c80e1908c5 Added Trinket to README.md (#344) 
Added Trinket to README.md

Despite shipping with CircuitPython pre-installed, the Trinket M0 is
absent from the README.md file. This fixes that issue.

285ac58532 stm32/modnwwiznet5k: Increase SPI bus speed to 42MHz. 
The W5200 and W5500 can support up to 80MHz so 42MHz (the maximum the
pyboard can do in its standard configuration) should be safe.

Tested to give around 1050000 kbytes/sec TCP download speed on a W5500,
which is about 10% more than with the previous SPI speed of 21MHz.

c6a15f76ad esp8266: add neopixel_write - remove neopixel.py (#339) 
For ESP8266, remove frozen module neopixel.py and add neopixel_write to mpconfigport.h. Use  [Adafruit_CircuitPython_Neopixel/neopixel.py](https://github.com/adafruit/Adafruit_CircuitPython_NeoPixel) instead.

6c7d35c40c esp8266: Correct SPI functionality when write_value is provided. 
It used to introduce extra clocks to the bus rather than changing the
value output.

This fixes SD cards.

274fff4226 Use internal libm for all atmel-samd boards. 2017-10-16 12:20:33 -07:00
Dan Halbert
dbd3f15168 1. Use lib/libm for small (non-Express builds) to gain back a lot of flash space. 
2. Add flag INTERNAL_LIBM to mpconfigboard.mk files to signal using lib/libm.
3. Fix floating-point warnings in lib/libm
4. Turn off -finline-limit, no longer needed due to 1.
5. Add explicit flags for SPI_FLASH_FILESYSTEM and INTERNAL_FLASH_FILESYSTEM
to mpconfigboard.mk files, so they don't need to know the name of the .c file
that implements those. Makefile takes care of checking the flags and including
the right files.

e36821a766 stm32/modnwwiznet5k: Add support for W5500 Ethernet chip. 
Which Wiznet chip to use is a compile-time option: MICROPY_PY_WIZNET5K
should be set to either 5200 or 5500 to support either one of these
Ethernet chips.  The driver is called network.WIZNET5K in both cases.

Note that this commit introduces a breaking-change at the build level
because previously the valid values for MICROPY_PY_WIZNET5K were 0 and 1
but now they are 0, 5200 and 5500.

c0ea91bc89 drivers/wiznet5k: Get low-level W5500 driver working. 
This patch implements the basic SPI read/write functions for the W5500
chip.  It also allows _WIZCHIP_ to be configured externally to select the
specific Wiznet chip.

37282f8fc1 extmod/uos_dupterm: Update uos.dupterm() and helper funcs to have index. 
The uos.dupterm() signature and behaviour is updated to reflect the latest
enhancements in the docs.  It has minor backwards incompatibility in that
it no longer accepts zero arguments.

The dupterm_rx helper function is moved from esp8266 to extmod and
generalised to support multiple dupterm slots.

A port can specify multiple slots by defining the MICROPY_PY_OS_DUPTERM
config macro to an integer, being the number of slots it wants to have;
0 means to disable the dupterm feature altogether.

The unix and esp8266 ports are updated to work with the new interface and
are otherwise unchanged with respect to functionality.

80654779e1 atmel-samd: Add support for internal filesystems. (#311) 
* atmel-samd: Add support for internal filesystems.

This allows us to re-enable `os`. `random` is also enabled because
it solely depends on `os`.

Fixes #266. Its also a pre-requisite for #260.

* atmel-samd: Update SAMD51 linker script comments and MICROPY_MAX_STACK_USAGE enabling.
