Hi,
Can anyone please help me with a library for Maxim's One Wire DS2788 Battery Gauge??
Or some information on how I could modify an existing 1-wire library, to work with the DS2788.
Thank you very much!
I can only suggest a good look at the data sheet which describes its one wire addressing .I’ve not found anyone using this with an Arduino from a search.
What is the project - there maybe other ways to do what you want??
From what a brief look shows, you would need a few parameters to set it up for a specific battery to get any reasonable values out of it .
Someone may be along with a better answer , but outlining what you are wanting to do would be useful to others
I looked through the datasheet, but I need some help to understant it. I have always used libraries with I2C, SPI and 1-wire devices, I don`t really know how it works.
I am trying to make a RF fishing boat controller and I chose the DS2788 because I wanted a better representation for the state of charge, than what you get by measuring the voltage of the battery (the DS2788 is a standalone battery gauge, it has 5 led drivers to show the SoC)
It would be nice if I could get more information from the DS2788 that just led representation.

Hello
I know it's not the same device, but it might be a start.
There is or a was library for DS2438
Joe Bechter and Philip Anderson published some articles on these devices.
A company called Embedded Data Systems do a lot of work with 1-wire devices and have a very good knowledge base of articles.
I know it is extra expense, but if you want to get started and get some confidence, the Maxim 1-wire USB stick will get you going with data fairly quickly.
Personally, to do the same task, I might start with an XBee that has plenty of analogues and digitals and is well supported by Digi. I regularly use them for battery voltage monitoring
