Support for devices with more than 3 switches

Opened this issue · 9 comments

I recently grabbed a 6 button usb keyboard ( https://www.amazon.com.au/gp/product/B00X76DS80/ ) for some work and was delighted to see it's keycode in footswitch already. It defaults to outputting a b c d e f and works perfectly. I was hoping to reprogram using footswitch rather than booting to Windows and found the footswitch only supports 3 keys. Any chance of an update to support more keys?

sudo /usr/bin/footswitch -r
[switch 1]: a
[switch 2]: b
[switch 3]: c

I can give it a try if someone borrows me the hardware. Also if anyone else want to contribute this functionality, patches are welcome.

patrickkelso commented

Happy to donate. Easier than me trying to code. It's a nifty device for tinkering with automation.

rgerganov commented

Great but I am not able to find a seller that ships this switch to Sofia, Bulgaria. Send me an email to rgerganov(at)gmail.com and we can think how to arrange this. Thank you for your support!

rgerganov commented

I created a six-buttons branch with a simple change that I believe could work. Could you please give it a try:

$ git clone https://github.com/rgerganov/footswitch
$ git checkout six-buttons
$ make
$ ./footswitch -r

Let's try only reading the device for now. If that works, I will push more changes for writing.

patrickkelso commented

Brilliant.

$ sudo ./footswitch -r
[switch 1]: a
[switch 2]: b
[switch 3]: c
[switch 4]: d
[switch 5]: e
[switch 6]: f

rgerganov commented

Great. I pushed one more change, do a git pull and try to program all of the six buttons.

patrickkelso commented

Works a treat. You've made me a very happy man.

piegamesde commented

I purchased this foot switch, which interestingly also has the ID 1a86:e026. It works out of the box, but is wrongly viewed as device with thee switches.

It is funny to say, but I have been trying to get connected with https://pcsensor.com/ but they ignored me ^__^ I said them about this project and this is a good moment to support this project for them. Maybe they need to hear only Chinese?
