Before I contact support I have a question about the extra ignition outputs on the micromodl2.2 board. The iGN1&2 outputs are logic level driven straight off the board with a 100kohm pull down resistor and voltage clamp. I'm using these logic level outputs to drive an N channel IGBT ignition driver. So in tuner studio I'll be driving the ignition outputs high. However I'm also going to be using the additional aLED and wLED outputs to drive my other 2 coils for 4 cylinder sequential spark.
The problem is aLED and wLED are not logic level outputs, but come off the on board mosfet drivers, so active high is actually a path to ground, so opposite the IGN1&2 pins.
My question is, does the code account for this and invert the aLED and wLED outputs or are the processor pins all configured the same, active high. It's no big deal to use a logic inverter and some pull up resistors, just need to know before I go any further.
