Send HDQ Screen
To configure a bq27742 fuel gauge into HDQ mode, navigate to the Send HDQ screen. It is possible that
all the screen options on the left are not visible depending on screen resolution. If needed scroll within the
left menu to access the Send HDQ link. Click on the "Change comm to HDQ8" button while having the
bq27742 fuel gauge connected to the EV2300 interface board via I2C. Clicking on the button causes a
message to appear indicating that the process is not reversible and to confirm if the actions are desired.
Also, it explains what to do once the HDQ mode has been activated.
但是EV2400界面我找了好久没有找到啊。
Unfortunately the bqstudio for the bq27742 does not have the one click button that puts the device into hdq. However, you can trick the system using bqstudio for another device. Here is how: -disconnect the gauge from the computer by disconnecting the usb cable to the computer -start bqstudio and select gauge, then select bq27541-g1. -now plug in the bq27742 gauge by connecting the usb cable back. -the bqstudio for the bq27541 will detect communication and you should be able to cllick the i2c to hdq button o n there and put the device into hdq mode.
