C++11 on Arduino

With the release of the development version of the Arduino IDE software using GCC 4.8.1 (see here), it's possible to enable C++11 support by adding the flag -std=gnu++11 to the end of the compiler.cpp.flags line within hardware/arduino/avr/platform.txt.

This lets you compile:

void setup() {
    int array[] = { 1, 5, 2, 7, 9, 33 };
    // range-based for loops
    for (int i: array)
    // lambda expressions
    [] () { Serial.println("Lambda"); };

along with other C++11 goodies.

LaTeX cheat sheet

I'm a fan of LaTeX for typesetting and used it to produce my own book, which was a mixture of mostly text with a few black and white illustrations.

Mostly for my benefit, so I can find it again easily, here is a link to an A4 Linux cheat sheet.

Verbing weirds language

According to Wikipedia, dizzy has been "verbed", but quite how I'm not sure how. Ghastly.

New Arduino board - the Zero

Tre, Due, Uno...and now the new Arduino Zero!

Great to see a new Arduino board in the original form factor, but with a bigger, faster ARM core CPU, with embedded debugger, true analog out, 32kB RAM, 256kB flash, and 1,000 elephants*!

Running at 3.3V will mean a few changes to existing shields and support circuitry, but overall I think this is a great addition to the range. Looking forward to the Zero Mini...

* - One of these isn't true.
