Brian Choromanski 3f4d706c98 Fixing dead links ()
* Fixed typo of 'confid.h' to 'config.h'

* Fixed broken links in docs

* Fixed a lot of dead links

* Removed all dead links that I could not find a replacement for

* Placed knops links back in

* Fixed plank keymaps so that they will compile for planck light

* Https doesn't work on knops.io

* tv44:budi now compiles

* s60_x:amnesia0287 now compiles

* Fixed allocation of key_combos so that narze keymap for planck can compile correctly

* Disabled rgb on ergodone and infinity

* Enabled tap dance so it compiles

* Added return statement so it compiles

* If compiling on light disable extra functionality

* Properly redefined variable so it compiles

* Remove remaining dead links

# Frenchdev : My take on a splitted keyboard for dev and french language
Concept based on
- [ergodox](https://ergodox-ez.com/)
- [katy](https://deskthority.net/workshop-f7/katy-keyboard-or-k80cs-key80-contoured-split-t8524.html)
with the added possibility to connect up to 6 external switches like pedals,
and somewhat like the katy, not all keys are on the same level for easier reach.

- [editable layout on keyboard layout editor](http://www.keyboard-layout-editor.com/#/gists/4480e3ab8026eb7c710a7e22203ef4aa) (keys placement is NOT precise on this)

## Build instructions
docker run --rm -e keymap=default -e keyboard=frenchdev --rm -v D:/Repositories/qmk:/qmk:rw edasque/qmk_firmware
## Laser-cuttable file
There is intentionnaly no hole for the TRRS connector, you are supposed to use a drill for it.
This way if you don't want to use the pedals you don't have a useless hole. Plus it's cleaner.
## Side stickers
You can find my original file here : http://qmk.fm/frenchdev/example_printable_stickers.svg
I used it when training but now I use blanks and the layout is different.
I still uploaded it because I think it can be a good jumpstart for any temporary stickers on the
side of keycaps.
## List of parts
- I2C mcp23018
- [teensy 2](https://www.pjrc.com/store/teensy.html)
- 3 LED, 5mm tall with flat head
- 3 330 ohm resistor
- 2 470 ohm resistor
- 2 TRRS connectors
- 1 [micro usb breakout board](http://www.ebay.com/itm/-/201387922085?)
- 88 cherry/gateron switchs
- 94 4148 diodes
- 34 R4 keys
- 14 R3 keys
- 20 R2 keys
- 22 R1 keys
If you fancy adding pedals :
[these are good enough and cheap](https://www.amazon.fr/gp/product/B00V7WITKI/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1). You also need a RCA connector for each of those to replace the included cable
If you (or your coworkers) find them too loud you can replace the switch inside them.
For once we don't really care about what's inside :)

We use pull up resistor for SCL and VDA, see https://github.com/ErgoDox-EZ/docs/blob/master/ErgoDox%20EZ%20Schematic.pdf for example
The connector is a standard TRRS (jack with audio + mic)
Diode direction is row to column
