f7facf73f1 nrf: Add micro:bit filesystem.
* ports/nrf: Add micro:bit filesystem.

This filesystem has been copied from BBC micro:bit sources [1] and
modified to work with the nRF5x port.

[1]: https://github.com/bbcmicrobit/micropython/blob/master/source/microbit/filesystem.c

* ports/nrf/modules/uos: Make listdir() and ilistdir() consistent.

This removes the optional direcotry paramter from ilistdir(). This is
not consistent with VFS, but makes more sense when using only the
microbit filesystem.

Saves about 100 bytes.

* ports/nrf/modules/uos: Add code size comment.

fcc1568546 nrf/boards: Update linker scripts.
* Remove FLASH_ISR and merge .isr_vector into FLASH_TEXT. This saves
    some code space, especially on nRF52 devices.
  * Reserve space for nonvolatile storage of data. This is the place for
    a filesystem (to be added).

    ports/nrf: Moving nrf51/52 port to new ports directory
    nrf: Aligning with upstream the use of nlr_raise(mp_obj_new_exception_msg(&mp_type_ValueError, ...)

Glenn Ruben Bakke <glennbakke@gmail.com>
    nrf/modules/random: Backport of microbit random number generator module

    Backport of micro:bit random module.
    Plugged into the port as a general random module for all nrf51/nrf52 targets. Works both with and without Bluetooth LE stack enabled.

    Behavioral change: seed() method has been removed, as the use of RNG peripheral generates true random sequences and not pseudo-random sequences.

Glenn Ruben Bakke <glennbakke@gmail.com>
    nrf/hal/rng: Adding HAL driver for accessing RNG peripheral

    The driver also takes care of calling the Bluetooth LE stack for random values if the stack is enabled. The reason for this is that the Bluetooth LE stack take ownership of the NRF_RNG when enabled. Tolerate to enable/disable on the fly, and will choose to use direct access to the peripheral if Bluetooth LE stack is disabled or not compiled in at all.

    Driver has been included in the top Makefile, and will not be compiled in unless nrf51_hal_conf.h/nrf52_hal_conf.h defines HAL_RNG_MODULE_ENABLED (1).

    nrf/boards: Adding Arduino Primo board support (#88)

    * nrf: Adding Arduino Primo board support
    * nrf: Adding arduino_primo to target boards table in readme.md
    * nrf/boards: Activating pyb.LED module for arduino_primo board.
    * nrf/boards: Removing define not needed for arduino_primo

    Updating arduino_primo board mpconfigboard.h. Removing a define
    that was wrongly named. Instead of renaming it, it was removed as
    it was never used.

Glenn Ruben Bakke <glennbakke@gmail.com>
    nrf: Add support for floating point on nrf52 targets.

    Duplicating pattern for detecting location of libm, libc and libgcc
    from teensy port. Activating MICROPY_FLOAT_IMPL (FLOAT) for nrf52 targets
    and adding libs into the compile. For nrf51 targets it is still set to
    NONE as code grows to much (about 30k).

    Some numbers on flash use if MICROPY_FLOAT_IMPL is set to
    MICROPY_FLOAT_IMPL_FLOAT and math libraries are enabled (lgcc, lc, lm).

    nrf5/modules/music: Correct parameter checking of pin argument to deside whether to use MUSIC_PIN define or throw an error. If MUSIC_PIN define is configured the pin argument to music module play() can be elided.
    nrf5/modules/machine: Update timer init to set default IRQ priority before initializing Timer instance.
    nrf5/hal/timer: Update timer hal to use value provided in init to configure the irq_priority.
    nrf5/modules/machine: Reserving timer0 instance for bluetooth if compiled in. Leaving timer1 and timer2 for application. Note that music module soft-pwm will also occupy timer1 if enabled.
    nrf5/modules/machine: Updating timer module to use new hal. Adding new parameters to the init to set period, mode and callback.
    nrf5/hal/timer: Implementing hal_timer to 1us prescaler. Multiplier inside to get to millisecond resolution. Callback must be registered before starting a timer.

