bq40Z50使用问题

Other Parts Discussed in Thread: BQSTUDIO, BQ28400, BQ40Z50

如图所示,我使用EV2300+bq40Z50(自己画的板子),发现bqstudio识别不到device,手动选择之后,发现有几个数值显示在Regieters上,但是可以看得出数值不太对,从抓波形来看,发现地址是0x16,而且还有ACk回应。地址是0x16?貌似文档上没有提及,后来我又换了一块板子,现象一样,排除了芯片的问题,问题究竟出在哪里呢???而且Sys Pres拉高拉低都没反应。但对于EV2300+bq28400通讯及设置是完全没问题的,smbus也有上拉。
