The -ansi flag is used for C dialect selection and it is equivalent to -std=c90.
Because it goes right before -std=gnu99 it is ignored as for conflicting flags
GCC always uses the last one.
All arguments to pin.irq are converted from keyword-only to positional, and
can still be specified by keyword so it's a backwards compatible change.
The default value for the "trigger" arg is changed from 0 (no trigger)
to rising+falling edge.
Allows to iterate over the following without allocating on the heap:
- tuple
- list
- string, bytes
- bytearray, array
- dict (not dict.keys, dict.values, dict.items)
- set, frozenset
Allows to call the following without heap memory:
- all, any, min, max, sum
TODO: still need to allocate stack memory in bytecode for iter_buf.
This effectively reverts the change that introduced this new constant.
The reason is so that users do not need to rebuild the filesystem on
their modules when upgrading the firmware.
Users can change RESERVED_SECS by hand if they need the feature, and in
future firmware it may default to a non-zero value.
This code is no longer pertinent for some time - since switchover to
SDK2.0, there must be correct flash size set for bootloader, or there's
a risk of flash data corruption. And indeed, the correct flash size is
by default auto-detected by esptool.py 1.2.
Starting at esp.flash_user_start(), the reserved sectors are for general
purpose use, for example for native code generation. There is currently
one sector reserved as such.
This patch allows esp8266 to use @micropython.native and
@micropython.viper function decorators. By default the executable machine
code is written to the space at the end of the iram1 region. The user can
call esp.set_native_code_location() to make the code go to flash instead.
The 512k build recently overflowed because of the newly-enabled uselect
module. uselect is arguable more important than framebuf for small
devices so we disable framebuf to keep the 512k build within its limit.
So long as a port defines relevant mp_hal_pin_xxx functions (and delay) it
can make use of this software SPI class without the need for additional
code.
If a port defines MICROPY_READER_POSIX or MICROPY_READER_FATFS then
lexer.c now provides an implementation of mp_lexer_new_from_file using
the mp_reader_new_file function.
