你能在#defines / preprocessor指令中执行固定长度的位反转吗？

I am writing C code (not c++) for a target with very limited ROM, but I want the code to be easy to customize for other similar targets with #defines.

I can enter these by first manually reversing them, but this would be confusing for future use. Can I define some sort of macro that performs a bitwise reversal? code (not c++) for a target with
