NETMF : 

.NET Micro Framework 

- real time operation



.NET Micro Framework 이 코딩하기가 편해서 좋다고 하는데

실시간 데이터 처리 하는 곳에 적용할 수 있을까 ??


구글링하다가 찾은 내용인데

NETDUINO 이거 엄청 느리다, 

포트 토글링하는 루틴인데도 

실행시간이 17 ms !!!!


Using NeoPixels with Netduino Plus 2

http://learn.adafruit.com/using-neopixels-with-netduino/overview


But Netduino runs .NET Micro Framework, which means two important things: your code is interpreted, and there is a garbage collector.
Here is the observed signal on the pin. This is a Netduino Plus 2, which runs at 168 MHz, the other Netduino variations all run at different speed.
It takes 17.6 microseconds to toggle that pin. Now go back to the WS2812 datasheet, and you'll realize that it is impossible to meet the timing requirements using Netduino because the signals needs to be under 1 microsecond.
