Hello! As this pogo_v4.h include file is used only in pogo_v4.c source file and contains only few defines, you can move all these defines directly into pogo_v4.c source file. There is no need to export these constants if they are not used by other files or modules.
Sure, but that'll make the .c file harder to read? We've been using the .h file since the old days, I think mostly for readability. This is a small header file, but for some other boards, the header file is quite large.
Thanks, Tony
