Minor readability change for anybody keeping track.
Swapped the low and high name and inverted the "if >" result.
Purely a readability change. Explained by comment.

Currently looking to change

Code: Select all

void handleSparkPulse(uint8_t pin, unsigned long startTime, bool &activeFlag) {
  unsigned long now = micros();
  unsigned long elapsed = now - startTime;

  if (elapsed < currentOnDelaySpark) {
    digitalWrite(pin, LOW);
  } else if (elapsed < currentOnDelaySpark + currentOffDelaySpark) {
    digitalWrite(pin, HIGH);
  } else {
    digitalWrite(pin, LOW);
    activeFlag = false;
  }
}

So dwell can't be effected by rapid RPM change. Might be better to just use a higher dwell: figure out what kind of delta can be created by realistic extreme RPM change deltas over 15 degree increments, and increase main dwell value as needed. And then the same addition done to dwell gets subtracted from main spark table to keep the same spark timing.
EDIT: The "updated pulse handler" addressed this. AI wasn't helpful, had to do it manually. Fuel and spark get 2 functions each, with some extra flags to trigger thing right.

Should do for testing. 2 cylinder output board. Can test on a couple small engines I have. CB450 and 2 stroke snow blower.
Need to make the input board and add a cam sensor to the CB450 for a full sequential test.
I don't own anything V8.

MAP sensor is 5 volt. Pi Pico will die from that... Um, good enough.

Turns out I'm out of female headers, but, voltage divider, pull up resistors, and bias resistor in this mess.

Thanks for reminder. I have been using a 5v map sensor supply into the pico. Must fix it before it kills the pin. no smoke yet. Probably as it's mostly at 1-2v.

How much have you done?

Unclear on some details.
Just to be sure we're on the same page...
The power for the Pico is 5 volt, it has a regulator to drop that to 3.3. VBUS and VSYS if I remember right, are 5 volt input. You can remove a resistor or something to separate USB power I think.
Every other pin is not 5 volt capable.

... or not

Real tired of this shit.
