Using the Battery Management Studio (bqSTUDIO) tool to configure the bq34z100-G1 to HDQ mode, a write to the Control command [0x00] of [0x7C40] is required. To configure HDQ mode with bqSTUDIO: 1. Navigate to the Registers screen. HDQ mode is configured by writing data [0x7C40] to Control command [0x00]. 2. Click on the Control value field. 3. Write 0x7C40 into the text field and click OK. Because the change in communication protocol involves writing a flag for the new protocol to data flash, it takes about 200 ms to complete. During this time, communications are disabled. Once the command takes effect, the bqSTUDIO will no longer communicate with the gauge. 4. Close bqSTUDIO. Change communication connections from the gauge to the HDQ port of either the EV2300 or EV2400 device. Run bqSTUDIO. The bqSTUDIO auto-detection only works for devices that operate in I2C mode. 8.3.15.6.2 Converting to I2C Mode Texas Instruments ships the bq34z100-G1 device in I2C mode, which is required when updating data flash. However, this mode can be changed to HDQ mode if needed. To configure the device to use I2C mode when presently in the HDQ mode, a write to the Control command [0x00] of [0x29E7] is required. Use the Battery Management Studio (bqSTUDIO) tool, as follows: 1. Click on the Control value field. Write [0x29E7] in the text field and click OK. Once the command takes effect, bqSTUDIO will no longer communicate with the gauge. 2. Close bqSTUDIO. Change communication connections from the gauge to the I2C port of either the EV2300 or EV2400 device. Run bqSTUDIO. 这两段是在BQ34Z100-G1 上面看到的,BQ34Z100 是不是也可以使用?
