A Teensy 3.6-based logger and gauge for my 2014 Subaru STI.

This project is built as an Arduino sketch. I used Arduino 1.8.8, but later versions will likely work too. You will also need the Teensyduino add-on (https://www.pjrc.com/teensy/td_download.html), and the following libraries:
- My fork of ILI9341_t3: https://github.com/jasminpatry/ILI9341_t3
- My fork of Adafruit_GFX: https://github.com/jasminpatry/Adafruit-GFX-Library
- font_Exo-BoldItalic: https://github.com/FrankBoesing/fonts/tree/master/ofl/exo
This project was built using the following hardware:
- Teensy 3.6
- MC33660 K-line serial interface chip, SOP-8 package (datasheet); I purchased mine from eBay
- Custom PCB fabricated using the files in the KiCad/boostino.gerber directory (I used BasicPCB's ValueSpec option, which in 2020 cost me about $30 for 3 boards).
- HiLetgo ILI9341 2.8" SPI TFT LCD Display Touch Panel 240X320 with PCB 5V/3.3V STM32
- OBD-2 cable — the switch and DB9 connector in the linked cable aren't necessary (I snipped them off), but the DB9 connector was useful when prototyping.
- Innovate Motorsports (3877) LC-2 Digital Wideband Lambda Controller Kit with Bosch LSU 4.9 O2 Sensor (optional; only necessary for AFR display and logging)
- Molex Micro-Fit 3.0 plug for connecting to the LC-2 serial output (optional; only necessary for AFR display and logging)
- Elcoho 10 Pieces Plastic Waterproof Boxes Junction Case Compatible with Electronic Project 3.94 × 2.36 × 0.98 Inches, Black
- For the faceplate, I had faceplate.eps laser-cut by https://www.ponoko.com/ using:
- Acrylic - Two Color - Brushed Silver on Black
- 0.059 inches thick
- P1 - 7.126 inches long x 7.126 inches wide
- Miscellaneous cables, headers, resistors, capacitors, diodes, wires, screws & nuts, etc.
A previous version of this project used the Tactrix OpenPort 2.0 to communicate with the ECU. That version is available in the Tactrix branch.
