Not Keil specific; one for the 'C' experts:
Why would one put 'static' variables definitions in a header?
eg, in a header file:
/* * TCO count to temperature conversion table. */ static erTcoTableStruct tcoTableOPUS1[] = { /*{TCO,Temp,} */ {1,-99}, {4,-45}, {5,-40}, {8,-35}, {11,-30}, {16,-25}, {22,-20}, {29,-15}, {37,-10}, {48,-5}, {61,0}, {78,5}, {99,10}, {124,15}, {153,20}, {188,25}, {227,30}, {270,35}, {315,40}, {365,45}, {420,50}, {481,55}, {549,60}, {625,65}, {710,70}, {805,75}, {910,80}, {1010,85}, {1060,88} };
AIUI, the whole point of so-called "header" files in 'C' is to share stuff between source files;
But the whole point of the 'static' keyword (at file scope) in 'C' is to make stuff private so that it is not visible to other modules - ie, not shared.
So I can't see why one would want to have 'static' definitions in a header?!
#ifdef UART_Module // Data Allocation #else // Data reference #endif
But that's where it gets a bit confusing!
The whole point of making something static is so that it can not be externally referenced!
So, in this case, would you have, say:
#ifdef UART_Module static char private_uart_char; #else // No reference for private_uart_char #endif
yes?
