However, the company provides instructions and tools to do so.
Basically, you need to be a computer programer to do so.
Here's an excerpt from the company's site (as of 2017-11-02):
Q: How can I customize the firmware?
Take the following steps to customize the firmware for your NISSE:
Download and install the MPLAB X IDE and MPLAB XC8 Compiler from the Microchip web site. They support Windows, Mac, and Linux. Note the current NISSE firmware is built with XC8 v1.34 in the free mode.
Download the NISSE firmware from GitHub ▶.
Open the project firmware/third_party/mla_v2013_12_20/apps/usb/device/hid_keyboard/firmware/MPLAB.X from MPLAB X IDE. Now you're ready to build your firmware.
I have an Esrille NISSE and love it. I've been using it full time (6-10 hours a day, 5-6 days a week) since .
Side note: I believe I was actually the first person in the US to order one. It was before they were able to ship assembled boards internationally, so I ordered it as a kit and assembled it myself. I forget where I first saw it — maybe Xah Lee's blog - but the design was immediately appealing to me.
The other ergo boards I've used extensively are the Ergodox and Truly Ergonomic Keyboard. I like them all but the Esrille has been the best fit by a wide margin.
The things I like about all three are:
Columnar layout
More natural hand position
Moving what would otherwise be pinky keys to instead be thumb or index finger keys
Mechanical switches
What I like about the Esrille above the other two:
More thumb keys than the TEK
More usable (for me) thumb keys than the Ergodox
Smart column spacing. I find it very comfortable and natural
Built-in tenting. You can obviously tent an Ergodox, but the Esrille's shape works great for me as is, and I like not needing another piece. Also, I was surprised how expensive it is to have a tent printed, at least from the places I cheked.
It looks great (and I say that as someone who normally my electronics and peripherals to be matte black)
Subjectively, I can tell you the Esrille is definitely the most comfortable for me. I used to experience some level of discomfort 1-3 out of most weeks, despite fairly good technique, regular exercise, breaks every couple hours, etc. I honestly don't remember the last time I experienced any discomfort typing since switching to the Esrille.
This is less important, since it's something you can always change, but I'll also mention that I've been very happy with the default layout on the Esrille, including the function layer. I fully expected to reconfigure things, just because I usually would, but in practice there hasn't been anything I've wanted to mess with.
As I'm sure you can tell, I'm a big fan, and would be very comfortable recommending it :)
Let me know if you have any questions about it — I'll be happy to answer any I can.
I tried to take a photo side by side NISSE as “Easy Keyboard” keyboard of genuine NEC-made M-System for which you are introduced from time to time as an array for Japanese input. Easy is like those made in PC-9801 for the 1995 keyboard

. As a standard, it was made in 1998 after this model “Ergo Fit Keyboard”

seems to be M-System keyboard last. We are right to be “we expect to sell 20,000 units in one year”, those that are actually used even now It seems there.
At the stage of prototype had been made in the design of the fan-shaped as NISSE [3]

things, “Based on the prototype, it is working to improve from the point of view as industrial products” Te, M expression The comparison ergonomic elements it is the product initially, it seems went to calm with less ergonomic elements such as photo gradually as [4]

PC-8801-KI design of grid-like leaving strongly subject. As a stream those of ergonomic elements packed original have converged only TK-1 in 1991 as a standard also TRON keyboard, towards the μTRON keyboard that became less of ergonomic elements and to them being sold now It does not may have been felt are similar.
NISSE Although I wrote earlier that it has been made to the influence book of Ken Okuyama's called “the art of making” two hundred individuals “without also one million units even one” [5]
[http://www.amazon.co.jp/exec/obidos/asin/4569809529/ ]
, meaning of the word “the art of making” two hundred individual “” is again Looking “expects to sell 20,000 units in one year” from that was a product of the end of the M-System keyboard you have already converged I think it also comes to.
