Plenty of dependency adjustments, printf format specificier updates,
FreeRTOS type and macro name modernisation, not to mention API changes.
Still plenty of legacy/deprecated drivers in use which will need updating.
The following features have been removed due to no longer being available
from the IDF:
- ADC hall effect sensor reading
- Configuration of SD SPI host via sdmmc module (now must be done first
via the spimaster module)
- FAT partition selection on external SD cards; only the first FAT
partition is supported by the IDF now
On the other hand, the eth module now supports the following new chipsets:
- KSZ8001
- KSZ8021
- KSZ8031
- KSZ8051
- KSZ8061
- KSZ8091
- Possibly additional models in the LAN87xx series (the IDF docs aren't
clear on precisely which models are handled)
Further, the sdmmc module is now available on the ESP32-S3 as well.
In addition to exposing additional configuration settings, it now also
provides access to the wifi station power-saving control.
Documentation updated, and wifi.sta.getconfig() has been documented. Not
sure why that wasn't already the case.
By returning result as a signed 32-bit int between INT32_MIN to IN32_MAX
which is represented the same regardless of 64-bit support or
integral-only builds.
Also updated docs, fixed links and clarified behavior of random APIs
when WiFi isn't started.
* Adding the first version of the rmt documentation.
* Stub RMT module compiles.
* This version seems to work in (at least) simple cases.
* CLean up the docs
* Minor fixes
* Give the SPI module a chance of working...
* Update to the released version of idf4.4
* Try to get the CI Build to work in all cases
* Try to get the CI Build to work in all cases
* FIx a ringbuffer return issue
* Remove bogus comment
* Review comments
* Better example of transmission
* Review comments
* Add table send example
* Improved documentation
* Documentation comments
* Install the driver correctly.
* A couple of doc updates
* Fix typo
Also removed old, very unsafe node.osoutput(). We're now integrating cleanly
with the IDF/newlib way of redirecting stdout.
Added necessary depends in Kconfig to ensure VFS support is enabled, as
otherwise you'd only get a mysterious crash when attempting to enable
output redirection.
The IDF-provided VFS resolves several issues:
- The IDF components having a different view of the (virtual) file system
compared to the Lua environment.
- RTOS task/thread safety. Our legacy VFS was only ever safe to use
from the LVM thread, which limited its usability. Upgrading it
would have effectively required a reimplementation of the IDF VFS,
which would have been a bigger task with larger on-going maintenance
issues.
- We're no longer needing to maintain our own SPIFFS component.
- We're no longer needing to maintain our own FATFS component.
- The legacy of the 8266's lack of standard C interface to the file system
is no longer holding us back, meaning that we can use the standard
Lua `io` module rather than the cobbled-together swiss army knife
also known as the file module.
Of course, the downside is that we'll either have to declare a backwards
breakage in regard to the file module, or provide a Lua shim for the old
functions, where applicable.
Also included is some necessary integer type fixups in unrelated code,
which apparently had depended on some non-standard types in either the
SPIFFS or FATFS headers.
A memory leak issue in the sdmmc module was also found and fixed while
said module got switched over to the Espressif VFS.
Module documentation has been updated to match the new reality (and I
discovered in some places it wasn't even matching the old reality).
