I am using MSP430F2619 Microcontroller and doing programming in C..

I have seen below two instructions for DMA operation but i dont know meaning of those...

Please explain below two instructions...

DMA0SA = (void(*)())sample; // Source block address
DMA0DA = (void(*)())&DAC12_0DAT;
 

The syntax looks confused at first sight. We won't expect data addresses casted to function pointers.

I can hardly believe that this is the straightforward way to initialize MSP430 DMA registers. Instead of trying to reproduce possibly erroneous code, why don't you write the intended operation bottom-up, using the MSP430 datasheet and basic C operations?

Where did you pick up the code?
 

Actually i have tried to define register in simple way so many times and in so many ways, but i failed to initialize to define.

i got this code from TI's example code for DMA operation from TI website.

I have define one array and i have to pass first element's address of that array as a source address of DMA, so how i have to write code or simplify above code in simple basic C operation.
