Getting Started with PiCore

[emz229]

Greetings everyone! I have just switched from raspbian to PiCore and have to say Im very impressed with the 7 second boot time (to console) and see a lot of potential with this project! Im a little curious though about what the capabilities are of this simple install. I will be using the Pi for an embedded project, and would like to know what the kernel is capable of and how I would interface the GPIO pins. Any information on getting started from here would be much appreciated!

Hi emz229

welcome on board. While install is simple it doesn't mean it is less capable that more complicated and bigger systems Its kernel is practically the same 3.2.27 as Raspbian except miner differences required by piCore (for example no loop devices in Raspbian).

GPIO can be handled on the same way. Which language you are planning to use to manipulate GPIO?

I'm decent with c++ and currently learning the details with c. I've read about some people using perl but I don't know the first thing about perl. I guess the question is what language has the most capable libraries? Is there one that's easier to interface the hardware, and what's the data rate capability of the SDI pins? (I'm attempting fuel injection and there's a lot of sensors to gather data from and timing is critical.)

Excellent resources guys thankyou! I will post details as the project progresses!
