Hi,
I'm attempting to communicate to a bq2083-V1P3 fuel gauge.
I have installed bq2083-bq2085 EVSW Install v2p5 and am using a EV2300 on a Windows XP machine. The SCL/SDA lines on the battery are pulled up to 3.3V. The software does not display any telemetry; it states "Target Board Not Responding". I have also tested communication when using a EV2400 and an EV2200.
I've confirmed that the fuel gauge is powered (3.3V provided from AFE) and have also confirmed that the fuel gauge is operating (CLKOUT from FG is a clean 32khz square wave). I have confirmed the fuel gauge is not held in reset (MRST is low).
I have not achieved successful communication with this fuel gauge. What other elements should I be investigating or using?
