Me Here 8f662598e4 PM_K-1 hardware: MIDI block (DNP) -- opto IN + buffered OUT/THRU ... circuits/midi.py, a do-not-populate option (USB-MIDI is the default). H11L1 opto-isolated IN (breaks the MIDI ground loop), 74LVC14-buffered OUT (TX through two inverters) and THRU (re-buffered IN). Connector is a face choice; core exposes the loop nets MIDI_IN/OUT/THRU_A/B plus MIDI_TX/RX to the RP2350 UART. ERC 0 errors; netlist 0 errors. CONFIRM: H11L1 pinout (standard; datasheet fetch timed out) + 3.3V-MIDI series-R values. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>		2026-05-30 23:28:59 -05:00
