I am thoroughly investigating the DSPI class at the moment. Using UECIDE I am using this sketch from Microchip to demonstrate the PmodAD5. Within the sketch is #Included one libraries called AD7193.h and then AD7193.h calls DSPI.h Now, I am trying to understand how this whole arrangement is determining which pins are used to MISO MOSI clock and Chip Selec SS. This is done via some definition in a header called my another header file nested somehow in the serial calling of so many header files. In DSPI there is one particular pin name ( for example ) called PIN_DSPI0_SS which is the SS pin for DSPI0 object. This pin number is somewhere in a header but I cannot find it. I search ALL header files in the UECIDE folder and could find reference to PIN_DSPI0_SS only in the two header files AD7193 and DSPI.h which do not define the PIN_DSPI0_SS but instead refer to its value. I tried to do the same research within the MPIDE folder and found many header files defining the PIN_DSPI0_SS variable. Here is my question: Where and or how UECIDE recognize the PIN_DSPI0_SS definition ? Wich file is it using ? My board MX7 is by default within UECIDE but all folders are pointing to those folders and files that do not define PIN_DSPI0_SS. Is it possible that UECIDE is actually importing some headers from the MPIDE installation (I doubt it) So then where is the header file defining this PIN_DSPI0_SS within my UECIDE folder ?
Thanks for your help

The definition is in the file Board_Defs.h which is part of the board package you installed for the MX7. You will find it in the UECIDE data directory (find it through the help menu).
