Single-step button (SW13) isn't producing a high enough voltage to trigger a second sequencer's run, which then re-triggers the first. More feature ideas: Trigger out - could be done with a 7-segment display with a capacitor / resistor pair, see Fireball's hard sync to schematic, laid out PCB with on-board components c6741b48f0 More random files c6741b48f0ef8a6e69ecbca1a47bc4f4b481e2a3 Notes from debugging Notes from MK's PCB livestream # Format documentation: https://kicad.org/help/file-formats/ # Temporary files *.000 *.bak *.bck *.zip *.DS_Store *~ .gitignore-extra *.dsn *.kicad_pcb-bak *.kicad_sch-bak *-backups *.kicad_prl *.sch-bak *~ _autosave-* *.tmp *-save.pro *-save.kicad_pcb fp-info-cache # Netlist files (exported from Eeschema *.csv *.lck ########################## # Additional ignored # KiCad backups folders *-backups # Compressed files *.zip # Mac stuff *.DS_Store # Emacs temps *~ \#* # LTSpice Simulations/*.log Simulations/*.raw Simulations/*.txt Copper Layer Stackup: ============================================================= L1 : F.Cu front L2 : B.Cu back Drill file 'precadsr-panel.drl' contains plated through holes: ============================================================= T1 3.200mm 0.1260" (4 holes) (with 4 slots T2 5.000mm 0.1969" (1 hole) T3 7.000mm 0.2756" (6 holes) T4 10.000mm 0.3937" (4 holes T5 15.200mm 0.5984" (1 hole) T3 7.000mm 0.2756" (6 holes) T4 10.000mm 0.3937" (4 holes) (with 4 slots T2 5.000mm 0.1969" (1 hole) T3 7.000mm 0.2756" (6 holes T4 10.000mm 0.3937" (4 holes T5 15.200mm 0.5984" (1 hole) Total plated holes count 16 Not plated through holes: =============================================================
