Macro Definition Documentation

BACKWARD_DIRECTION

#define BACKWARD_DIRECTION   0x08

Definition at line 72 of file nbgl_step.h.

FORWARD_DIRECTION

#define FORWARD_DIRECTION   0x00

When the flow is navigated from last to first step.

Definition at line 71 of file nbgl_step.h.

GET_POS_OF_STEP

#define GET_POS_OF_STEP	(		_step,
			_nb_steps
	)

Value:

    (_nb_steps < 2)                       \
        ? SINGLE_STEP                     \
        : ((_step == 0) ? FIRST_STEP      \
                        : ((_step == (_nb_steps - 1)) ? LAST_STEP : NEITHER_FIRST_NOR_LAST_STEP))

get the "position" of a step within a flow of several steps

Parameters

_step	step index from which to get the position
_nb_steps	number of steps in the flow
