I succesfully simulated A/D timer2 driven conversions in DMA mode on ADuC812 every 20 instructions. As mentioned in datasheet, while in DMA A/D capture mode ADuC812 can't access external memory. But it can be done in uVision2!? So can I access external memory in DMA mode while ADuC812 is still waiting for conversion?
"As mentioned in datasheet, while in DMA A/D capture mode ADuC812 can't access external memory. But it can be done in uVision2!?" That's the beauty of simulation - you're not constrained by these tedious practical limitations...!
