tired of flashing your embedded project over and over just to modify a few values? So was [Karl], so he composed a text editor that runs on his ARM dev board.
Having trouble wrapping your mind around the need for this kind of thing? He’s actually playing around with eLua, the embedded version of the Lua programming language. In this case the program data are being kept on an SD card. but still, moving that back and forth between computer and embedded project gets old quickly. So he invested the time to write a rudimentary text editor that he interfaces through this terminal window. above you can see the help screen which sets out all of the applications features. right now it sounds like the only gotcha for this is the amount of RAM it needs to run. As it stands, the editor will now work an mbed board, but it works just fine on an STM Discovery.
