* Reduce PPS max to 20V to avoid instability Some PSU's cant actually run at 21V * Creating a rough draft of a "pre start check" concept * Newer alpine * Cleaning up MHP detection * Cleanup comments * PID: Run prestart based on ADC IRQ rather than times * MHP30: Far better startup for detecting tip gain * Newer alpine for github CI
