# Working Out What PSoC IC You Are Using

PSoC Creator will define the following variable-like macros depending on what IC you’ve instructed it to compile for. These are useful for including IC-specific blocks of code using the preprocessor #ifdef directives. These macros are defined in cytypes.h, which is in the cy_boot folder under “Generated_Source” in the Workspace Explorer window in PSoC Creator. They are included if you include the standard PSoC catch-all header <device.h> into your code.

Note that these are only define once the precompiler passes the line #define <device.h>, therefore there is no way to write code that detects if you are compiling on a PSoC chip, and if so, then including device.h. A way to get around this is to add a compiler macro as a compiler flag (e.g. -D PSOC), and then use the following code.
