README
README.mdEngine Data Logger - Engine Data
This project has been developed using Automake and Makefile setup from: https://github.com/sudar/Arduino-Makefile
Sleepy Pi 2 needs to have software power jumper enabled if programming from the Pi. i2cset -y 1 0x24 0xFD Turn it off with: i2cset -y 1 0x24 0xFF
It's not strictly necessary, but Arduino-Makefile includes a script to reset the Arduino. It would need to be setup to set pin 22 of the RPi's GPIO high for about 1/3 of a second. Alternatively, https://github.com/SpellFoundry/avrdude-rpi provides a patched avrdude that handles this for you. This is the approach I have setup here. The Makefile points to a special avr_tools directory that contains this patched version. None of this is necessary if you are willing to manually hit the reset button whenever you try to upload code.

Questions
How big is the EngineData PCB?
It measures 109.5 × 119.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the EngineData use?
100 parts, built around the TJA1051T, LMR33630ADDA, EL817 and TXB0104PW. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the EngineData KiCad files?
From the techie66/EngineDataLogger-EngineData repository on GitHub, at the commit this page was made from: the board is hardware/EngineData.kicad_pcb and its schematic hardware/5V-LMR33630.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the EngineData design in my own project?
Its repository publishes it under the GPL-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
