Hi all, I have a question about the DAC driver for Tmote sky node.
Can anybody tell me some information about following definition? I cannot find useful info in msp430 data sheet, neither in the comments for the driver code. (I am very appreciated that any nice guy can tell me where to find a detail description about the registers in msp430f1611) I find following in usr/local/mspgcc/msp430/include/msp430/dac12.h #define DAC12GRP 0x0001 /* DAC12 group */ what's dose this group mean? #define DAC12DF 0x0010 /* DAC12 data format */ what's the two types of format? #define DAC12LSEL0 0x0400 /* DAC12 load select bit 0 */ what dose 'load select' mean? #define DAC12LSEL1 0x0800 /* DAC12 load select bit 1 */ Another question is that: Is it a must to use DMA while using DAC for Tmote Sky? Thanks for your help. Yang
