The great thing about AVR chips (arduino UNO is an ATmega328P) is that

they are well covered by the GNU toolchain. Having used that the last 12

years of my career, on 68000, PowerPC, V850 targets, I chose AVR over

PIC for our products on that score alone.

On the AVR ATmega16, we just used gas, no gcc, as a quick little

event-driven OS with inter-process queues, plus a suite of macros

implementing a sweet state machine language, was quite convenient for

creating multi-threaded call control firmware. And I always wrote ISRs

in assembler, so you'd know latency down to the instruction cycle.
