      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.

      Fix platform_rmt_allocate for esp32-S3 · 7155d719
      Tom Sutcliffe authored
      By not relying on ifdefing for specific targets, but instead using the
      SOC_RMT_xxx macros to figure it out.

      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.

      Make sodium.random API behave consistently on all build types · a40d69db
      Tom Sutcliffe authored
      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.

      Fix file.list() zero sizes. Fixes #3549. · e3883cd2
      Tom Sutcliffe authored
      The modern spiffs backend doesn't like stat("./somefile") for something
      on the root of the filesystem, and instead only accepts "somefile"
      (it also doesn't like "/somefile"). The error from stat was being
      ignored which is why the file sizes all appeared to be zero.
      
      The fix is to change file.list() to pass just the filename, unless a
      directory was passed to list(). Also improved error handling a bit.
