* 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.
|
|

## 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
