Footswitch
Command line utlities for programming PCsensor and Scythe foot switches. There is support for both single pedal devices and three pedal devices. Use the footswitch binary for the following combinations of vendorId:productId:
0c45:74030c45:7404413d:2107
Scythe switches with vendorId:productId=0426:3011 can be programmed with the scythe binary. You can find the vendorId and productId of your device using the lsusb command on Linux.
The same kind of foot switches are used for building the popular VIM Clutch.
Building
The programs are using the hidapi library and should work on Linux and OSX. To build on Linux:
sudo apt-get install libhidapi-dev
git clone https://github.com/rgerganov/footswitch.git
cd footswitch
make
sudo make install
To build on OSX:
brew install hidapi
git clone https://github.com/rgerganov/footswitch.git
cd footswitch
make
sudo make install
Usage
footswitch [-123] [-r] [-s <string>] [-S <raw_string>] [-ak <key>] [-m <modifier>] [-b <button>] [-xyw <XYW>]
-r - read all pedals
-1 - program the first pedal
-2 - program the second pedal (default)
-3 - program the third pedal
-s string - append the specified string
-S rstring - append the specified raw string (hex numbers delimited with spaces)
-a key - append the specified key
-k key - write the specified key
-m modifier - ctrl, shift, alt, win
-b button - mouse_left, mouse_middle, mouse_right
-x X - move the mouse cursor horizontally by X pixels
-y Y - move the mouse cursor vertically by Y pixels
-w W - move the mouse wheel by W
You cannot mix -sSa options with -kmbxyw options for one and the same pedal
_
scythe [-123] [-r] [-a <key>] [-m <modifier>] [-b <button>]
-r - read all pedals
-1 - program the first pedal
-2 - program the second pedal (default)
-3 - program the third pedal
-a key - append the specified key
-m modifier - ctrl, shift, alt, win
-b button - mouse_left, mouse_double, mouse_right
You cannot mix -a and -m options with -b option for one and the same pedal
Examples for PCsensor
footswitch -r
read the persisted function in each pedal and print it on the console
footswitch -k a
program the second pedal to print the letter 'a' (also work for single pedal devices);
as a general rule you don't need to specify -1, -2 or -3 if you have only one pedal
footswitch -1 -k a -2 -k b -3 -k c
program the first pedal to print 'a', second pedal to print 'b' and third pedal to print 'c'
footswitch -1 -k esc -2 -k enter
program the first pedal as Escape key and the second pedal as Enter key
footswitch -1 -m ctrl -k a -3 -m alt -k f4
program the first pedal as Ctrl+a and the third pedal as Alt+F4
footswitch -m ctrl -b mouse_middle
program the second pedal as Ctrl+<middle_mouse_click>
footswitch -s 'hello world'
program the second pedal to print 'hello world'
footswitch -s 'hello' -s ' ' -s 'world'
this will also program the second pedal to print 'hello world';
you can specify multiple -s options and each option will append to the resulting string
footswitch -a esc -a i
program the second pedal to produce Escape and then the letter 'i'
footswitch -s ls -a enter
program the second pedal to print 'ls' and then hit Enter
footswitch -S '29 C'
program the second pedal with the specified 'raw' string (hex numbers delimited with spaces);
you can find the hex code for each key at http://www.freebsddiary.org/APC/usb_hid_usages.php
footswitch -1 -x 10 -2 -w 15 -3 -y -10
program first pedal to move the mouse cursor 10 pixels left;
second pedal to move mouse wheel 15 units up;
third pedal to move the mouse cursor 10 pixels right
Examples for Scythe
scythe -r
read the persisted function in each pedal and print it on the console
scythe -1 -a a -2 -a b -3 -a c
program the first pedal to print 'a', second pedal to print 'b' and third pedal to print 'c'
scythe -1 -m ctrl -a h -a o -2 -m alt -a f4 -3 -b mouse_double
program the first pedal as Ctrl+h+o, the second pedal as Alt+F4 and the third pedal as double click
Hardware issues
Several people have reported misbehaviors with the PCsensor footswitch due to hardware issues.
If the pedal is continuously sending a keypress without being pressed, then most probably some of
the elements do not make good contact with the PCB. Follow the instructions contributed by @krasiyan
on how to verify and fix this.
