ABC Original Leverless Arcade Stick [Assembly and Initial Setup Instructions]

This year's EVO was a huge success, with lots of new information coming out for various titles.
Whenever a large tournament is held, there is a lot of excitement surrounding arcade controllers and pads.
More and more people will be excited about the excitement of each event and want to try playing a new fighting game.

So, this time, the prototype leverless model I created previously has been made into a final version, so I would like to provide a review including everything from assembly to initial setup.

ABC Leverless Controller, Officially Adopted Version

*For more information on the prototype leverless controller, please see the article below.

This time too, the body is carved out of acrylic, the circuit board is made from a Raspberry Pi, and the original board uses keyboard key switches.
Additionally, adjustments have been made to the button positions since the previous version, making it easier for more people to use.
It also complies with CPT rules, and by default, neutral is supported when pressing up, down, left, and right simultaneously, eliminating the need for complicated settings.

First, here's a picture of the finished product

There are 10 attack buttons, one less than the 11 in the CPT.
It was created with the concept of "improving the usability of the special buttons rather than making it possible to use all 11 buttons."
The button on the far right next to the attack button is larger, and is designed with impact use in mind.
The special buttons use smoked keycaps for easy visual identification.
I think this is an installation that allows for a wide range of operations depending on how you set it up.
For example, adding analog stick input...

Planned to be released as a finished product and kit version

We plan to sell ABC-less controllers at Booth, but we would like to keep the price low so that they are easy to purchase.
We sell the finished version, but we are also considering developing a leverless kit that includes all parts (except the cable).
If you have basic soldering skills, it should take less than 30 minutes to complete.
Below are the contents of the ABC Leverless Controller

・Top plate (1 piece)

・Middle plate (2 pieces)

・Bottom plate (1 piece)

・Raspberry Pi

·substrate

・Key switches (14)

・Switch covers (14 pieces)

- Tactile switches (3 pieces)

・OLED (1 piece)

- Mounting screws (8 pieces)

Has become.

Attach various switches to the blue circuit board and sandwich it between acrylic plates to complete the project.
There aren't many soldering points, so you just need to be careful when attaching the Raspberry Pi.
The Raspberry Pi uses a Type C USB, so the chances of the connector breaking are very low.
If you want to use it on a consumer device, you will need to prepare a separate converter.

Assembling the ABC Leverless Controller

There is also a video explaining how to assemble it.

First, install the circuit board and Raspberry Pi
The Raspberry Pi has 40 terminals and is quite delicate, so you need to be careful when working with it.

Attach the Raspberry Pi to the surface of the board.
Using masking tape will make the job easier.

Be careful not to confuse the front and back.

Next, install the OLED.

Attach the OLED so that it passes through the terminal hole from the surface, and then solder it.

Next is to install the tactile switch.
This tactile switch functions as an option button and a capture button.

Installing the key switch.
There are a lot of pins and the gaps between them are small, so you only need to use a small amount of solder...
It will be a little easier if you first insert all the key switches and then work on it.

Once all the electronic parts are installed, the next step is to write a program to operate the arcade controller onto the Raspberry Pi.

ABC Leverless Controller Initial Setup

Once assembly is complete, write the program for the arcade stick onto the Raspberry Pi.
The program is available online, so first download it for Raspberry Pi.
GP-2040 download site
Once you go to the download site, download the file surrounded by a red frame.

Next, drag and drop the downloaded file onto the Raspberry Pi. When connecting to your PC, press and hold the white switch on the Raspberry Pi while connecting the arcade stick to your PC.
Please prepare a cable that has one type C end.

If you connect the arcade stick while holding down the button, the folder will automatically open, so all you have to do is move the downloaded file there.
After moving the GP-2040 files by dragging and dropping them, you can simply reconnect the cable and use it as an arcade stick.

Button settings

I also use the PC for button settings.
In the initial state, connect to the PC while pressing the switch that corresponds to the SELECT button.

Then, open an internet browser on your PC and enter the following address in the URL field:
http://192.168.7.1/
This address is also printed on the circuit board.

Once the connection is complete, the following page will open.

To configure the buttons, select "Pin Mapping" under "Configuration" in the top menu.

Use the pull-down menu in Pin Mapping to set the buttons.
It may be confusing at first because it is not the PS-style circle, triangle, or ABXY notation of Xinput, but if you use Pin viewer to set it up, it shouldn't be difficult.
If you want to set it up even more easily, you can set it up the same way as a basic arcade stick by using the settings shown in the image below.

If you set it up the same way as in the image, the button layout will be as shown in the image below.

SOCD Cleaner

The initial setting is neutral for simultaneous left, right, up, and down input.
If you want to change it, go to the Settings page of the above tab and change the SOCD Cleaning Mode.
You can change the order to last priority or first priority.

Additionally, you can change the default connection method, analog stick mode, and other settings, so try to find a setting that is easy for you to use.

A leverless controller that prioritizes ease of use and is easy to carry

I have purchased and used many arcade controllers so far, and have tried various things, such as changing the buttons.
I don't want to think about how much I spent on just the arcade controller and parts, but I couldn't see any end in sight to my arcade controller quest.
By pursuing something that is easy for me to use, I feel like I've been able to fill the gap that many people felt was missing.
The ABC Leverless Controller will be available for sale at Booth.
There are two types available: a finished product and a kit, so if you're confident in your crafting skills, be sure to get your hands on one.
