Translating Microchip C18 C to CCS C

[klausdejong]

I am in the process of translating software for the CC2420 radio from C18 C to CCS C.

My question for this moment is: what do the back slashes mean. See code fragment below.

They are line continuation markers. They should be exactly the last character on the line.

In this case it allows the #define to be written over several lines rather than having to put the whole statement on one line as would normally be the case with #define.

You can substitute the CCS function spi_write() for their _SPI_WRITE()
function.

So, the code snippet I posted is their definition for the CCS spi_write()

OK, thanks
