まさか3周年新規(レベル69, ログイン51日目)の俺よりダイケツのスコア低いカンスト勢はおらんよな？^^^^^^^^^^^^^^^^
ブルアカ筋あったまりすぎだろ！
とかいって一人でキャッキャしてたら弊サークルにレベル85の3周年新規とかいう化物が入ってきた. 少なくとも2倍期間中は300割までしてるよなこれ. やばすぎる. 俺がもう数日早く始めて最初からブルーアーカイブに真剣だったとしてもレベル75くらいまでしかいかないぞ.
重装甲はサークルにドヨコ持ってる人おらんかったからミカ借りて, 残りを自前ミカとその他ゾンアタでなんとかクリアした. ミカと水着ホシノはタンクでもないのに何故かミサイルも砂塵も耐えていくから湯ドカと併せて落ちずに最後まで殴れて400k程度は削れた.
セレチケはヒマリに使いました. EXとINSでレアコインの枚数倍も違うし, 獲得ポイント報酬もあるからすり抜け杞憂して温存するよりここで使った方がいいと判断した.

最近8k HzなMX PCBちょくちょく見るね.まあ1k Hz, chord splitなQMKで全然問題ないってRTINGSにばらされてるんですけどね.
[BUILD] Nyan Keys - An FPGA based USB 2.0 HS 8000hz Open Source PCB Design
FPGA
The FPGA at the heart of Nyan Keys is used to handle the debounce of each key and high speed serialization of that data so that it can be pushed out over USB. Each key gets it's own timer core. As such all keys are parallel and do not require any diode and such! This also eliminates the need to scan a matrix since everything is happening in parallel.
The switch will arm instantly, then the state of the switch can't change until the debounce count is complete. After the count reaches the max value in [debounce time] the switch can then send over a new state instantly. What this means simply is that unless you are able to press keys at under 1ms you will not have any debounce time since the key would arm and release instantly.
The communication to the MCU that is the USB device is done via a DMA based SPI channel where 9 bytes are requested from the board at a time to represent each of the 61 keys as a binary 0 or 1. The current speed of the board can run the SPI bus at 12.5Mhz and Nyan OS can fetch a full state around 80k times a second. Which is 10x faster than what the USB bus can generate interrupts at. Using the FPGA to handle all of the debouncing instead of the MCU leaves the MCU free to send packets over USB without having to wait for any scanning to complete. This also leads into the fact that each key starts it's count instantly instead of waiting for the MCU to hit that key in it's scan pattern.
すごい(小並感).
ただこのやり方だとMulti Layout Compatibleなやつは作れないよな. 基板設計さっぱりわからんけど多分.
