3. FR8016HA芯片 power_off调用后功耗未达到规格书标称

FR8016HA芯片 power_off调用后功耗未达到规格书标称

  • Z

    官方最新ble_simple_peripheral例程上拓展功能，长按触发如下接口
    //power off
    wdt_stop();
    pmu_set_pin_pull(GPIO_PORT_A,1<<GPIO_BIT_6,true);
    pmu_set_pin_to_PMU(GPIO_PORT_A,GPIO_PA6);
    pmu_port_wakeup_func_set(GPIO_PA6);
    wait_power_off = 0;
    system_power_off(false);
    关机前是8mA多，关机后是2点多mA，没有达到规格书标称规格<3.5uA
    程序在system_power_off是否需要对pin做一些其他关机前操作嘛

    @zhang-haifeng pmu_set_pin_to_PMU(GPIO_PORT_A, 0xFF);
    pmu_set_pin_to_PMU(GPIO_PORT_B, 0xFF);
    pmu_set_pin_to_PMU(GPIO_PORT_C, 0xFF);
    pmu_set_pin_to_PMU(GPIO_PORT_D, 0xFF);将io交给pmu再试试，尽量用未改动的例程测这个
