Which DAC will you use?
If you cannot update them simultaniously, it will not work.
Then you are back at post 1 of this thread.
I also tried the MCP4922 DAC and applied the LDAC function. (See post#45)
It worked but way, waaaaayyyy too slow.
I haven't looked into any specific DACs yet. This thread has just started me thinking about it.
If the micro has 2 ports that are sequentially mapped in memory you could write to them simultaneously by using a pointer that's 2x the size of 1 port.
For example if p1 is at 0x0000 and p2 is at 0x0008 you can write to both ports using a int16 pointer to 0x0000
BionicBadger does that sound right?
I don't mean to through the conversation off topic I just really like the idea. It seems like at that point the limiting factor would probably be the DAC.
