How To Write Firmware

Tools

PC (Windows以外での動作確認はしていません)
WCH-Link E (秋月で750円)

Connection

x : None (何もつながない)
- : 3.3V (シルク印刷の都合上"I"に見えてしまうので注意)
G : GND
D : DIO
C : CLK （x～Cまでの4ピンが四角で囲まれているが特に意味はないので注意）

LED blink sample

こちらのブログを参考にサンプルのプロジェクトをビルドし、実行する。

LEDが緑→水色→青と点滅すればOK。

Hardware Issues

LEDmatrixに対し電源が供給されていません（配線ミス）。電源線を追加する必要があります

以下のようにボタンの右上(SW2 2pin)とR55のどちらかのピン（どちらでも同じ）をスズメッキ線などで接続してください。
なお、この修正方法では、LEDドライバおよびLEDに3.3Vが供給されます。本来は4.5Vを供給する予定でしたが、3.3Vでも機能します。

SELECT ボタンはプログラム内で入力ボタンとして使用できません。

このボタンはBOOTセレクトボタンとしてのみ機能します。

Do not populateに指定されている部品類もあやまって実装されています。

本来非実装にすべき部品類がBOMの誤りにより実装されてしまっています。

シルクの問題 : シリアル通信のTとRの表記がミスリードです。

MCUにとってのTXにR、RXにTと書かれています。

シルクの問題 : WCH Link-Eを接続すべき端子のうち、3.3V端子に"I"と見えるシルクがあります。

これは+と刻印したところ、ほかのシルクと被ってしまったために生じています。

現状動作確認が終了していません。

後悔＆将来やりたいこと

以下の内容や不可解な設計の大半はスケジュールによるものです。（マイコン決定から発注まで24時間以内）
USBからBootできない
- 発注直前でマイコンの型番変更が必要になり、そこまでケアできなかった
高すぎる
- emmc載せると基板費用、実装費用含めて価格が倍増する
新規コンポーネント
- スピーカ
- 加速度センサ
- スーパーキャパシタ
- IMU
- TOF

Questions

How big is the Type c card lexxpluss 2023 PCB?

It measures 89 × 57 mm and has 4 copper layers, 0.78 mm thick.

What parts does the Type c card lexxpluss 2023 use?

316 parts, built around the FT231XQ-R, IS31FL3731-QFLS2-TR, TPS65987DDHRSHR and USB2241I-AEZG-06. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the Type c card lexxpluss 2023 KiCad files?

From the shujima/type-c-card repository on GitHub, at the commit this page was made from: the board is hardware/sample/type-c-card_lexxpluss_2023/type-c-card_lexxpluss_2023.kicad_pcb and its schematic hardware/sample/type-c-card_lexxpluss_2023/type-c-card_lexxpluss_2023.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Type c card lexxpluss 2023 design in my own project?

Its repository states no licence, so its author keeps all rights: ask shujima before reusing the design.
