alt Hacker NewsYeah - I don't really consider this comparable for my uses which rely heavily on the DSP and processing power of the Teensy itself either.
Drama and whatnot aside I'm not really sure why anyone would buy the (considerably more expensive) Teensy over something RP based if RP was suitable for their needs already.
Interestingly despite being a Teensy fan I have found myself reaching more towards the RP when I can because I can't stand the Arduino API and much prefer the RP SDK. I do use Teensy without Teensyduino (Makefile based) and also a bit of the CMSIS-DSP stuff directly - but it's kinda clunky IMO.
I've been interested to hear more about use cases for these "hybrid" MCUs, can you share a bit about why you chose that over something like a Cortex-A running linux, or an SoC with -A and -M cores?
