Variable Documentation

U8 last_direction

Window operating direction during last operation (according to command).

Range : [DOWNWARD, UPWARD]

Definition at line 59 of file window_lib.c.

Referenced by Read_Eep_WindowParameters(), save_window_parameters(), and window_ctrl().

U8 direction

Window operating direction (according to command).

Range : [DOWNWARD, UPWARD]

Definition at line 63 of file window_lib.c.

Referenced by window_ctrl().

signed char ctrl_state = STOP_STATE

Window-lift Control state (see Window lift control state machine definitions).

Definition at line 66 of file window_lib.c.

Referenced by force_window_state(), get_window_state(), save_window_parameters(), and window_ctrl().

U16 position

Window position buffer.

Range [0 to down] 0 is origin at top of the window down is the max registrable hall sensor edges

Definition at line 72 of file window_lib.c.

Referenced by blocking_point(), Read_Eep_WindowParameters(), and window_ctrl().

U16 ref

Computed current reference ( I(A) <-> ADC * ADC gain ).

Range : [0 to (current measured values) * (ADC gain)]. It's the reference to be compared with current*gain (ADC values) to detect a pinch. Computed according to derivative speed and measured current.

Definition at line 78 of file window_lib.c.

Referenced by blocking_point(), init_window_size_position(), and window_ctrl().

U16 current

Current Image: Has to be filtered (meaned) for the algorithm to work well.

Range [0 to (current * ADC gain)]. To be compared with reference current value (ref)

Definition at line 83 of file window_lib.c.

Referenced by blocking_point(), init_window_size_position(), and window_ctrl().

U8 pinch_threshold

Pinch Threshold: Must be parametred by user (in Newton).

When nothing is paramtred in eeprom, it is set to PINCH_THRES default value. It is stored/recalled to/from eeprom. (see Default Anti-pinch detection parameters)

Definition at line 88 of file window_lib.c.

Referenced by Read_Eep_WindowParameters().

U16 pinch

Normalized pinch threshold according to gain (motor & ADC parameters).

Pinch is computed by eeprom parameters reading routine, using pinch_threshold and gain to be directly compared to acquired current values.

Definition at line 94 of file window_lib.c.

Referenced by blocking_point(), get_block_point(), init_window_size_position(), save_window_parameters(), and window_ctrl().

U8 gain

Global gain to determine pinch value.

Definition at line 97 of file window_lib.c.

Referenced by Read_Eep_WindowParameters(), and save_window_parameters().
