home 1.2.2,关于降低功耗,有几个问题确认一下:
1.设置POWER_SAVING和RFD_RCVC_ALWAYS_ON to FALSE
2.按键轮询是不是比中断费电?
3.对下面几个参数设置有什么建议(终端需要接收数据)
-DPOLL_RATE=3000
-DQUEUED_POLL_RATE=100
-DRESPONSE_POLL_RATE=100
-DREJOIN_POLL_RATE=440
4.未用的IO如何设置为输入上拉或者输出,用哪个函数?在哪里设置?
Unused I/O pins should have a defined level and not be left floating. One way to do this is to leave the pin
unconnected and configure the pin as a general purpose I/O input with pull-up resistor. Alternatively the pin can be
configured as a general purpose I/O output
