BQ34Z100 setting DOD0

$
0
0

I have been using the BQ34Z100 on a recent application and I am struggling to get the fuel gauge to learn correctly. After discharge the OCVTAKEN flag eventually sets. At this point I want to send the IT ENABLE command, this is where I get stuck.

I am using V0.9.90 of the BQ Evaluation Software

In the I2C PRO tab I try to send the following:

  • I2C command '00'
  • Data block '0021'

I would expect this to set the VOK and QMAX flags, but nothing happens. Am I doing something wrong with how I send the IT ENABLE command?
