LITL

The LITL library - Linked-list, Input, Timer, Library

The library is meant for avr microcontrollers however the linked list also works on desktop

• INPUT:

  • An input class for avr inputs

  • Supports: Rising Edge, Falling Edge, Filtering (requres castimer)

  • Initialization : INPUT_t example("pin","port", bool invert state); INPUT_t example = INPUT_t(pin,'port letter', bool invert state); If invert state is set to 1, the input's value will be inverted from the PIN register value

  • Functions:

    • bool value(); -> Returns value of the input
    • bool risen_edge(); -> Returns 1 if input went from 0 to 1 from the last function call, the risen edge bit is cleared if this function is called or if input is 0
    • bool fallen_edge(); -> Returns 1 if input went from 1 to 0 from the last function call, the fallen edge bit is cleared if this function is called or if input is 1

• TIMER:

  • An universal timer class, if on interrupt mode, then it will only work on avr (those that use the ISR block).

  • Supports interrupt mode (every timer is incremented in an ISR) or system time mode (time difference)

  • Initialization : TIMER_t your_timer; TIMER_t your_timer = TIMER_t();

  • Functions:

    • uint32_t value(); -> Starts the timer and returns the value
    • void reset(); -> Resets the timer and disables it
    • void set_hook(function to call, calling period, pointer of parameter to send to function); [ ONLY AVAILABLE IN INTERRUPT MODE] -> attaches function to the timer which gets called every specified period, then the timer auto reloads. To reset back into normal mode, call this function again but with NULL, 0, NULL as parameters.

• LINKED LIST:

  • A high language like linked list
  • It uses a TEMPLATE PARAMETER meaning you can tell it what the variable type will be.
  • Does not require the STL library making it compatible with platforms, even those that don't support DLLs.
  • Initialization : LIST_t < data type > list_name; LIST_t < data type > list_name = LIST_t < data type >();
