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.
CY_PSOC3 // Any PSoC3 device CY_PSOC4 // Any PSoC4 device CY_PSOC5 // Any PSoC5 device (including both 5 and 5LP) CY_PSOC5LP // Any PSoC 5LP device // If you want to get more specific, you can check for the following... CY_PSOC3_ES1 // PSoC3, Engineering Silicon 1 CY_PSOC3_ES2 // PSoC3, Engineering Silicon 2 CY_PSOC3_ES3 // PSoC3, Engineering Silicon 3 CY_PSOC5_ES1 // PSoC5, Engineering Silicon 1 CY_PSOC5_ES2 // PSoC5, Engineering Silicon 2 // You can use them to include code like in the following example #if(CY_PSOC5) FlashLed(); #endif // Note that #ifdef doesn't work properly! It will always evaluate to true.// Don't know why. Always use the directive #if #ifdef CY_PSOC5 // This won't work!!!
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.
// PSOC is defined by adding "-D PSOC" to the compiler build flags #ifdef PSOC #include <device.h> #endif
