I have project which among others involves a battery monitor for my lead acid batteries in my boat. I've searched for a solution with wide dynamic range for measuring current (mA to 100 A) and I found this nice piece TI BQ2018 ( http://www.ti.com/product/bq2018#technicaldocuments) that would be perfect for my needs.
However, it uses a less used proprietary communicating protocol (HDQ - http://www.ti.com/lit/an/slva101/slva101.pdf) and I can't find an existing Library for it. I'm an Arduino newbie and my programming skills haven't been used since the 80s, so I see this as a big challenge.
Anyone out there that has code for this? If not, I'm happy to get some guidance how to do it. Could I instead of starting from scratch change an existing Library (I2C, 1-wire etc)? Which one?
The BQ2018 seems to be a very good sensor for battery monitoring, maybe there are someone else that are interested in a wide dynamic range current sensor and get it to work with Arduino?
