Ich habe mal versucht, den Code für Teensy 4.1 zu compilieren.
Leider bekomme ich Fehlermeldungen. Da ich mich noch nicht so gut auskenne, denke ich, dass die Bibliothek noch nicht richtig für die 4.1er Version angepasst ist. Stimmt das?
Was kann ich da tun? (Bitte sagt jetzt nicht anpassen, denn das würde mich noch überfordern)
Die IDE schlägt ja einen anderen Namen vor, das hilft aber leider auch nicht weiter.

/* The pulses for Mclk and ADCtrigger are made with PWM outputs.
* On teensy 3.2 there are 3 timers for PWM:
* FTM0 can drive pins 5, 6, 9, 10, 20, 21, 22, 23
* FTM1 3, 4
* FTM2 25, 32
* all pins of one timmer have the same frequency,
* so three different frequencies are possible.
* We can set the
* resolution with analogWriteResolution(bits),
* frequency with analogWriteFrequency(pin, frequency) and
* dutycycle with analogWrite(pin, value)
* Depending on the resolution we can choose different ranges of
* frequency, the lower the resolution the higher the possible frequency.
* e.g. 5 bits up to 1,5 MHz, 4 bits up to 3 MHz. (f_CPU = 96 MHz)
* The dutycycle must be half of 2^resolution (16 for 5 bits, 8 for 4 bits)
* to get a square wave.
