2020-07-22nrf: Split mpconfigport.h into multiple files.Glenn Ruben Bakke
Splitting mpconfigport.h into multiple device specific files in order to facilitate variations between devices. Due to the fact that the devices might have variations in features and also variations in flash size it makes sense that some devices offers more functionality than others without being limited by restricted devices. For example more micropython features can be activated for nrf52840 with 1MB flash, compared to nrf51 with 256KB.
2020-07-22lib/libc: Fix string0's implementation of strncpy.Damien George
Fixing 98e583430fb7b793119db27bad9f98119e81579f, the semantics of strncpy require that the remainder of dst be filled with null bytes. Signed-off-by: Damien George <damien@micropython.org>
2020-07-21lib/libm_dbl: Add round.c source code.Zoltán Vörös
This code is imported from musl, to match existing code in libm_dbl. The file is also added to the build in stm32/Makefile. It's not needed by the core code but, similar to c5cc64175be32cb1e4f3f1a249667bc9f5a12613, allows round() to be used by user C modules or board extensions.
2020-07-21py/obj.h: Fix mp_seq_replace_slice_no_grow to use memmove not memcpy.Damien George
Because the argument arrays may overlap, as show by the new tests in this commit. Also remove the debugging comments for these macros, add a new comment about overlapping regions, and separate the macros by blank lines to make them easier to read. Fixes issue #6244.

2020-07-21docs/library: Update documentation of esp32's RMT.Jonathan Hogg
This explains how looping now works, and removes the warning about calling wait_done().
2020-07-21esp32/esp32_rmt: Properly fix looping behaviour of RMT.Jonathan Hogg
A previous commit 3a9d948032e27f690e1fb09084c36bd47b1a75a0 can cause lock-ups of the RMT driver, so this commit reverses that, adds a loop_en flag, and explicitly controls the TX interrupt in write_pulses(). This provides correct looping, non-blocking writes and sensible behaviour for wait_done(). See also #6167.
2020-07-21extmod/modussl_mbedtls: Integrate shorter error strings.Thorsten von Eicken
The stm32 and esp32 ports now use shorter error strings for mbedtls errors. Also, MBEDTLS_ERROR_C is enabled on stm32 by default to get these strings.
2020-07-20lib/mbedtls_errors: Add code to patch mbedtls for shortened error strs.Thorsten von Eicken
The file `mbedtls_errors/mp_mbedtls_errors.c` can be used instead of `mbedtls/library/error.c` to give shorter error strings, reducing the build size of the error strings from about 12-16kB down to about 2-5kB.
2020-07-20lib/libc: Add implementation of strncpy.Thorsten von Eicken
2020-07-20extmod/modussl: Improve exception error messages.Thorsten von Eicken
This commit adds human readable error messages when mbedtls or axtls raise an exception. Currently often just an EIO error is raised so the user is lost and can't tell whether it's a cert error, buffer overrun, connecting to a non-ssl port, etc. The axtls and mbedtls error raising in the ussl module is modified to raise: OSError(-err_num, "error string") For axtls a small error table of strings is added and used for the second argument of the OSErrer. For mbedtls the code uses mbedtls' built-in strerror function, and if there is an out of memory condition it just produces OSError(-err_num). Producing the error string for mbedtls is conditional on them being included in the mbedtls build, via MBEDTLS_ERROR_C.
2020-07-20docs/library: For ubluetooth, add docs for _IRQ_GATTS_INDICATE_DONE.Jim Mussared
2020-07-20extmod/modbluetooth: Add event for "indicate acknowledgement".Jim Mussared
This commit adds the IRQ_GATTS_INDICATE_DONE BLE event which will be raised with the status of gatts_indicate (unlike notify, indications require acknowledgement). An example of its use is added to ble_temperature.py, and to the multitests in ble_characteristic.py. Implemented for btstack and nimble bindings, tested in both directions between unix/btstack and pybd/nimble.
