Interrupt

Pin Based

InterruptIn => create InterruptIn connection to specified pin
rise => attach function for rising edge
fall => attach function for falling edge
mode => set interrupt pin mode
Except p19 and p20
0 if < 0.8V and 1 if > 2V
Default interrupt mode = pull-down resistor

Time Based

Repeating Interrupt
Ticker

One-Time Interrupt
Timeout

mbed 11U24

No PWM and no analogout
http://mbed.org/handbook/m0-release
- Power the whole mbed from USB, as normal. This takes 60mA - Power the whole mbed from Vin, as above but with a 4.5v-9.0v range. This also takes 60mA - Power *just the LPC11U24* from VB. This has the range 1.8v-3.3v, and will take 16mA normally, and will drop to about 3mA in Sleep and 800uA when in Deep Sleep.

Strings

array of characters
last character = null character (has value of 0 and represented by \0)
string constants or string literals = " " ;
strcpy(to, from);
strcmp(a, b);
int len = strlen(var);
