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

Switch to ets_delay_us but the PWM is still way too slow to be useful.

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

e37d5622fe tools: Add cpboard.py 
This is a variant of pyboard.py aimed at Circuit Python boards.
It can emulate pyboard.py enough so it works with tests/run-tests.

e580d22f4a Use the external crystal on SAMD21 again. 
Also, re-enable calibration storage for CircuitPlayground Express.
Tested with a 500hz PWMOut on Metro M0 with Saleae:
 * with crystal 500hz
 * with usb 500hz +- 0.1hz
 * without either 487hz += 0.1hz

SAMD51 is skipped due to DFLL errata and the fact it defaults to a
factory calibrated 48mhz that works fine for USB.

1c35dbfb5d Provide mp_errno_to_str even without uerrno 
We can provide a basic version of mp_errno_to_str even if the uerrno
module won't be provided.  Rather than looking errno names up in the
uerrno module's globals dict, we'll just rely on a simple mapping in the
function itself.
