工程师你们好,我用的板子是rev:1.4,直接将例程pinShutdown下载到板子上,按键后使板子进入休眠,此时测试电流为2mA左右。请问:哪里有问题呢?是测电流接的引脚问题还是需在代码中修改设参数呢?
thanks!

通过板子的右下角的3.3v和GND供的电,跳线帽插的外部供电extern pwr,起初拔了上面gnd、5v、3.3v的跳线帽,已隔断和传感器芯片的电流;后面看文档,又拔掉了TMS和TCK,电流还是2mA左右,接线:就是从3.3v和GND供电串联了一个灵敏电流计。
休眠时,灯是不亮的。
可以参考rfWsnConcentrator和rfWsnNode例程。
The ConcentratorRadioTask handles the radio protocol. This sets up the EasyLink API and uses it to always wait for packets on a set frequency. When it receives a valid packet, it sends an ACK and then forwards it to the ConcentratorTask.
The NodeRadioTask handles the radio protocol. This sets up the EasyLink API and uses it to send new ADC values to the concentrator. After each sent packet it waits for an ACK packet back. If it does not get one, then it retries three times. If it did not receive an ACK by then, then it gives up.
