#ifdef, what device?

Hi,

I want to have my code load different (well obv) settings based on what PIC has been used when compiled, i.e. 16f877A or something else.

What's the pre-processor arg to check for this?

something along the lines of,

#ifdef <16f877a>
...
...
#elif <16f648A>
..
..
#endif

I have a couple hardware profiles that are selected by commenting out some defines. I *could* in each setup a define such as #define _16F877A, and follow with the ifdefs. Was wondering if there was something inbuild that would already 'realise' what device was being used via the #device para in the include files for the devices.

Thanks!

#if getenv("DEVICE")=="16F877A"
... code for this device
#else

etc..

Best Wishes

I prefer Ttelmah solution however this also works
#if __device__ ==8720
both are in the manual. It is better to look things up in the manual before posting perhaps you missed them or didn't search under key word device

Thanks, the getenv() method seems the cleanest, cheers!
