[GB] TMK FC980C Alt Controller [Leftover sale]
« on: Tue, 13 June 2017, 20:20:55 »
What is this?

This controller replaces original controller of Leopold FC980C and make it programmable with my TMK firmware. Keymap Editor is also offered for ease of use.





Note: R4 and C10 are intentionally unpopulated.




Original controller of FC980C looks like this, for reference.
More



I'll share technical infos and findings I get in this project with community, also firmware source codes also will be published as opensource/freesoftware under GPL, immedately as possible. I don't decide it yet but controller PCB design files will be shared under license like CC-BY-NC-SA after certain term. I believe this GB can contribute to keyboard community to some extent in terms of these points.

You can discuss technical topics here: https://geekhack.org/index.php?topic=90681.0

Post your question or suggestion here. You can email me if really needed.

Thanks


Production will be closing
Demand for this controller is very little now, next round won't happen anymore. I'll stop producing this controller when components in hand runs out. At least 24 pcs can be assembled before the shutdown, it is enough for demand for several months probably.

You can still get this controller from Letfover sale, see below.

Note
- This is NOT compatible to FC980M https://geekhack.org/index.php?topic=90104.msg2448274#msg2448274
- This controller doesn't include USB connector. http://i.imgur.com/m41F7vL.jpg
- On controller PCB R4 and C10 are intentionally unpopulated.


How to install
You have to void warranty from manufacturer to do this mod, of course.
More
Open case
Break warranty seal sticker

and unscrew three bolts on bottom.

Crack it open using tool like phone openner or plastic card with care.



Mate/unmate connector
Cable harness between boards is very short and you have to be careful when mate/unmate it.


See this instruction to handle this connector: http://i.imgur.com/lSJ5Klm.png


Use fingertip or nail for this connector and unscrew to remove controller board.



Install controller board
Fixed controller board with two screw.




TMK Keymap Editor
You can configure key mapping and download firmware with web browser. Chrome is recommended.



http://www.tmk-kbd.com/tmk_keyboard/editor/unimap/?fc980c


How to flash
The Controller has ATmega32U4 as a microcontroller. Press button on bottom to turn into programming mode.
More


To flash firmware you need tool like FLIP or dfu-programmer, refer to this wiki page for detail.
https://github.com/tmk/tmk_keyboard/wiki#flash-firmware


Build from source codes
Build firmwre yourself when TMK Keymap Editor is not enough for your need.

You can find source codes here:
https://github.com/tmk/tmk_keyboard/tree/master/keyboard/fc980c

Check wiki for how to build firmware:
https://github.com/tmk/tmk_keyboard/wiki#build-firmware


Troubleshoot



Past runs:

Second batch[Closed]
More
Next batch of pcbs will be ordered and assembled in next several weeks.
You can get controller from this batch now.(2017/07/28)


First batch[Closed]
More
Update:
2017/07/28 controllers were tested and ready, they will be shipped in a week.

MOQ(Minimum Order Quantity) is 15 and closing date is 15 July. (Some extras will come you can still order.)
(We hit the MOQ!!!! 07/03)

Once orders reach the mark I will buy the keyboard and start development immediately, it will take one or two month. This GB won't happen and your money is fully refunded unless the MOQ is met til the closing date. I'm almost confident that I'm able to do this job but you are also fully refunded if I fail to deliver controller for whatever reason. I think there is virtually no risk for you to join this.

Personally don't need one, but I've shared this around to try and garner some orders.
QFR | MJ2 TKL | "Schumiboard" | "Bulgogiboard" (Keycon 104) | MIRA SE | Weaven (MOD-M) | TGR Alice (68g vints) | MEME | Keycult No 1 (when it ships) | Southpaw Fullsize (when it ships) | I mostly use the Alice, but the Mira gets some use

has puddsy gotten an award for person most involved with things hes not involved in at all, yet?

No the FC980C is topre, completely different electronics.

EDIT: Linked the thread in my sig maybe it'll bring in a few more people. I don't personally need the extra customization but I am typing this on a FC980C :D

Just to be sure, this is compatible with both the 660c and 980c ? If yes I will probably pick one up

Contoller of the two keyboards are not identical physically at least.

GB Update:
Hi folks,
Thanks for your help.

I examined FC980C and found it is almost equivalent electrically, next wrote initial firmware and verified it with FC660C Alt controller.




I designed pcb for the controller these days and am about to order pcbs now.



Everythig goes well so far.

No leftover from first batch. Second batch will occur in next several weeks.

Actually I'm having an issue with programming the board. It seems as though the LCtrl key is outputting whatever I program the RCtrl key to.




For example, if I program the original RCtrl to "A", my LCtrl key will output "A", no matter what I map LCtrl to. It's happening with both of my controllers, so I'm not sure what the problem is.

Thanks for reporting, I found a bug in firmware and just updated source code and keymap editor now.

Try keymap editor again please. You may need reload page(F5 or Ctrl+F5) in browser to use new editor.

I just want to report that I'm currently writing with my fc980c using tmk controller. I had to patch hasu's sources to enable legacy actionmap feature. I haven't updated to unimap yet and since all my other keyboards run with legacy actionmap I'll keep it this way for now. With actionmap in place I can finally use my keymap and switch fn/ctrl on fc980c. Thanks hasu!

I'll stop producing this controller when components in hand runs out. 30 pcs can be produced from the compoenents.

Updated firmware.  This change increase scan rate and disables debug print to accept fast key input .
Never got report from users but If you experience drop or transpose keys in fast typing try new firmware.

You can download from keymap editor or build from the latest source code.

Is there a way to reduce the delay for activating a modifier key when using dual-role (ACTION_MODS_TAP_KEY)? I currently have my left shift key activate caps lock on tap, and my caps lock key acting as Layer 1 key when pressed, backspace on tap.

I noticed there is a considerable delay when I try to activate shift or Layer 1. I type fairly quickly, so the delay is really messing up my speed.

I attached my hex file in case I might have done something wrong. I've only been using the keymap editor, still very new to TMK.

you can change the delay(200ms) with defining TAPPING_TERM in config.h. you have to build firmware form souurce codes.

When this doens't work you have to change codes under tmk_core/.
