-# FastLED-idf
+# FastLED-idf
+
+The ESP32 is a pretty great package. It has two
+cores, 240Mhz speed, low power mode, wifi and bluetooth, 
+and can be had in pre-built modules at prices between $24 ( Adafruit, Sparkfun ), $10 (Espressif-manufactured boards through Mauser and Digikey),
+or 'knock off' boards for $4 from AliExpress.
+
+If you're going to program this board, you might use Arduino.
+Although I love the concept of Arduino - and the amazing amount
+of libraries - the reality is the Arduino IDE is a mess, and the compile
+environment is "funky", that is, it's not really C - about my first
+minute in the IDE, I managed to write a perfectly valid C preprocessor
+directive that's illegal in Arduino.
+
+Enter ESP-IDF, which is Espressif's RTOS. It's based on FreeRTOS,
+but they had to fork it for multiple cores. It's based on FreeRTOS 9,
+but has some of the work done later backported.
+
+There are a TON of useful modules included with ESP-IDF. Notably,
+nghttp server, mdns, https servers, websockets, json, mqtt, etc etc.
+
+What I tend to do with embedded systems is blink LEDs! Sure, there's other
+fun stuff, but blinking LEDs is pretty good.
+
+Thus, we need FastLED.
+
+# The other FastLED-idf
+
+It appears that set of code was an earlier version of FastLED, 
+and probably only still works with ESP-IDF 3.x. There was a major
+update to ESP-IDF, a new build system, lots of submodule updates,
+cleaned up headers and names, which seem to be all for the better -
+but with lots of breaking changes.
+
+Thus, updating both, and using eskrab's version as a template, 
+I attempt to have a running version of FastLED with the ESP-IDF
+4.0 development environment
+
+# ESP-IDF already has a LED library
+
+Yes, I saw it once, I'm having trouble finding it now. It does
+really cool timing tricks, but it's not got all the fancy-fancy
+of the FastLED library, which has a better designed and time tested 
+programming interface. I reached out on the Espressif forum to the
+company and suggested they support FastLED ( why not? it's open source! )
+and they told me to get lost.
