test_problem2_song_am.py — 问题2回归：曲目 LED 引导不得把 Am 改成 AM7
|
||
|
||
场景复现(修复前):
|
||
曲目模式 UI 显示 6m(Am)，App 发 LED 引导帧 F0 60 04 05 02 02 F7
|
||
(协议文档示例，p3=0x02=大七)，BL_Set_led 把 VI 中间键(17)写成 AM7，
|
||
拨弦发出 E2 A2 E3 G#3 C#4 E4 而非 Am 的 E2 A2 E3 A3 C4 E4。
|
||
|
||
本脚本(等效 MIDI-OX 抓包):
|
||
RTT `string N` 与硅胶弦同一 SendNoteOn 路径，ACK 即线上实际音符。
|
||
1) 映射页路径设键17=Am(0x08) → chord key 17 → string 6..1 抓音符
|
||
2) BLE 发 LED 帧 04 05 02 02(模拟曲目 6m 引导)
|
||
3) 重新 chord key 17 → string 6..1 再抓，必须仍是 Am
|
||
4) 02 01 读回键17必须仍是 0x08
