Other Parts Discussed in Thread: EV2400
We have been using bqeasy successfully for years to load our .DFI file into bq20z45R1 through the EV2300, configure to our liking, calibrate the current and enable the gauging. We stuck with the only tool we could get to work. We automated the keystrokes and mouse clicks so are tied into the setup. Now with a transition to Windows 7, from XP, (yeah late right?) there is trouble in river city. Most of our operations work, including reading all the chip registers,
But writing the SMB command 00 with a word of 0006 with the intention of turning on both the charge and discharge FETs fails in the Windows 7 PC when it works fine in the old XP machine. Also the Pack Current Calibration, in the Calibration screen of bqeasy, fails to perform the calibration. We take the same hardware to the old machine and all is good.
We think there may just be a command timing difference between the PCs that could cause this. We have tried the latest EV2300 drivers and notice they make the EV2300 a HID device instead of loading the T!bq80xx driver as before. We cannot figure out how to exorcise the HID driver from the PC to try the ol TIbq80xx driver. And going to a fresh install on another XP machine has proven troublesome as well. How does one remove the HID drivers for the EV2300 from the PC? The driver store folder is locked.
We have tried a EV2400, with the same results. We can access the chip, read registers, load the .dfi, and enable. But calibration constants will not update during the pack current cal. and we cannot get the FETs to turn on "manually" with the command 00 of 0006.
Help!, before the old PC dies and we are SOL.
