-The canonical source for information is the [FreeRTOS Web Site](https://www.freertos.org/ "FreeRTOS").
-Within this site, the [Getting Started](https://www.freertos.org/FreeRTOS-quick-start-guide.html "Quick Start Guide") page is very useful.

 I have a short blog post on [Arduino FreeRTOS](https://feilipu.me/2015/11/24/arduino_freertos/), and another much older post on using [FreeRTOS with AVR](https://feilipu.me/2011/09/22/freertos-and-libraries-for-avr-atmega/), which may be useful to read too. There are some further posts I've written on [Hackster.IO](https://www.hackster.io/feilipu), but they're essentially the same content.

 Time slices can be selected from 15ms up to 500ms. Slower time slicing can allow the Arduino MCU to sleep for longer, without the complexity of a Tickless idle.
 
 Watchdog period options:
-* WDTO_15MS
-* WDTO_30MS
-* WDTO_60MS
-* WDTO_120MS
-* WDTO_250MS
-* WDTO_500MS

-Note that Timer resolution is affected by integer math division and the time slice selected. Trying to measure 100ms, using a 60ms time slice for example, won't work.

-Stack for the loop() function has been set at 192 bytes. This can be configured by adjusting the configMINIMAL_STACK_SIZE parameter. If you have stack overflow issues, just increase it.
-Users should prefer to allocate larger structures, arrays, or buffers using pvPortMalloc(), rather than defining them locally on the stack.

 This option has been selected because it is automatically adjusted to use the capabilities of each device.
 Other heap allocation schemes are supported by FreeRTOS, and they can used with additional configuration.

+* Stack Overflow: If any stack (for the `loop()` or) for any Task overflows, there will be a slow LED blink, with 4 second cycle.
 * Heap Overflow: If any Task tries to allocate memory and that allocation fails, there will be a fast LED blink, with 100 millisecond cycle.
 
 ## Errata
 
-Testing with the Software Serial library shows some incompatibilities at low baud rates (9600), due to the extended time this library disables the global interrupt.

 ## Files & Configuration
 
-* Arduino_FreeRTOS.h : Must always be #include first. It references other configuration files, and sets defaults where necessary.
-* FreeRTOSConfig.h : Contains a multitude of API and environment configurations.
-* FreeRTOSVariant.h : Contains the AVR specific configurations for this port of freeRTOS.
-* heap_3.c : Contains the heap allocation scheme based on malloc(). Other schemes are available, but depend on user configuration for specific MCU choice.
