Detailed Description

Touch panel task responsible for interfacing with the touch panel using the panel object.

Implements a finite state machine for touch panel

Constructor & Destructor Documentation

◆ init()

def LabFF_task_panel.Task_Panel.__init__	(	self,
		period_pan,
		panel_obj,
		state_vect_x,
		state_vect_y,
		calib_pan_flag
	)

Constructs a touch panel task.

Touch panel task attributes include the period, panel object, state vectors, and panel flag for calibration

Parameters

period_pan	The period, in microseconds, between runs of the panel task
panel_obj	The panel object of the touch panel driver class
state_vect_x	List used to define state vector x
state_vect_y	List used to define state vector y
calib_pan_flag	A boolean flag used to enable touch panel calibration

Member Function Documentation

◆ transition_to()

def LabFF_task_panel.Task_Panel.transition_to	(	self,
		new_state
	)

Transitions the FSM to a new state.

A function that transitions the FSM to a new state

Parameters

new_state The state to transition to

Member Data Documentation

◆ calib_pan_flag

LabFF_task_panel.Task_Panel.calib_pan_flag

A boolean flag used to start touch panel calibration.

Works with the task panel and user interface to enable resistive touch panel calibration

◆ first_pos_x

LabFF_task_panel.Task_Panel.first_pos_x

Initializes x position variable.

Continuously updated to calculate positional velocity in x-direction

◆ first_pos_y

LabFF_task_panel.Task_Panel.first_pos_y

Initializes y position variable.

Continuously updated to calculate positional velocity in y-direction

◆ next_time

LabFF_task_panel.Task_Panel.next_time

The utime.ticks_us() value associated with the next run of the FSM.

Defines a variable that adds the period to the ongoing timer

◆ panel_obj

LabFF_task_panel.Task_Panel.panel_obj

The panel driver object.

This panel driver was defined in the main.py file

◆ period_pan

LabFF_task_panel.Task_Panel.period_pan

The frequency of the panel task.

Variable that specifies timer frequency

◆ positions

LabFF_task_panel.Task_Panel.positions

Object associated with position read by touch panel.

Uses panel object to update state vectors

◆ runs

LabFF_task_panel.Task_Panel.runs

Sets the number of runs to 0.

Defines a variable to keep track of runs

◆ second_pos_x

LabFF_task_panel.Task_Panel.second_pos_x

Defines x position variable read after position changes.

Continuously updated to calculate positional velocity in x-direction

◆ second_pos_y

LabFF_task_panel.Task_Panel.second_pos_y

Defines y position variable read after position changes.

Continuously updated to calculate positional velocity in y-direction

◆ state

LabFF_task_panel.Task_Panel.state

Sets initial state to State 0.

FSM starts at State 0, where user input is prompted for further action

◆ state_vect_x

LabFF_task_panel.Task_Panel.state_vect_x

A shared list used to define state vector x.

Contains variables for x position, theta y, x velocity, and angular velocity (theta y dot)

◆ state_vect_y

LabFF_task_panel.Task_Panel.state_vect_y

A shared list used to define state vector y.

Contains variables for y position, theta x, y velocity, and angular velocity (theta x dot)

◆ x_velocity

LabFF_task_panel.Task_Panel.x_velocity

Calculates x velocity after position changes.

Change in x position over task period

◆ y_velocity

LabFF_task_panel.Task_Panel.y_velocity

Calculates y velocity after position changes.

Change in y position over task period
