      Fix uart.on('data') on console · 53da95b5
      Jade Mattsson authored
      With the switch to use the IDF's stdin for feeding the Lua VM, we
      unintentionally lost the ability to use uart.on('data') on the console uart.
      This is since we no longer install the nodemcu uart driver on said uart.
      In order to resolve this shortcoming, this commit refactors the uart.on('data')
      delimiter handling and moves it away from platform.c into uart.c where it
      really belongs. A new function, uart_feed_data(), is introduced, which is used
      both by the nodemcu uart driver task as well as the nodemcu console driver
      task (assuming the console is in fact a uart).
      
      The linebuffer allocation/freeing is still in response to
      uart.start()/uart.stop(), but it is now in uart.c rather than
      platform.c.
      
      The whole uart integration is still too tightly coupled between the platform
      component and the module component's uart.c, but this makes it slightly
      better at least.

      Initial support for ESP32-C6 and ESP32-H2, plus assorted fixes & improvements (#3646) · 4cdebe71
      Jade Mattsson authored
      
      
      * Proof-of-concept multi-type console support via stdio
      
      * Address crashes on linput's use of printf.
      
      On an empty line input, a C3 with UART console would panic while attempting
      to output the new Lua prompt. The backtrace shows a xQueueSemaphoreTake
      with uxItemSize==0 as the panic cause, deep inside the uart driver, invoked
      via vfs_uart and vfs_console layers, from printf.
      Similarly, the printf for outputting a backspace/erase sequence would also
      trigger a panic.
      
      This workaround (of not mixing fflush() with printf) is likely merely hiding
      a deeper issue, but it appears to be consistent. Plus, printf with no args
      and a user-supplied format string is a no-no and should be fixed anyway.
      
      * Work around IDF inconsistency with stdout buffering.
      
      * Increase console task stack size.
      
      Seems on Xtensa it ended up not being enough.
      
      * Switch to single-byte console reads.
      
      * Stop cheating and feed Lua from the right context.
      
      * Work around IDF buffering stdout even when told not to, on ACM consoles.
      
      * Initial build support for esp32c6.
      
      Plus fixup of module selection for a variety of targets.
      
      * Update github actions to node 20 versions.
      
      * Update github build to deal with Lua 5.3 being default.
      
      * Address fatal compiler warning.
      
      Newer IDF toolchain is stricter, and we'd apparently failed to build test
      the Lua-5.1 path for some time.
      
      * Initial build support for esp32h2.
      
      * Upgrade IDF to v5.1.3
      
      * Fix left-over incorrect type in uzlib.
      
      * Avoid null pointer crashes when debugging startup.
      
      * Workaround for using wifi module on S2 with USB-CDC console.

      Update rmt translator (#3629) · 14cdff10
      Christoph Thelen authored
      * Choose the number of RMT buffers in the ws2812 module.
      
      The number of buffers required for optimal operation should be selected
      by the ws2812 module, not the caller.
      
      * Add parameters for RGB LED bit times.
      
      This patch adds compatibility for different RGB LEDS besides the WS2812.
      ESP evaluation boards like the ESP32-C3-DevKitM-1 use an SK68XXMINI-HS
      RGB LED which does not respond to the timings of this module.
      The patch adds optional parameters for the bit timings to the write
      function. If the new parameters are not supplied, the old values are used.
      An example for the SK68XXMINI-HS is provided in the documentation.
      
      * Remove restrictions from RTM translator.
      
      The old RMT translator was not able to split the bits of the source
      data into the size requested by the RMT transmitter. Either all 8 bits
      of an input byte were translated or none.
      The new routine removes the restriction by delivering exactly the
      requested amount of data to the transmitter, which results in a more
      balanced buffering of translated data under load.
      
      * Add a parameter for the RGB LED reset time.
      
      This patch introduces a new optional parameter for the reset time
      in the RGB LED communication. The default is 51.2 microseconds. A
      value of 0 sends no reset signal, which allows a small optimisation
      for consecutive write commands.
      
      Please note that the reset time of the old code should be 50
      microseconds, as the define WS2812_DURATION_RESET suggested. Due to the
      restrictions of the old RMT translator routine, it was slightly
      increased to 51.2 microseconds. This patch keeps the value of 51.2
      microseconds to be as compatible as possible.
      
      * Minimize the time drift between RMT channels.
      
      Place all RMT channels in a group to minimize the time drift between
      the signals. Please note that this feature is not available on all
      platforms.
      
      * Fix the description of the SK6812 LED in the example code.
      
      The SK6812 expects the data for the green LED first, then red and
      finally blue. It should be described as a GRB LED.

      Initial migration to IDFv5.0 · f126b6fe
      Johny Mattsson authored
      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.

      Fix ws2812 on later esp32 variants · 1b38d8e6
      Tom Sutcliffe authored
      By not relying on the internal details of the RMT registers. For example
      on the esp32s2, the threshold event bits start at bit 12 not bit 24, and
      on the esp32s3 the memory buffers are only 48 words not 64. Also the
      esp-idf recommends against hooking the rmt ISR in the first place.
      
      Instead, use the published rmt APIs (specifically rmt_write_sample and
      rmt_translator_init) and the default rmt ISR, which should be much more
      resilient against future esp32 SoC changes.

      Switch to IDF-provided VFS and standard `io` module. · a2ba49e3
      Johny Mattsson authored
      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).

      Discard old console driver. · fbef7fea
      Johny Mattsson authored
      The IDF provides all we need these days, and the old driver was just
      needlessly conflicting with the IDF settings and setup.
      
      This also simplifies our uart input path as we no longer need to
      duplicate the raw byte handling for when "run_input" is false.

      Port Terry's Lua 5.1 + 5.3 work from the esp8266 branch. · 17df207a
      Johny Mattsson authored
      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.

      Add ESP32C3 support/coexistence. · f123d462
      Johny Mattsson authored
      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.

      Fix uart regressions & bugs (#2817) · b0558d5b
      Johny Mattsson authored
      * Fix uart regressions & bugs.
      
      Using `uart.on()` with a search character was broken in that it did
      not invoke the callback on a full UART buffer as documented. Logic reworked
      to match docs again.
      
      Fixed memory leak on `task_post()` failure (eep!).
      
      Improved logic to attempt to coalesce input bytes to reduce the number of
      `task_post()` slots used up by the platform uart.
      
      Finally, added a semaphore to prevent the platform uart from overrunning
      the `task_post()` slots all the time on high baud rates (e.g. 1mbit).
      With the semaphore in there, the LVM RTOS task gets a chance to actually
      process the received data and free up a `task_post()` slot or two.
      The above mentioned read coalescing then allows the platform uart to
      immediately catch up.
      
      Also added an error log message if the `task_post()` actually does fail.
      
      * Don't cache the uart delims.
      
      Doing so makes reconfiguring those settings from within the callback not
      take effect until the currently buffered bytes have been processed.
