ADXL345_Library_for_arduino cn->一種簡單方便的驅(qū)動庫可以很好兼容arduino系列，更少的依賴方便移植到其他類型mcu，靈活配置寄存器 iicsensor ic傳感器，這里包括adx345驅(qū)動和一個aht10的驅(qū)動 意味著他不能以spi方式操作。以后會加以改進(jìn)。這個庫文件并不簡潔。但是可讀性非常高，主要彌補(bǔ)流行庫文件不能涵蓋的功能，例如低功耗，fifo。
低功耗進(jìn)入流程 配置auto sleep位為1，在第一次檢測靜止中斷時停止讀寫ADXL345_REG_INT_SOURCE寄存器，在INT引腳接收到中斷后讀取寄存器恢復(fù)正常運(yùn)行。意思是在休眠模式不要試圖與其通訊。不這樣做的后果會導(dǎo)致傳感器退出休眠模式后無法再次讀取中斷標(biāo)志位
AHT10AHTxx是來自中國的一種溫濕度傳感器 aht10 20 21 有各種封裝類型，aht10是初代版本，他價格在1——5rmb左右。這是一個ADXL345驅(qū)動的附帶產(chǎn)物。 部分示例如下

- Interrput.map_overrun = INT_PIN1;
- acc.set_interrput(&Interrput);
- delay(100);
- Fifo_InitTypeDef fio;
- fio.self_test = 0; //自測
- fio.spi = 0; //spi模式選擇，1三線，0四線
- fio.int_invert = INT_INVERT_HIGH; //中斷高低電平
- fio.full_res =1; //1全分辨率，0 10位分辨
- fio.justify = 0; //對齊
- fio.range = ADXL345_RANGE_16_G; //量程
- fio.fifo_mode =FIFO_BYPASS; //旁路
- fio.trigger = INT_PIN1; //觸發(fā)中斷1
- fio.samples =FIFO_SAMPLES_31; //8
- acc.set_fifo_mode(&fio);
- delay(100);
