/**

功耗：

闲置模式功耗为250+ua

低功耗模式1，若前后脚地磁开启，板子地磁不开启，且不读取数据，功耗为330+ua ； 若只是读取前后脚地磁，则功耗为450+ua， 若读取前后脚地磁后再reset + 配置，则功耗为700+ua

低功耗模式2，若只开启后脚地磁，板子地磁不开启，且不读取数据，功耗为300+ua ； 若只是读取后脚地磁，则功耗为370-390+ua, 若读取后脚地磁后再reset + 配置， 则功耗为500+ua

//以上低功耗测试都是没开六轴，只开地磁的情况

游戏模式spi_lsm，8.5ma

游戏模式i2c_lsm，8.7ma

前脚地磁供电关闭，后脚地磁供电开启，因为sda（标准输出）线共用，当sda输出0时，前脚地磁的供电IO和sda导通，导致短路，功耗为11ma，且后脚地磁数据异常。
所以通过开关电源来复位地磁失败！！！

低功耗模式3，只开启后脚地磁，板子地磁不开启，读取完地磁和低功耗加速度后（都是用SPI读取），在睡眠前重新配置（不reset）后脚地磁，功耗为370 - 400ua

PS：低功耗模式3中，读取低功耗加速度用SPI时，速度为152us，用模拟I2C读取，速度为457us，由于时间变长，功耗为400 - 430ua

更新时间：2021-10-12：

低功耗模式4，更改了结构板，将IMU移到前脚，同时I2C的SCL公用，SDA独立，取消每次读取地磁后reset+配置。
这时，低功耗模式（没跑算法）功耗为：350-380ua 、 闲置模式功耗为：180-270ua 、 游戏模式功耗为：12-13ma，若再扣去小板上的六轴挂起功耗(22ua)+地磁挂起功耗(9ua)的31ua，
则各个模式功耗为：低功耗模式（没跑算法）功耗为：319-349ua 、 闲置模式功耗为：149-239ua 、 游戏模式功耗为：12-13ma

更新时间：2021-11-25：
IMU的FIFO读取地磁，会出现重复现象，目前猜测是IMU的HZ与地磁的HZ不同步，地磁是100HZ，IMU是104HZ，其次，地磁无出现数据0的现象。

更新时间：2021-11-29：
版本：1.9.1
板子本身功耗：12-14ua
测试，低功耗FIFO功耗（没跑日常计步算法）：537-549ua
测试，低功耗FIFO功耗（没跑日常计步算法），不读取IMUFIFO数据：454-464ua
测试，单纯设置外设，不跑IMU线程，功耗：453-462ua
测试，单纯设置外设（断电后脚外设供电,虽然其本身就是设置完后就挂起），不跑IMU线程，功耗：433-444ua
测试，断电前后脚外设，不跑IMU线程，功耗：175-224ua
测试，开启维持一个串口，功耗增加为：473ua
结论：
低功耗FIFO模式（100ms唤醒）下，不跑日常计步算法，总功耗为：537-549ua
外设功耗为：后脚地磁挂起（20ua）+前脚外设的IMU_104HZ_acc_timestamp_sensorhub_slv0123（128ua）+前脚外设地磁100HZ（150ua）
线程功耗为：IMU线程（84ua->读取IMU的FIFO数据10组，耗时1.1~1.2ms）+bat线程（5ua）+其余线程和广播（170ua）

游戏模式下（没焊接单线灯）功耗为：
设备直接进入：7.4ma
链接右鞋后，手机下发游戏指令，进入：8.5-8.6ma

更新时间：2022-3-7
版本：2.1

待机模式（不穿鞋）功耗：270ua ~ 467ua

正常模式（穿鞋）功耗：570ua ~ 630u

游戏模式功耗：
