Sming_RTOS Beta version

Sming based on Espressif RTOS SDK.

Based on: Sming Develop, including commits until Sming 2.1.0 release Based on: Espressif RTOS_SDK 1.3.0 Build

Feedback:

  • When finding issues during conversion of applications -> Submit an issue on the Sming_RTOS repository.

Requirements:

  • Espressif RTOS_SDK 1.3.0
  • UDK 2.0.9 for toolchain and SDK on Windows or esp-open-sdk on Linux
    • Be sure to have a "clean" sdk without previously applied updates
  • esp-alt-sdk provides downloads for all platforms, @kireevco to supply links

Usage:

  • Beware : Some Environment variables names are identical to SMING_NONOS !

  • Clone this repository.

  • SET environment variables valid for the location

  • Set SDK location in Makefile- or as environment variables -> SDK_BASE = ....

  • Set WIFI_SSID & WIFI_PWD in environment variables

  • Compile & flash

Additional needed software

Completeness:

  • All Core and Network functionality is ported to Sming_RTOS
  • Spiffy & Spiffs Filesystem functionality included

Applications:

  • Application which includes HttpAjax & HWPwm example source.
  • HttpAjax -> works
  • HWPWm, -> compiles, not tested on hardware
  • Neopixel -> working
  • ScannerI2C -> working
  • WebSockets -> working
  • SDCard -> working
  • HCSR04 Ultrasonic -> working
  • DHT11-22 -> DHT11 tested and working , DHT22 untested
  • SSD1306 Screen -> i2c module tested and working, spi module untested
  • DS1820 -> working
  • SystemClock&NTP -> working
  • BMP180 Pressure -> working
  • RBoot -> working
  • PCD8544 LCD (Nokia 5110 LCD) -> working

Known RTOS/NONOS differences with application consequences

Generic :

  • No WDT routines
  • Soft timer only on milli and not on micro level

SPI_SIZE

  • The espressif SDK is more restrictive on use of flash The SPI_SIZE needs to be set correct to prevent issues (especially Spiffs)

Include files :

  • The user_config.h file does not contain any framework includes anymore. -> Remove the NONOS user_config.h ! If not removed, there will be unresolved .h files
  • The directory structure has changed. The only include necessary is the #include "SmingCore.h" When using libraries use #include "libraries/......" For case sensitive systems : beware of naming

Spiffs

  • Spiffs FS'es created on NONOS are not supported -> Create a new spiffs using the RTOS supplied Spiffy !
  • When mounting the FS on Flash is checked for "Generic spiffy structure" (blocksize, FS length,..)
  • spiffs_mount() and spiffs_mount_manual return bool based on mount result
  • When using spiffs_mount() the size of the spiffs FS is autodetected.
  • When using spiffs_mount_manual()
    • use the actual flash address : For conversion of current spiffs_mount_manual : subtract 0x40200000 from start address
    • use filesize is 0 (zero) for autodetected size of FS
  • See the remark above on SPI_SIZE. If set not correct the spiffs_mount and spiffs_mount_manual will fail. rBoot
    • Works as in Sming but ... See the above on spiffs_mount_manual !
