我拿另外电池实际测试过了,EV2400也是支持的。但是提供的EVM不能通讯。
The fuel gauge is shipped in the I2C mode. TI provides tools to enable the HDQ peripheral.
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.
您好!
是在mouser.cn上买的,照理说应该不会有问题啊。就是说EVM 应该是不需要做任何改动,I2C和HDQ都能用才正常对吧? 刚我看也有人在问这个HDQ问题啊。看资料HDQ通讯是需要某种工具来enable的啊,不是直接和I2C共用的吧?
感谢您的帮助,谢谢!
