI ...

Do not see what is in your image however I bet it is included in one of the required libraries. spi.h ?

Code is not one of the built in Arduino scripts. Found it on one of the learning sites. Sorry - do not see the 0 above. Above where or what?

Ron - yes I am using an example code. Not sure but I think the pin you are referring to is the CS pin. ( Chip Select ?? ) I will look. Not familiar ...

Thanks Ron. Sounds simple but not for me just learning all this. Both FC-16 modules will be on one SPI bus so I guess I need to research how to steer ...
