Best 2018 for everybody.

In 2017, the best thing is the concrete progress in 4xx pill development. Small surprises for me in 2017 were:
- CubeMx HAL and LL are not gaining popularity in this forum
- ESP32 board prices have come down, but not eroding interest in F103/F407

Cheers, Ollie

Actually, in my mind and workshop, they are. Between the ESP32 at under $8 from AliExpress and the often available rPi_Zero_W for $5 from Microcenter here in Atlanta, the 20K SRAM in the STM32F1xx is surprisingly meager. I'm viewing the Maple Mini like I used to view the Arduino mini or micro... that is, a cheap utility board that just happens to be programmable.

The great thing about the ESP32 (and ESP8266) is that one can use SPIFFS to gain some serious table capability. Now I used to think of all that dead flash as just a wasted resource to be used in the n+1 program revision, but with a little creative thinking, the uC can be a real powerhouse for table-based calculations, etc.

I have an example here: https://www.hackster.io/rayburne/oui-ou ... 266-323ae4
In this prototype, I have included the ability to store the entire Organizationally Unique Identifier database in SPIFFS ... about 800K

I' m old and in college calculators were just beginning to be allowed. Most engineering was still slide-rule and look up tables. One can do a lots with a table. :lol:
At 80MHz, the ESP8266 requires 43 seconds worst-case to read the OUI data in flash and parse through the dataset looking for a specific OUI. The goal of this project is to reduce accessing any single OUI to less than 1 second. In many cases, the results appear almost instantly after you press the Enter Key.
