5d88272342 esp32/Makefile: Make sure that directory exists for sdkconfig.h. 2019-01-28 20:41:13 +11:00

3d49b157b8 esp32: Update to latest ESP IDF using sdkconfig and new ldgen procedure.
Configuration for the build is now specified using sdkconfig rather than
sdkconfig.h, which allows for much easier configuration with defaults from
the ESP IDF automatically applied.  sdkconfig.h is generated using the new
ESP IDF kconfig_new tool written in Python.  Custom configuration for a
particular ESP32 board can be specified via the make variable SDKCONFIG.

The esp32.common.ld file is also now generated using the standard ESP IDF
ldgen.py tool.

f59904f799 esp32/Makefile: Put all IDF compenents in .a libs to use IDF ld script.
When the ESP IDF builds a project it puts all separate components into
separate .a library archives.  And then the esp32.common.ld linker script
references these .a libraries by explicit name to put certain object files
in iRAM.

This patch does a similar thing for the custom build system used here,
putting all IDF .o's into their respective .a.  So a custom linker script
is no longer needed.

eb446ec227 esp32/Makefile: Use system provided math library rather than uPy one.
The ESP IDF system already provides a math library, and that one is likely
to be better tuned to the Xtensa architecture.  The IDF components are also
tested against its own math library, so best not to override it.  Using the
system provided library also allows to easily switch to double-precision
floating point by changing MICROPY_FLOAT_IMPL to MICROPY_FLOAT_IMPL_DOUBLE.

48d736f491 esp32: Update to latest ESP IDF.
Among other things, this requires putting bootloader object files in to
their relevant .a archive, so that they can be correctly referenced by the
ESP IDF's linker script.

a90124a9e2 esp32: Add support for building with external SPI RAM.
This patch adds support for building the firmware with external SPI RAM
enabled.  It is disabled by default because it adds overhead (due to
silicon workarounds) and reduces performance (because it's slower to have
bytecode and objects stored in external RAM).

To enable it, either use "make CONFIG_SPIRAM_SUPPORT=1", or add this line
to you custom makefile/GNUmakefile (before "include Makefile"):

    CONFIG_SPIRAM_SUPPORT = 1

When this option is enabled the MicroPython heap is automatically allocated
in external SPI RAM.

Thanks to Angus Gratton for help with the compiler and linker settings.

58ebeca6a9 drivers/bus: Pull out software SPI implementation to dedicated driver.
This patch takes the software SPI implementation from extmod/machine_spi.c
and moves it to a dedicated file in drivers/bus/softspi.c.  This allows the
SPI driver to be used independently of the uPy runtime, making it a more
general component.

bc08c884a2 esp32: Add new port to Espressif ESP32 SoC.
This commit is a combination of 216 commits from the initial stages of
development of this port, up to and including the point where the code was
moved to the ports/esp32 directory.  These commits were mostly concerned
with setting up the build system and getting a reliable port working with
basic features.  The following is a digest of the original commits in their
original order (most recent listed first), grouped where possible per
author.  The list is here to give credit for the work and provide some
level of traceability and accountability.  For the full history of
development please consult the original repository.

Odd Stråbø <oddstr13@openshell.no>
  esp32: Initial working implementation of machine.UART.

  Code lineage (as seen by previous commits): I copied the ESP8266 code,

  edited.  Total derivative work.

Andy Valencia <vandyswa@gmail.com>
  esp32: Add PWM support via machine.PWM class.

  Code lineage:
  I started by copying the esp8266 machine_pwm.c. I used information from the
  ESP32 Technical Reference Manual, the esp-idf documentation, and the SDK's
  sample ledc example code (but I did not copy that code, just studied it to
  understand the SDK's API for PWM). So aside from the code copied from the
  esp8266 PWM support, everything else you see is just new code I wrote.

  I wasn't an employee of anybody when I wrote it, and I wrote it with the
  understanding and intention that it's simply a derivative work of the
  existing micropython code. I freely and willingly contribute it to the
  project and intend that it not change the legal status of the micropython
  code base in any way, even if it is included in that base in whole or part.
