Todo

over lined are done

Low level components

Pins

• output pin
• input pin
• reverse pin
• led (methods on/off)
• safe pin/protected (track pin.mode and change or fail)
  • callback function to call if safety is needed. Can be used to debug that code, /should be/ working :P
  • safe output (only output operations)
  • safe input (only input operations)

Analog pins

• analog digital conversion
• gain
• reference
• analog comparator
• internal temperature sensor
• single / free running modes; async and sync modes?
• auto start on interrupt trigger
• interrupt on complete
• work on sleep
• DIDR0 – Digital Input Disable Register 0

Interrupts

• external (pins)
• internal
• class interrupt: http://jennaron.com.au/avr/classinterrupts.html

Other

• atomic 16 bit writes
• functions for:
  • bit counting
  • for each byte in bigger unit (taking care of endianes) (does autounion do this?)
• Errors (example in I2C) using setjmp and longjmp in setjmp.h or exceptions

Failed / Not possible

• template arguments from constructor (Not possible. look at make_pair, back_insertter)
