Apparently there is a CircuitPython Guide for ItsyBitsy M0 too...
It just contain "kattni' in the name and I don't know if this is finished and similar to the other guide.

Scott Shawcroft 2fbab8067a Prevent freezing USB during high frequency PulseIn. 
We now track the last time the background task ran and bail on the
PulseIn if it starves the background work. In practice, this
happens after the numbers from pulsein are no longer accurate.

This also adjusts interrupt priorities so most are the lowest level
except for the tick and USB interrupts.

Fixes #516 and #876

Merge pull request #905 from jepler/main-stack-usage 
main: move code pertaining to boot.py out of line
 2018-06-06 09:24:51 -04:00
Jeff Epler 654591e11f main: move code pertaining to boot.py out of line 
.. this reduces stack usage in main() substantially, because
the 512 byte stack allocation will only exist during the new run_boot_py
function's duration.

Closes: #904

Merge pull request #903 from jepler/stack-overflow-crash 
main: Explicitly set the stack top based on _estack
 2018-06-05 22:05:13 -07:00
Jeff Epler a4e06bd998 main: Explicitly set the stack top based on _estack 
.. setting it based on the ad-hoc stack pointer calculation of
mp_stack_ctrl_init() meant that the stack used above main() counts
against the 1KiB safety factor that the mp_stack_set_limit call tries
to establish.  It turns out, at least on M4, that over half of the
safety factor is used up by stack-above-main()!

In the case of the basics/gen_stack_overflow.py test,
which blows the stack on purpose, it turns out that gc would be called
while handling the "maximum recursion depth exceeded" error, and this
needed more stack than was left.

Closes: #900
