电池监控问题

Other Parts Discussed in Thread: TPS62730, CC2541

你好,我将keyfob原代码中的P0_7口改成P1.6口控制TPS67232

#if defined ( DC_DC_P0_7 )
// Enable stack to toggle bypass control on TPS62730 (DC/DC converter)
HCI_EXT_MapPmIoPortCmd( HCI_EXT_PM_IO_PORT_P1, HCI_EXT_PM_IO_PORT_PIN6 );
#endif // defined ( DC_DC_P0_7 )

但是发现测出的电池电量是25%,也就是测电压是tps67232是处于工作模式的,这是为什么呢?

上面这个函数有一句解释是“The GPIO output will be High on Wake, and Low upon entering Sleep.”也就是说这个函数会控制tps67232工作,降低功耗,实际测试功耗是降了,但测出的电压时25%左右,我觉得是我测电压时tps67232还处于工作模式,测的还是2.2V那个电压,而不是外部的3V电压,希望YAN,VIKI可以帮忙看看,搞了几天都没头绪。。。