    Adding a README for the nRF5 port

Glenn Ruben Bakke <glennbakke@gmail.com>
    nrf5/examples: Updating documentation in SDCard module example. Correcting typo and adding SD card wireing documentation for direct SPI connection.
    nrf5/modules/pin: Adding on() and off() methods to Pin object to be forward compatible with upstream master. Legacy high() and low() methods are kept.
    nrf5/modules/spi: Remove pyb abstraction from SPI module, as there was a bug in transfer of bytes due to casting errors. The update removes the pyb_spi_obj_t wrapper going directly on the machine_hard_spi_obj_t as base for machine SPI objects. SDCard mounting is also tested.
    nrf5/drivers/bluetooth: Enable ubluepy central by default if running nrf52/s132 bluetooth stack. Maturity of the module is pretty OK now.
    nrf5/boards/feather52: Updating pins.csv for the feather52 board.
    nrf5/boards/feather52: Updating LED pull to low.
    nrf5/boards/feather52: Update SPI pinout.
    nrf5/main: Move initializaton of modmusic to the module itself. Upon init of the module, the hardware, pwm and ticker will be started. Could be moved back to main if pwm or ticker should be shared among more modules and have to be initialized more global.
    nrf5/modules/machine/timer: If timer is used in combination with SOFT_PWM (implicitly use of ticker.c) guard the Timer1 instance from being instantiated trough python timer module. Also disable implementation of the HAL IRQ handler which is for now explicitly implemented in ticker.c for Timer1.
    nrf5/modules/music: Update ticker and modmusic to share global ticks counter as a volatile variable. Use Timer1 hardware peripheral instead of instance 0. Timer0 is not free if used in combination with a bluetooth stack. Update IRQ priority to levels that are compatible in use with a bluetooth stack for both nrf51 and nrf52. Apply nrf51 PAN fixes for Timer1 instead of original Timer0.
    nrf5/drivers/bluetooth: Updating bluetooth driver to initialize nrf_nvic_state_t struct during declaration of the global variable instead of explicit memset.
    nrf5/hal/irq: Adding wrappers for handling nvic calls when Bluetooth LE stack is enabled.
    nrf5/modules/machine: Updating IRQ levels in SPI with IRQ priorities compatible with Bluetooth stacks.
    nrf5/device: Remove old startup files in asm, which has now been replaced with c-implementation.
    nrf5: Update Makefile to add c-implementation of startup scripts instead of the .s files.
    nrf5/device: Adding startup files in .c to replace current asm versions.
    nrf5/examples: Tuning Bluetooth LE example controller python script after testing out the example live. Motor speed of 100 was not enought to lift the airplane. Also turning was hard without setting higher angle values. The new values are just guessed values. However, the flying experience was good.
    nrf5/hal/irq: Adding include of nrf_nvic.h if s132 bluetooth stack is used to resolve IRQ function wrappers on newer bluetooth stacks.
    nrf5/drivers/ticker: Removing unused code.
    nrf5/examples: Adding music example. Only working if bluetooth stack is not enabled.
    nrf5/boards/microbit: Disable music and softPWM as there are some issues with the ticker.
    nrf5: Adding -fstack-usage flag to gcc CFLAGS to be able to trace stack usage on modules.
    nrf5/drivers/ticker: Removing LowPriority callback from nrf51 as there is only one SoftwareIRQ free if bluetooth stack is enabled. Also setting new IRQ priority on SlowTicker to 3 instead of 2, to interleave with bluetooth stack if needed. Updating all NVIC calls to use hal_irq.h defined static inlines instead of direct access.
    nrf5/hal/irq: Adding IRQ wrappers if Bluetooth Stack is present.
    nrf5: Facilitate option to configure away the modble if needed. Enabled if MICROPY_PY_BLE config is enabled in bluetooth_conf.h.
    nrf5/boards/microbit: Enable music module by default. However, timer and rtc module has to be disabled. Bluetooth support broken. Optimization needed.
    nrf5/modules/machine: Quickfix. Update timer object to not allow instanciation of Timer(0) if SOFT_PWM is enabled by board.
    nrf5/hal/timer: Quickfix. Disable IRQ handler if SOFT_PWM is configured to be enabled. Ticker driver has in current driver a seperate IRQ handler for this timer instance.
    nrf5/drivers/ticker: Add compile config guard in ticker.c to only include the driver if SOFT_PWM is configured in by board.
    nrf5/drivers/softpwm: Renaming pwm_init to softpwm_init to not collide on symbol name with pwm_init in nrf52 machine PWM object.
    nrf5: Add modmusic QSTR definition of notes to qstrdefsport.h.
    nrf5: Update Makefile to include ticker.c and renamed softpwm. Updating also include paths to include modules/music and drivers/.
    nrf5: Adding include of modmusic.h in main.c.
    nrf5: Call microbit_music_init0() if enabled in main.c.
    nrf5/modules/music: Expose public init function for music module.
    nrf5/modules/music: Update modmusic to use updated includes. Add extern ticks. Add function which implements initialization of pwm and ticker, register ticker callback, and start the pwm and ticker. This corresponds to microbit port main.cpp init.
    nrf5/drivers/softpwm: Enable use of ticker in softpwm driver.
    nrf5/drivers/ticker: Adding ticker.c/.h from microbit port.
    nrf5/drivers/pwm: Renaming pwm.c/.h to softpwm.c/.h
    nrf5/drivers/pwm: Expose pwm_init() as public function.
    nrf5/modules/ubluepy: Making peripheral conn_handle volatile. Upon connection event, the variable is accessed in thread mode. However, the main-loop is blocking on conn_handle != 0xFFFF. If this is not volatile, optimized code will not exit the loop.
    nrf5/drivers/bluetooth: As callback functions are in most usecases are set to NULL upon last event to get public API function out of blocking mode, these function pointers has to be set as volatile, as they are updated to NULL in interrupt context, but read in blocking main-thread.
    nrf5/examples: Fixing overlapping function names and variable names inside the object. Also removing some print statements. Tuning max angle from -7/7 to -25/25.

