Description
As of version 1.2.1 of the library, ATmega32u4-based boards are defined to use Timer1
raher than Timer3
. This configuration conflicts with millis()
and micros()
functions. While not too difficult to change, it does make the library more difficult to use in educational settings (we're a robotics/programming school for kids). If possible, could Timer1
be changed to Timer3
for these devices? The specific device we are using is an Adafruit ItsyBitsy 5V.
It would be no issue to submit a PR, of course, provided there isn't a strong reason to keep it as Timer1
, as technically this would be a breaking change (although it is likely 32u4 users of this library make this modification anyhow, as millis()
and micros()
are useful functions...). Likewise, if there is a workaround that is fairly straightforward and does not require modification of the library that we are not aware of, please let us know.
It is worthwhile mentioning that we have seen other examples of this choice of Timer1
instead of Timer3
being an issue on 32u4 boards, most notably from Pololu Robotics and Electronics: https://www.pololu.com/docs/0J57/8.b
