virtuoso-joystick

A barebone skill/python bundle to provide joystick support to cadence virtuoso

WARNING This is currently highly experimental

Quick and dirty install

• cp both src/* files to the working directory
• launch cadence virtuoso
• in the CIW, execute load("joystick.sk")

Adapt to your needs

Joystick buttons

• the skill function ButtonChange(button_number, button_value) in joystick.sk gets called whenever a button state changes. Implement your code here. button_value can take the two values 0 (released) and 1 (pressed)

Joystick movements (a.k.a. axes)

• Whenever the position of one of the joystick axes change, the function JoystickChange(axis_number value) in joystick.sk is
  called. This is called only once at each joystick position change. Implement your code here. value is an integer between -32767 (full movement in one direction) and 32767 (full movement in the other direction). A value of 0 indicates the resting position

• You can configure each axis with a repeat mode. In repeat mode, whenever the joystick isn't in its resting position, the function JoystickValue(axis_number value) in joystick.sk is called repeatedly (with a higher frequency when you apply a stronger force). This is useful for, e.g. scrolling when you want the scrolling to get faster whenever you apply stronger pressure to the joystick. The value argument is the same as above.:w

Configuration of the axes behavior is done in joystick_reader.py/main() function.

The following configuration declares axes 0 and 1 to be lin_repeat mode (i.e. with a linear progression of the delay between two JoystickValue events). The values 0.1 and 0.5 define the fast frequency (1/0.1 second) when the joystick position is at its max and the slow frequency (1/0.5 second) when the joystick position just leaves its resting position.

The third axis (axis 2) is in mode no_repeat: JoystickValue won't get called for it but JoystickChange will be called whenever the joystick position changes.

    config = {
              "axes": {
                  0: ("lin_repeat", 0.1, 0.5),
                  1: ("lin_repeat", 0.1, 0.5),
                  2: ("norepeat"),
              }
