Library required settings

In order to tell which board you use, you have to set some defines for it. These defines are also used in other libraries to automatically identify used board. For example, my SDRAM library checks for board define to know how to init SDRAM settings for different boards. So, in your defines.h configuration file, set one define according to these available:

When using my examples for Keil uVision, you won’t see these defines in defines.h file. They are set in “Options for Target” in IDE!
