Summary of change:
Trigger related '''subpage of MembersPage/StuFrench''' Apparently spent weeks (or months), and generated [http://vems.hu/www.vems.co.uk/forum/index.php?topic=535.0 1000 lines at the VEMS UK forum] of text (totally unsuitable for good overview). Fortunately the trigger setup and measurements are starting to shape here now, good. (wiring is still confusing though). At least investigation can start this way. It seems there was a '''long chain of useless experiments with known trashed config. Upload known good config before continuing''' any further experiments. ---- '''Primary trigger HALL 60-2''' At TDC tooth 15. (tooth0 is the tooth selected edge after missing tooth, tooth10 is 6 crankdeg later, etc...) '''verify the internal pullup resistor''' - not needed now * temporarily connect a 1k resistor between EC36/27 and GND ** '''measure voltage.''' (above 1V for strong pullup - preferred for HALL; below 500mV for weak pullup - preferred for VR). ---- '''HALL voltage verified OK''' (DVM and scope): measure how the '''EC36/27 voltage''' changes, turning the engine over by hand - it seems perfect: * 3.5V * pulled consistently down to 0.05V at each tooth. ---- '''Secondary trigger HALL''' Hall-effect sensor on camshaft for camsync (1-window trigger wheel) * My Secondary trigger is disabled as I'm running the primary only secondary_trigger=02
