Help with C code syntex

[coolman21]

Hi I ran across code that I need some help with, can someone explain it?


#define BITBAND_SRAM(a,b) ((BITBAND_SRAM_BASE + (a-BITBAND_SRAM_REF)*32 + (b*4)))

#define MBX_B0 *((volatile unsigned int *) (BITBAND_SRAM(MAILBOX,0))) // Bit 0


thanks

in your message you initialize the bit for SRAM and you use the REFERENCE Add. to store the data into the location but you use the help of syntax from the software which you use.

I'm sorry I cannot help you because I'm not aware of this compiler. But you can help yourself just by saying which compiler you are using and what is the target device. This information should also be included in the thread's title.

Cheers!
