ESP8266 ready

A project log for OBD2 Fuel Consumption Gauge

Picked up an STM32F103 micro, an ILI9341 and a ELM327 OBD BT dongle clone and off it goes!!!

I finally got a new layout ready and the communication "API" defined.

I was aiming for a structure with an ID, Value and checksum in binary format but for now, and to make debugging easier I made a simple API with all ASCII values: <ID>,<space>,<float><\n>.

This way I can enter a serial console and set the values manually and check if everything is working ok.

Now I have to get the STM32 code to send the values accordingly to this API.

P.S. I haven't been able to do it yet but I'm going to test the OBD comunication above the 90Km/h mark with the VAGCOM software running on the PC. If it works than it's something buggy on the code, if not than I might have to rethink this whole thing...
