Glenn Ruben Bakke 91fcde73d2 nrf/drivers/ticker: Rework ticker functions for microbit display/music. 
- Rename init function to ticker_init0.
- Implement ticker_register_low_pri_callback (recycle of unused
  set_low_priority_callback function which was unimplemented).
- Add support for registering 2 low pri callbacks.  For now, one intended
  for microbit display, and one for modmusic.

Glenn Ruben Bakke 7c74b7da48 nrf/drivers/softpwm: Rename init function to softpwm_init0. 2018-07-18 17:12:25 +10:00
Glenn Ruben Bakke d76982e382 nrf/boards/microbit: Include modmicrobit.h in board_modules.h. 
So that users of the board module can find the init function of the module
implicitly.

Glenn Ruben Bakke 0b504575e2 nrf/boards/microbit: Add modmicrobit.h to expose module init function. 2018-07-18 17:12:25 +10:00
Glenn Ruben Bakke 1b241be310 nrf/boards/microbit: Attempt to get working display/images without FP. 
And update the API to align with new unary/binary function callback
structures.
 2018-07-18 17:12:25 +10:00
Glenn Ruben Bakke 9e090a8783 nrf/boards/microbit: Add framework updates to build micro:bit modules. 
Makefile and mpconfigport.h update is generic, and could be used by other
boards to give extra modules which are only for a selected board.
 2018-07-18 17:12:25 +10:00
Glenn Ruben Bakke fbc45bd3f3 nrf/boards/microbit: Update board modules from C++ to C-code. 
This aligns implementation with new style structures.

Glenn Ruben Bakke f3386cfc50 nrf/boards/microbit: Rename display/image files from .cpp to .c ext. 
Also rename modmicrobit.h to microbitconstimage.h.

Glenn Ruben Bakke 7a2e136049 nrf/boards/microbit: Add copy of microbit display and image files. 
From micro:bit port repository, https://github.com/bbcmicrobit/micropython

Ayke van Laethem a248db6916 nrf: Option to enable Ctrl-C in NUS console. 
Costs 136 bytes on a nRF51822.

Ayke van Laethem 03b8429c0c nrf: Remove default FROZEN_MPY_DIR. 
Saves 448 bytes of flash. Can still be enabled using:

    make FROZEN_MPY_DIR=freeze BOARD=foo
 2018-07-18 17:12:25 +10:00
Glenn Ruben Bakke b493de75f3 nrf: Update usage of mp_obj_new_str by removing last parameter. 2018-07-18 17:12:25 +10:00
Ayke van Laethem fc5d89e29d nrf/drivers/bluetooth: Start advertising after disconnect. 
Disconnecting after a connect would not restart advertising, so
reconnecting may get harder.
 2018-07-18 17:12:25 +10:00
Ayke van Laethem 2561bcf0c0 nrf/main: Add ampy support. 
The ampy tool expects a "soft reboot" line when it does a soft reset.
 2018-07-18 17:12:25 +10:00
Glenn Ruben Bakke 2b32333f90 nrf: Use micropython libm to save flash 
Using libm from micropython free up about 5.5kb flash on nrf52
targets which have floating point enabled.
 2018-07-18 17:12:25 +10:00
Ayke van Laethem d9fb8c2585 nrf/main: Run boot.py and main.py on startup. 2018-07-18 17:12:25 +10:00
Ayke van Laethem 66e39d6a4e nrf/modules/uos/microbitfs: Make OSError numeric. 
This saves about 80 bytes of code size.
 2018-07-18 17:12:25 +10:00
Ayke van Laethem 8482daced2 nrf/drivers/bluetooth/ble_drv: Don't handle non-events. 
When there is a non-BLE event (sd_evt_get), the ble_evt_handler is
invoked anyway even if it returns NRF_ERROR_NOT_FOUND.
 2018-07-18 17:12:25 +10:00
Ayke 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.
 2018-07-18 17:12:25 +10:00
Ayke van Laethem 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).

Ayke van Laethem 83f38a99a9 nrf/hal/hal_nvmc: Fix non-SD code. 
The code wasn't tested yet without a SoftDevice.
 2018-07-18 17:12:25 +10:00
Glenn Ruben Bakke a2b4c93e85 nrf/hal/nvmc: Remove pre-compiler error thrown in nvmc.h, if on nrf52. 
This has been tested and works.
 2018-07-18 17:12:25 +10:00
Ayke van Laethem 7418795fdf nrf: Disable FAT/VFS by default. 
Most boards don't have an SD card so it makes no sense to have it
enabled. It can be enabled per board (mpconfigboard.h).
 2018-07-18 17:12:25 +10:00
Ayke van Laethem cc158f98fe nrf: Implement NVMC HAL. 
This is only a library for flash access. Actual file system support will
be added later.
