* LiquidCrystal I2C 4-bit robustness
- Fix up some formatting
- Initialization is now more conformant with the datasheet.
- Read-backs don't needlessly (or erroneously!) store back
While here, document some unexpected behaviour of read-back commands.
* liquidcrystal i2c 4bit NTest
`ws2812` buffer extracted to new `pixbuf` module.
* The new pixbuf module has more functionality than the `ws2812`-specific buffer it replaces.
* This is work in progress towards https://github.com/nodemcu/nodemcu-firmware/issues/2916
* The LED driver modules `ws2812`, `ws2801`, `apa102`, and `tm1829` have sprouted `pixbuf` support.
* `NTest` tests for `pixbuf` now exist.
While here, document the ws2812 UART-based overlapping with mainline
execution. Fixes https://github.com/nodemcu/nodemcu-firmware/issues/3140

* Create mispec_file.lua
* Initial commit of gambiarra
* Adapt gambiarra to NodeMCU
* adapt to NodeMCU spacing and add nok functionality
* Some refactoring to make it easier to add new functionality
* Add methode `fail` to check failing code and pass error messages to output
- fail can be called with a function that should fail and a string which should be contained in the errormessage.
- Pass failed check reasons to output.
* Create gambiarra_file.lua
* Add reporting of tests that failed with Lua error
* ok, nok and fail will terminate the running test
* Add capability to run sync and async tests in mixed order and have a task.post inbetween them
* fix gambiarra self test to also run on device (not only host)
Use less ram in checking tests directly after they ran.
Use nateie task.post to tame watchdog.
* Update file tests + add async tmr tests
* Another fix in executing async test
* Catch errors in callbacks using node.setonerror
* change interface to return an object with several test methods
* Update README.md
* Change interface of Gambiarra + add reason for failed eq
* Update gambiarra documentation
* Add coroutine testcases to gambiarra
* Delete mispec_file.lua as it is superseeded by gambiarra_file.lua
* improve regexp for stack frame extraction
* Use Lua 53 debug capabilities
* move actual tests upfront
* remove debug code + optimization
* Show errors immediately instead of at the end of the test, freeing memory earlier
* Split tests to be run in 2 tranches
* rename to NTest and move to new location
* Add tests to checking mechanisms
* Add luacheck to tests
* Some pushing around of files
* more (last) fixes and file juggling
* Minor tweaks and forgotten checkin
* Add NTest selftest to travis
* Trying how to master travis
* another try
* restrict NTest selftest to linux
