gpio_mouse_device

gpio_mouse_device is a kernel module for registering a gpio_mouse device.

Usage

modprobe gpio_mouse_device up=GPIO down=GPIO left=GPIO right=GPIO bleft=GPIO

Arguments

• up (required)
  GPIO line for up value
• down (required)
  GPIO line for down value
• left (required)
  GPIO line for left value
• right (required)
  GPIO line for right value
• bleft (required)
  GPIO line for left button button
• bmiddle
  GPIO line for middle button
• bright
  GPIO line for right button
• scan_ms
  integer in ms specifying the scan periode (default=10)
• polarity
  Pin polarity, active high or low (default=0 high)
• pullup
  Enable internal pull up resistor for all (only on Raspberry Pi)
• pulldown
  Enable internal pull down resistor for all (only on Raspberry Pi)
• verbose
  0 - silent (default)
  1 - print values to kernel log
  2 - more output

Example

Switches is active LOW and uses the internal pullup resistors

modprobe gpio_mouse_device pullup polarity=1 up=23 down=17 left=18 right=21 bleft=22
