I bought one of the M5Stack's devices expecting it would work out of the box with my ESP-IDF code, I was quite disappointed to realize that I had to adapt their code myself. I'm hopeful that this merger encourages M5Stack to build their software into the ESP-IDF framework.
The only m5stack device i've used is the "cardputer", which supports (a slightly old version of) ESP-IDF out of the box. Honestly, I think ESP-IDF is a solution to a non-problem and wish espressif just shipped a toolchain and maybe a linker script like every other embedded systems developer, but I'm currently working to tease that out so i can get to a sane development environment. I think environments like Arduino and ESP-IDF tend to encourage half-assed code, to be honest.
