Arduino: 1023 or 1024

We have a thermistor connected to an Arduino through a voltage divider circuit. The voltage divider consists of the thermistor and a second fixed resistor.

Custom Arduino Driver for Battery Gas Gauging Device BQ28Z610

This is a driver for Arduino that provides functions to interface with the BQ28Z610 battery gas gauge device over I2C protocol. With this driver, you can operate the BQ28Z610 device via the serial port from your computer using Arduino.

Functions were implemented based on the documentation:

• Technical Reference Manual (c) Texas Instruments, Literature Number: SLUUA65E, https://www.ti.com/lit/ug/sluua65e/sluua65e.pdf

Not all functions described in the Technical Reference Manual were implemented, but most of them.

The driver also includes some additional service functions for more usability.

This simple program was developed to implement keyboard layout switching using just one key. It utilizes the win32api, thus it will only work on Windows systems. 

Texas Instruments Battery Gas Gauging Device BQ28Z610 JBL XTREME 2 Data Flash Content

This dump of Data Flash was made for the device after few years of active usage.

What Does the Texas Instruments BQ28Z610 Device Function "12.2.19 AltManufacturerAccess() 0x0028 Lifetime Data Reset" Do?

It only writes the following Data Flash values:

0x4280: (I2) [Lifetimes / Voltage / Cell 1 Max Voltage] = 0
0x4282: (I2) [Lifetimes / Voltage / Cell 2 Max Voltage] = 0
0x4284: (I2) [Lifetimes / Current / Max Charge Current] = 0
0x4286: (I2) [Lifetimes / Current / Max Discharge Current] = 0
0x4288: (I1) [Lifetimes / Temperature / Max Temp Cell] = -128
0x4289: (I1) [Lifetimes / Temperature / Min Temp Cell] = 127
