A breif overview of why I started working on D-DAQ and what it's designed to do:
Oh, watch it on youtube with annotations turned on please. I've included CC too.
The original Doniol gauge used a 128x128 pixel, OLED displays and a MSP430 MCU. It tapped into a stock/OE Bosch MAP (manifold absolute pressure) sensor with a range of 2.5 or 3 BAR. It optionally had a daughter board for connecting a K-type thermocouple. It was simple and elegant as it fit right over an unused portion of a MK IV Jetta's instrument cluster. After researching the hardware and beginning my dive into electronics, I was able to figure out which display driver and which interface was used to interact with it. About a year ago I had the opportunity to talk to the creator and he was kind enough to answer a few questions for me even though I was in the process of starting my own project inspired by his creation.
Anyhow, onto the details about D-DAQ, you'll soon can see that for just a *simple* boost gauge and data acquisition logger, there is quite a bit of complexity here. Shush all of you who say it's undue. As a general overview to the base system design I've kept the layout simple. Feel free to start reading after the break for the nitty gritty details.Read more »
Cool project. I have a GM TBI data acquisition project on my to do list for someday. :)
