@knockretard - how did you time the readings between channel 1 and 2? Is it just fixed timing and alternating? I plan to use an interrupt based on ignition spark (understood crank position would be better), my concern is that if I alternate between channel 1 and channel 2 per ignition spark, I will ...

Hi, An educational query for myself, looking at the schematic, there are pulldown resistors on the SPI lines, but literature I have read insists that there is no requirement for pull-down/pull-up resistors on SPI lines. Only info I could find is regards mostly using pull-up for certain scenarios. T...
