"Typically I am there to rail against the people that talk about using threads and an RTOS for such things, when a simple polled loop that looks like a primitive video game is much more clear and effective. " Yess, I finally feel vindicated. I've been having this argument with embedded people since forever. I was of the opinion that if million line big boy PC apps can make do with just one thread, having fifteen threads and synchronizing between them using mutexes and condition variables on a microcontroller with 64kb RAM is just bonkers. For some reason, the statement that a while(true) loop + ISRs + DMA can do everything an RTOS like FreeRTOS can do, can rile up embedded folks to no end.