2020-07-20extmod/modbluetooth: Fix so it builds in peripheral-only mode.Jim Mussared
2020-07-20extmod/modbluetooth: Ignore unused self_in in ble_gatts_indicate.Jim Mussared
2020-07-18docs/library: Add gatts_indicate() doc to ubluetooth.rst.Jim Mussared
Also clarify behavior of `gatts_notify` and add some TODOs about adding an event for indication acknowledgement.
2020-07-18examples/bluetooth: Add simple UART demo with central and peripheral.Jim Mussared
2020-07-18extmod/btstack: Schedule notify/indicate/write ops for bg completion.Jim Mussared
The goal of this commit is to allow using ble.gatts_notify() at any time, even if the stack is not ready to send the notification right now. It also addresses the same issue for ble.gatts_indicate() and ble.gattc_write() (without response). In addition this commit fixes the case where the buffer passed to write-with-response wasn't copied, meaning it could be modified by the caller, affecting the in-progress write. The changes are: - gatts_notify/indicate will now run in the background if the ACL buffer is currently full, meaning that notify/indicate can be called at any time. - gattc_write(mode=0) (no response) will now allow for one outstanding write. - gattc_write(mode=1) (with response) will now copy the buffer so that it can't be modified by the caller while the write is in progress. All four paths also now track the buffer while the operation is in progress, which prevents the GC free'ing the buffer while it's still needed.

2020-07-18unix: Make the MICROPY_xxx_ATOMIC_SECTION mutex recursive.Jim Mussared
This mutex is used to make the unix port behave more like bare metal, i.e. it allows "IRQ handlers" to run exclusively by making the mutex recursive.
2020-07-17travis: Change nrf pca10056 board to build with s140 SoftDevice.Glenn Ruben Bakke
It might compile fine with S132 as SoftDevice for nRF52840. However, there might be different hardware on the SoC which in turn could make it fail. SoftDevice S140 is correct BLE stack for nRF52840 SoC and would provide a more accurate test build.

2020-07-08nrf: Enable nrf tick support on all boards by default.Martin Fischer
Having time.ticks_ms/us/add/diff is very useful and used by many drivers, libraries and components.
2020-07-08nrf: Add support for time.ticks_xxx functions using RTC1.Martin Fischer
This commit adds time.ticks_ms/us support using RTC1 as the timebase. It also adds the time.ticks_add/diff helper functions. This feature can be enabled using MICROPY_PY_TIME_TICKS. If disabled the system uses the legacy sleep methods and does not have any ticks functions. In addition support for MICROPY_EVENT_POLL_HOOK was added to the time.sleep_ms(x) function, making this function more power efficient and allows support for select.poll/asyncio. To support this, the RTC's CCR0 was used to schedule a ~1msec event to wakeup the CPU. Some important notes about the RTC timebase: - Since the granularity of RTC1's ticks are approx 30usec, time.ticks_us is not perfect, does not have 1us resolution, but is otherwise quite usable. For tighter measurments the ticker's 1MHz counter should be used. - time.ticks_ms(x) should *not* be called in an IRQ with higher prio than the RTC overflow irq (3). If so it introduces a race condition and possibly leads to wrong tick calculations. See #6171 and #6202.
2020-07-01nrf/Makefile: Disable ROM text compression when compiling for debug.Glenn Ruben Bakke
When compiling for debug (-O0) the .text segment cannot fit the flash region when MICROPY_ROM_TEXT_COMPRESSION=1, because the compiler does not optimise away the large if-else chain used to select the correct compressed string. This commit enforces MICROPY_ROM_TEXT_COMPRESSION=0 when compiling for debug (DEBUG=1).
2020-07-01nrf/bluetooth/ble_uart: Swap end character on cooked strings.Glenn Ruben Bakke
Changing line ending character of cooked strings makes rshell/pyboard.py work correctly over Bluetooth socat/pts devices.
