How to detect if some stream is defined?
E.g.
| Code: |
/*
This example not works.
#ifndef directive not detects RF24_SPI stream
*/
#USE SPI(SPI1, FORCE_HW, BAUD=4000000, STREAM=RF24_SPI)
#ifndef RF24_SPI
#USE SPI(SPI2, FORCE_HW, MASTER, BAUD=4000000, MODE=0, STREAM=RF24_SPI) //<-generate an error
#warning RF24_SPI initialized as SPI2 //<-this warning is shown-up
#endif
|
Thanks

I'm not sure if the stream can be recognized outside of the #use rs232()
library. But you do everything you want with conditional define
statements, such as #ifdef, #else, #ifndef, etc., by just using normal
methods. |

Dear Mr. PCM,
but, do you know how to detect if some STREAM was initialized or not?

I just wanted to offer a small tip. I don't want to spend more time working
on this type of problem. |
