Low Memory Watermark is compared to DEFAULT_LOW_MEM_THRESHOLD (currently set at 80,000 bytes) after HAP initialization but before WIFI connection. If Low Memory Watermark is below DEFAULT_LOW_MEM_THRESHOLD, a WARNING is issued.
Note: memory is based on heap with MALLOC_CAP_DEFAULT capabilities
Adds a second type of WiFi Callback that is called every time WiFi is established OR re-established after a disconnect. Passes the number of times WiFi has been connected as an argument.
Allows extension of initial table produced in WebLog, where f is a function that returns a String. The returned String is copied into the WebLog HTML just before the </table> tag is printed in the initial table.
Changed fixed-size array `struct Controller[MAX_CONTROLLERS]` to a dynamic linked-list of Controllers. Re-coded all related functions. MAX_CONTROLLERS no sets the size of any buffers but is only used to limit the ultimate size of the linked-list.
Saved about 1K of RAM since most of the time there are only 2 Controllers defined (as opposed to the 16 allowed).
* Added support for zero-length TLV
* Added SEPARATOR as a formal kTLVType (and updated listControllers() to use)
* Added `uint8_t *buf(tagType tag, uint8_t *src, int len);` to load buffer needing external memcpy (and updated listControllers() to use)
Optimized use of heap memory instead of stack memory for temporary variables, and makes code easier to read, provided all heap usage is free() at end of each function.
Also removed char *hostName as a member variable of homeSpan. It's never actually used since MDNS constructs its own copy of hostName as needed.
changed nPixels from uint8_t to int to allow for longer pixel strands (library is coded for int, so there is no need to limit to uint8_t in the example).
