I don't know anything about real-time embedded OSes, and I'm definitely interested in learning more. I found this so far: http://tronweb.super-nova.co.jp/itron.

I don't know anything about real-time embedded OSes, and I'm definitely interested in learning more. I found this so far: http://tronweb.super-nova.co.jp/itron.html http://tronweb.super-nova.co.jp/itron.html I have to say that the horrendous UI of Japanese consumer electronics in the 1980's and 90's seems quite closely linked to Japan's slide from the top of that market. Seven years ago, when I first visited Japan, everyone used a clamshell phone with a godawful LCD interface. Today, everyone has an iPhone or iPhone clone (aka Korean or Chinese Android device). Even today, mobile carriers usually have a "Japanese Only" section on their website for the nationalists who insist on buying Japanese, and, sadly, those phones are very underwhelming by any reasonable standard in 2016.