2020-07-01nrf/bluetooth/ble_uart: Fix random advertisement name.Glenn Ruben Bakke
The storage space of the advertisement name is not declared static, leading to a random advertisement name. This commit fixes the issue by declaring it static.
2020-07-01nrf/bluetooth/ble_uart: Add mp_hal_stdio_poll function.Glenn Ruben Bakke
This adds support for enabling MICROPY_PY_SYS_STDFILES when running UART over Bluetooth (NUS).
2020-07-01nrf/bluetooth: Handle data length update request.Glenn Ruben Bakke
The Bluetooth link gets disconnected when connecting from a PC after 30-40 seconds. This commit adds handling of the data length update request. The data length parameter pointer is set to NULL in the reply, letting the SoftDevice automatically set values and use them in the data length update procedure.
2020-07-01nrf/bluetooth/ble_uart: Fix implicit declaration of function.Glenn Ruben Bakke
mp_keyboard_interrupt() triggers a compiler error because the function is implicitly declared. This commit adds "py/runtime.h" to the includes. Fixes issue #5732.
2020-07-01unix: Enable uasyncio on dev variant.Jim Mussared
2020-07-01unix: Make manifest selection match other ports.Jim Mussared
Changes are: - The default manifest.py is moved to the variants directory (it's in "boards" in other ports). - The coverage variant now uses a custom manifest in its variant directory to add frzmpy/frzstr. - The frzmpy/frzstr tests are moved to variants/coverage/.
2020-07-01Revert "tools/pydfu.py: Respect longer timeouts requested by DFU dev..."Andrew Leech
This reverts commit 4d6f60d4286b3e6ea8c9fb0141ba13e4978882b6. This implementation used the timeout as a maximum amount of time needed for the operation, when actually the spec and other tools suggest that it's the minumum delay needed between subsequent USB transfers.
2020-07-01stm32/mboot: Disable polling mode by default and use IRQ mode instead.Andrew Leech
Polling mode will cause failures with the mass-erase command due to USB timeouts, because the USB IRQs are not being serviced. Swiching from polling to IRQ mode fixes this because the USB IRQs can be serviced between page erases. Note that when the flash is being programmed or erased the MCU is halted and cannot respond to USB IRQs, because mboot runs from flash, as opposed to the built-in bootloader which is in system ROM. But the maximum delay in responding to an IRQ is the time taken to erase a single page, about 100ms for large pages, and that is short enough that the USB does not timeout on the host side. Recent tests have shown that in the current mboot code IRQ mode is pretty much the same speed as polling mode (within timing error), code size is slightly reduced in IRQ mode, and IRQ mode idles at about half of the power consumption as polling mode.
2020-07-01stm32/mboot: Remove the use of timeout in DFU_GETSTATUS.Andrew Leech
This is treated more like a "delay before continuing" in the spec and official tools and does not appear to be really needed. In particular, downloading firmware is much slower with non-zero timeouts because the host must pause by the timeout between sending each DFU_GETSTATUS to poll for download/erase complete.
2020-06-30py: Rework mp_convert_member_lookup to properly handle built-ins.Damien George
This commit fixes lookups of class members to make it so that built-in functions that are used as methods/functions of a class work correctly. The mp_convert_member_lookup() function is pretty much completely changed by this commit, but for the most part it's just reorganised and the indenting changed. The functional changes are: - staticmethod and classmethod checks moved to later in the if-logic, because they are less common and so should be checked after the more common cases. - The explicit mp_obj_is_type(member, &mp_type_type) check is removed because it's now subsumed by other, more general tests in this function. - MP_TYPE_FLAG_BINDS_SELF and MP_TYPE_FLAG_BUILTIN_FUN type flags added to make the checks in this function much simpler (now they just test this bit in type->flags). - An extra check is made for mp_obj_is_instance_type(type) to fix lookup of built-in functions. Fixes #1326 and #6198. Signed-off-by: Damien George <damien@micropython.org>
2020-06-30py/obj.h: Make existing MP_TYPE_FLAG_xxx macros sequential.Damien George
