I have 2 problem with the on chip DAC:
1/ it run normal (at 1Msps with PDC) on one channel only. But when I use two channel parallel (in TAG mode), the speed I got is just approximately 29Ksps.
The trigger I use here is the Timer counter trigger (trigger every 1uS).
2/When I use DMAC (to copy value from memory (buffer) to memory (DACC_CDR) the max speed is only approximately 29Ksps.
Could anyone please explain why? I need two channel for my application with the speed at least 100Ksps. Any hint, please?
