You asked what ARM could replace an AVR. I said there were lots of ARM Cortex-M based microcontrollers that could. Your response makes no sense. > No chip that needs an OS can truly replace an AVR They don't need an OS. > No chip that takes more than two seconds to boot up can truly replace an AVR No boot up time. They start running your code right away. > No chip with a 2,000-page data sheet can truly replace an AVR. Maybe more like a few hundred. Just like an AVR datasheet. > No chip that requires binary blobs to do anything interesting can truly replace an AVR. They don't. They don't even have GPUs. > No chip that's available only in a BGA or other leadless package can truly replace an AVR. There available in hand-solderable TQFP packages. There are even a couple of DIP ones (8-pin and 28-pin). > No chip that requires a 1-gigabyte toolchain installation I'm pretty sure GCC isn't anywhere near a gigabyte, but it's also the same toolchain used with AVRs. > (or, Woz forbid, a "cloud"-based toolchain) can truly replace an AVR. While they exist, they're not in the slightest bit necessary. > no chip that wasn't explicitly designed to be easy to use by nonexperts in a hardware project can truly replace an AVR. AVRs were also not designed for non-experts. Try reading a datasheet sometime and try to tell me that's written for non-experts. > Even lack of 5-volt compatibility has proven a handicap Lack of 5-volt "compatibility" is an interesting spin on what is essentially a legacy. One could just as easily argue "lack of 3.3V compatibility". Sounds like you need to educate yourself a bit. There's more to microcontrollers than Arduino.