    make BOARD=pca10028 flash
    ```
    and it will work properly.

nrf: Enable binascii, hashlib modules
2018-05-11 19:40:45 -07:00
Jeff Epler
471fdae993 nrf: Enable binascii, hashlib modules
These modules would be very handy to have in order to implement a
more robust replacement for ampy.  It costs around 2KiB of text and
no data or bss.

'binascii' has base64 encoding, which can be used to create a fully
8-bit-clean transport above the slightly cooked serial connection of
these boards.

'hashlib' is a bit less critical, but I have found it handy to
be able to robustly checksum remote files.

I see this as only being useful on ports which don't have USB block
device support, so atmel-samd doesn't need it.  These modules are
already on esp8266 so I think nrf52 seems like the only one that
needs it.

9962ea6449 nrf: Change pin names on DKs to match silkscreen
Quite a big revamp of the make-pins script, it is now used on each
build to generate the pin files, so the static ones are not needed
anymore.

021df5d3d3 nrf: Cleanup AnalogOut and throw an exception in constructor
The nRF MCUs do not support analog output. Throwing an exception
in the constructor will stop users from creating an instance of
the AnalogOut class.

In the future we can ifdef-out the whole class so it is not available
in the module at all.

1. Turn off MICROPY_CPYTHON_COMPAT, which includes a number of minor CPython compatibility features,
most of which have workarounds, but uses up significant flash.
2. Turn on MICROPY_PY_SYS_MAXSIZE, which implements sys.maxsize.
3. Turn on MICROPY_CAN_OVERRIDE_BUILTINS, which implements "_" as the most recent value in the REPL,
and also enables redefining builtins.
