Key assumption: All of the offsets in mp_execute_bytecode fit in 16 bits; it is not clear whether the compiler will verify this assumption (e.g., by warning that a constant will be truncated) 2020-12-16T02:12:59+00:00 Scott Shawcroft scott@tannewt.org 2020-12-09T01:13:00+00:00 urn:sha1:1ad49d9a18224ecc53d8f49d0675a369274556ce Fixes #3787 2020-07-06T18:16:25+00:00 Diego Elio Pettenò flameeyes@flameeyes.com 2020-06-03T22:40:05+00:00 urn:sha1:34b4993d63a6b576f29d624385c681f679b4124c 2020-01-18T01:36:08+00:00 Scott Shawcroft scott@tannewt.org 2020-01-09T04:32:45+00:00 urn:sha1:7d8dac9211dab92d750a0351335b4ad3fffc05e2 Introduces a way to place CircuitPython code and data into tightly coupled memory (TCM) which is accessible by the CPU in a single cycle. It also frees up room in the corresponding cache for intermittent data. Loading from external flash is slow! The data cache is also now enabled. Adds support for the iMX RT 1021 chip. Adds three new boards: * iMX RT 1020 EVK * iMX RT 1060 EVK * Teensy 4.0 Related to #2492, #2472 and #2477. Fixes #2475. 2019-10-22T01:57:03+00:00 Scott Shawcroft scott@tannewt.org 2019-09-14T19:40:24+00:00 urn:sha1:ae30a1e5aa198bdeee7dce04194b027ff4e3d65a This PR refines the _bleio API. It was originally motivated by the addition of a new CircuitPython service that enables reading and modifying files on the device. Moving the BLE lifecycle outside of the VM motivated a number of changes to remove heap allocations in some APIs. It also motivated unifying connection initiation to the Adapter class rather than the Central and Peripheral classes which have been removed. Adapter now handles the GAP portion of BLE including advertising, which has moved but is largely unchanged, and scanning, which has been enhanced to return an iterator of filtered results. Once a connection is created (either by us (aka Central) or a remote device (aka Peripheral)) it is represented by a new Connection class. This class knows the current connection state and can discover and instantiate remote Services along with their Characteristics and Descriptors.

Ctrl-C stopped producing KeyboardInterrupt with this change on CircuitPython. The Unix and stm32 ports handles Ctrl-C differently with a handler which is probably why they where not affected.

The optimization drops the untranslated strings and replaces them with a compressed_string_t struct. It can then be decompressed to a c string. Builds without LTO work as well but include both untranslated strings and compressed strings. This work could be expanded to include QSTRs and loaded strings if a compress method is added to C. Its tracked in #531.
