bqEvaluation Software Autocycling for bq34z110

Other Parts Discussed in Thread: BQ34Z110

Hi,

I am trying to use the Autocycling feature of the bqEvaluation software for bq34z110 in relaxation mode.

I am currently using the I2C bus as communication channel and hence my configuration requires I2C-VOUT and HDQ as the IO pins for the autocycling feature. However, under the autocycle menu -> 2 pins, I see enable load "I2C VOUT" and enable charger "I2C SDA"


No matter how I clicked the charger option, the HDQ never toggles.

I tried the solution as posted in http://e2e.ti.com/support/power_management/battery_management/f/180/p/302533/1055856.aspx by editing the bq34z110_0_04.ini and adding the lines

[AutoCycle]
ChgPin=2

but it does not work.

Anybody knows why ?

    I found the problem. I was editing the incorrect .ini file. The .ini file that I was modifying was the one inside the root installation folder. However, the correct .ini file that should be modified is located under:

    C:\Users\<YOURUSERNAME>\AppData\Local\VirtualStore\Program Files (x86)\Texas Instruments\bq Evaluation Software\bq34z110<revNo>.ini


    In the .ini file, place/edit the two lines:

    [AutoCycle]
    ChgPin=2


    After that, the bq software will correctly control the HDQ pin
