module input - andreika-git/hellen-one GitHub Wiki

Module input has over-voltage protection, RC filters and pull-up/pull-downs

Part of analog input schematics like op-amp is actually on module-mcu which accepts 0-5v analog signals.

TL,DR: we have 16 analog inputs including pretty much mandatory VBatt which on stm32 goes into adc1/adc2, and adc3 is currently used only for knock.

Most common most consistent analog inputs (x7):

  • VBatt
  • MAP
  • CLT
  • IAT
  • First Primary TPS
  • First Pedal Position Sensor
  • o2

Simplest to use analog inputs above the most standard (x7)

  • map2
  • map3
  • o2s2
  • aux1/aux2/aux3/aux4

Also crank/cam could be ananlog (x2)

Res1 Res2 Res3 Sens1 Sens2 Sens3 Sens4 are currently only used for digital inputs and switches.

See implementation notes at https://github.com/rusefi/hellen154hyundai/issues/19

all inputs are +12v tolerant
