static bool rc_attitude_sticks_centered ( void  )

inlinestatic

Convenience macro for 3way switch.

Referenced by autopilot_arming_check_motors_on().

Here is the caller graph for this function:

static bool rc_mode_switch ( uint8_t  chan, uint8_t  pos, uint8_t  max  )

inlinestatic

RC mode switch position helper switch positions threshold are evenly spaced.

Parameters

[in]	chan	RC mode channel number
[in]	pos	switch position to be tested
[in]	max	maximum number of position of the switch

Returns

true if current position is the same as requested (and RC status is OK)
