Changes have been kept to a minimum, but a serious chunk of work was
needed to move from 8266isms to IDFisms.
Some things got refactored into components/lua/common, in particular
the LFS location awareness.
As part of this work I also evicted our partition table manipulation
code, as with the current IDF it kept breaking checksums and rendering
things unbootable, which is the opposite of helpful (which was the
original intent behind it).
The uart module got relocated from base_nodemcu to the modules component
properly, after I worked out how to force its inclusion using Kconfig alone.
The uzlib and parts of Lua had to be switched over to use the
C standard int types, as their custom typedefs conflicted with
RISC-V toolchain provided typedefs.
UART console driver updated to do less direct register meddling
and use the IDF uart driver interface for setup. Still using our
own ISR rather than the default driver ISR. Down the line we
might want to investigate whether the IDF ISR would be a better
fit.
Lua C modules have been split into common and ESP32/ESP32-S
specific ones. In the future there might also be ESP32-C3
specific modules, which would go into components/modules-esp32c3
at that point.
Our old automatic fixup of flash size has been discarded as it
interferes with the checksumming done by the ROM loader and
results in unbootable systems. The IDF has already taken on
this work via the ESPTOOL_FLASHSIZE_DETECT option, which handles
this situation properly.
Using the NODEMCU_ namespace prefix makes it obvious that these are not
part of Lua proper (contrast, e.g., LUA_BUILTIN_STRING). Using
"CMODULE" gives us room to differentiate between modules whose
implementation is in C and whose implemenation is in Lua ("LMODULE").
The ESP8266 branch can adopt the same convention when it moves to
Kconfig; see https://github.com/nodemcu/nodemcu-firmware/issues/3130
* Leaner, meaner crypto module; now with HMAC
Based on my testing, mbedtls pulls in all its algorithm regardless of
whether the NodeMCU crypto module was using them or not. As such, the
space savings from omitting algorithms were only in the tens of bytes.
By switching to using the mbedtls generic message digest interface, the
crypto module itself could be shrunk in size and complexity. Despite
adding support for HMAC on all algorithms (plus including RIPEMD160),
this version is 330 bytes smaller.
* Updated crypto module docs.
* Removed superfluous brackets in crypto docs.
Copy-paste considered harmful... >.>
* ESP32: Added pulsecnt module
The pulsecnt module let's you use the ESP32's pulse counter capabilities from Lua.
* ESP32: Pulsecnt module. Better/faster callback.
Reduced the amount of callback variables to speed things up and shift more logic to Lua than in the C code.
* ESP32: Completed docs for pulsecnt
* ESP32: Final release of pulsecnt
* ESP32: Production release of pulsecnt
* ESP32: Release (tweaked docs)
* ESP32: Pulse Counter Release. Cleaned up .gitignore
* ESP32: Pulse counter release (changed ch1 gpio to int to match ch0)
* ESP32: Add time modules
New time module for manipulating system time/ calendar and controlling SNTP server
* ESP32: Time module documentation & style fixes
* added documentation for time modules
* style fixes as pointed out by @devsaurus
* ESP32: Time module small fixes
* Couple small fixes
* Esp32: Add SJSON module
This adds SJSON module taken directly from master
* ESP32: Fixes for sjson lib
Fixed compilation not including config header, thus braking some of libs functionality
* ESP32: Upgraded SJSON to master
* Adding qrcodegen module for generating QR Codes
* Added LUA_MODULE_QRCODEGEN KConfig
* Changed qrcodegen.encodeText() to use an options table
Created common.h with new option table helper fns.
* Reworked http.c to use new common.h options table APIs
* Inital commit for supporting ledc driver
* Added documentation. More fade functions and better naming of constants
* Better field checking during setup. Updated documentation
* Reworked LEDC module to be used with an object model to decrease repetition of parameters
* can extension
* can extension: bit timing and filter
* can -> CAN
* post CAN data callback
* CAN docs
* CAN: fixed receive, filter, extended frame
* reorder fn in can.md, remove driver_can/Kconfig
* fixed a leak when can.stop()
Based on his revision 2d290a24a0914be88e5ca4ac7b1018392fe75fe2
(https://github.com/djphoenix/nodemcu-firmware).
All LWIP callback handling changed to use the NodeMCU task interface
to make it usable on RTOS.
IPv4 assumptions have been removed, and this net module /should/ now
be IPv6 ready, but aside from compilation no testing has been done
in this area.
SSL integration points not touched - some work needed there once we
have an mbedTLS module.
RTOS driver evicted as it did not play nice with stdio etc.
Implemented a minimal driver to fully support Lua console on UART0. Output
on UART0 done via stdout (provided by the IDF). Input and setup handled
via driver_console/console.c. In addition to the direct input function
console_getc(), the driver also registers in the syscall tables to enable
regular stdio input functions to work (yay!). The Lua VM is still using the
direct interface since it's less overhead, but does also work when going
through stdin/fd 0.
Auto-bauding on the console is not yet functional; revisit when the UART docs
are available.
Module registration/linking/enabling moved over to be Kconfig based. See
updates to base_nodemcu/include/module.h and base_nodemcu/Kconfig for
details.
The sdk-overrides directory/approach is no longer used. The IDF is simply
too different to the old RTOS SDK - we need to adapt our code directly instead.
Everything in app/ is now unused, and will need to be gradually migrated
into components/ though it is probably better to migrate straight from the
latest dev branch.
