## Detailed Description

Definitions of the failed assertion 'blink codes'.

This file defines the known "die blinking codes" that may occur.

When any of a large class of programming errors is detected, the SFB will stop normal operation and repeatedly display a 'blink code' that may help in determining what went wrong.

The blink code is preceded by blinking of the face LED's in a NS-EW-NS-EW-NS sequence, followed by 0 to 6 red flashes, then 0 to 6 green flashes, and finally 0 to 6 blue flashes; then the entire sequence repeats.

If an error flashes, say, 1 red, then 3 green, then 5 blue, that corresponds to

      BLINK_CODE(1,3,5)

Searching for that blink code in SFBErrors.h then reveals that an E_API_REFLEX_FULL error has occurred.

Notes:

- All codes of the form BLINK_MAP(0,X,Y) -- i.e., with no RED flashes -- are reserved for sketch use!

- The range of blinks per color is 0..7, but only 0..6 are used so far; 7 in any position is reserved for expansion

- Normally once a blink code occurs, it will blink indefinitely, until the SFB is reset. But if the RF_OKAY_NEW_GUY reflex flag is set, then after a small number of blink code displays the SFB will attempt to reboot automatically.

## Define Documentation

#define BUG | ( | message |  | ) | BUG_CODE(message, E_BUG_UNSPECIFIED_BUG)

Kill the system, leaving it blinking E_BUG_UNSPECIFIED_BUG.

Additional message may be visible if the reflex flag RF_DIE_ALOUD is enabled via SET_REFLEX_FLAGS.

Parameters:

  | message | a last message to possibly make available for debugging

Returns:
  Does not return

#define BUG_CODE | ( | message,
|  | code |  | ) | _apiError_(code, #message " - " __FILE__, __LINE__)

Kill the system, leaving it blinking code.

Additional message may be visible if the reflex flag RF_DIE_ALOUD is enabled via SET_REFLEX_FLAGS.

Parameters:

  | message | a last message to possibly make available for debugging
  | code | a 'blinkcode' to display (see BLINK_MAP)

Returns:
  Does not return

#define BUG_IF_CODE | ( | code,
|  | condition |  | ) | do { if (condition) BUG_CODE("", code); } while (0)

Conditionally kill the system, leaving it blinking code, if condition is non-zero.

Parameters:

  | code | a 'blinkcode' to display (see BLINK_MAP)
  | condition | an expression to evaluate that produces a bool value

#define BUG_UNIMPLEMENTED | ( |  | ) | BUG_CODE("Unimplemented",E_BUG_UNIMPLEMENTED)

Kill the system, leaving it blinking E_BUG_UNIMPLEMENTED.

Returns:
  Does not return

#define E_API_RESOURCE_EXHAUSTED BLINK_MAP(2,2,0)

Some required resource has run out.

Since:
  0.9.18

#define E_BUG_STACK_CORRUPT BLINK_MAP(6,0,3)

Bug: Flag value at stack end was altered.

This can be caused by either a stack overflow, or a global variable buffer overflow. Check getMinimumStackSpace().

Since:
  0.9.10
