I have several projects using the AW, but it looks like its going to be superceded by the AC. The AC seems to be a little cheaper and its a Flexis part, so it might make sense to switch at some point.
But, I would want the firmware to be backwards compatible, as the ones in the field may need updating sometime in the future and I would not want to maintain 2 sets of software, let alone have the user try to determine which processor is installed.
I looked thru the datasheets and assorted docs, but only got partial info. It seems that the AC has a few more peripherals.
So, to the question: Has anyone made the switch? What sort of hidden gotchas are in there? Is there a way for the firmware to determine what hardware its running on in case there are differences that need to be accomodated?
The first application I was considering uses the AN2295 bootloader, no timers/TPM channels , internal timebase, internal flash to save data, both UARTS, and some analog inputs. internal oscillator only.
