一 概述

SC7A20 是一款高精度 12bit 數(shù)字三軸加速度傳感器芯片，內(nèi)置功能更豐富，功耗更低，體積更小，測(cè)量更精確。芯片通過(guò) I2C/SPI 接口與 MCU 通信，加速度測(cè)量數(shù)據(jù)以中斷方式或查詢方式獲取。INT1 和 INT2 中斷管腳提供多種內(nèi)部自動(dòng)檢測(cè)的中斷信號(hào)，適應(yīng)多種運(yùn)動(dòng)檢測(cè)場(chǎng)合，中斷源包括 6D/4D 方向檢測(cè)中斷信號(hào)、自由落體檢測(cè)中斷信號(hào)、睡眠和喚醒檢測(cè)中斷信號(hào)、單擊和雙擊檢測(cè)中斷信號(hào)。芯片內(nèi)置高精度校準(zhǔn)模塊，對(duì)傳感器的失調(diào)誤差和增益誤差進(jìn)行精確補(bǔ)償?！?G、±4G、±8G 和±16G 四種可調(diào)整的全量程測(cè)量范圍，靈活測(cè)量外部加速度，輸出數(shù)據(jù)率 1HZ 和 400HZ 間可選。芯片內(nèi)置自測(cè)試功能允許客戶系統(tǒng)測(cè)試時(shí)檢測(cè)系統(tǒng)功能，省去復(fù)雜的轉(zhuǎn)臺(tái)測(cè)試。芯片內(nèi)置產(chǎn)品傾斜校準(zhǔn)功能，對(duì)貼片和板卡安裝導(dǎo)致的傾斜進(jìn)行補(bǔ)償，不占系統(tǒng)資源，系統(tǒng)文件升級(jí)不影響傳感器參數(shù)。

二 工作模式

三種工作模式：正常模式（Normal mode）、掉電模式（Power Down）、低功耗模式（Lowpower），正常模式能保證更高的三軸輸出數(shù)據(jù)精度，低功耗模式能減少電流消耗。根據(jù) SC7660/SC7A20 規(guī)格書(shū)，XYZ 三軸的數(shù)據(jù)輸出速率（ODR）、XYZ 三軸的數(shù)據(jù)使能控制（Xen、Yen、Zen）及工作模式的選擇（Operating Modes）可通過(guò)寄存器 CTRL_REG1(20h)和寄存器 CTRL_REG4(23h)的 HR 來(lái)控制實(shí)現(xiàn)設(shè)置，如表 1、表 2 所示。

正常模式（Normal）

在此模式下，能保證更好的數(shù)據(jù)采樣精度，XYZ 三軸的數(shù)據(jù)可按照設(shè)置好的 ODR（數(shù)據(jù)更新率）周期性的輸出三軸數(shù)據(jù)寄存器。

掉電模式（Power Down）

在此模式下，除了 IIC 和 SPI 外所有的內(nèi)部模塊都被關(guān)閉以節(jié)省功耗，所有寄存器之前配置過(guò)的參數(shù)數(shù)據(jù)都被保存，而三軸輸出的數(shù)據(jù)寄存器的數(shù)據(jù)不再更新，仍維持上一次正常工作時(shí)采樣的數(shù)據(jù)。

低功耗（Low Power）模式

此模式的主要特點(diǎn)是功耗低，數(shù)據(jù)輸出情況和正常模式一致，三軸數(shù)據(jù)可按照設(shè)置好的ODR 周期性地輸出三軸數(shù)據(jù)。

三 三軸數(shù)據(jù)讀取操作

3.1 查詢狀態(tài)寄存器 STATUS 并讀取數(shù)據(jù)

當(dāng)有 X、Y、Z 軸有數(shù)據(jù)更新時(shí)，對(duì)應(yīng)狀態(tài)標(biāo)識(shí)寄存器 STATUS_REG(27h)的 ZYXDA、ZDA、YDA、XDA 位會(huì)自動(dòng)置 1，此時(shí)可直接讀取三軸數(shù)據(jù)寄存器 OUT_X_L(28H)、OUT_X_H(29H)、OUT_Y_L(2AH)、OUT_Y_H(2BH)、OUT_Z_L(2CH)、OUT_Z_H(2DH)，以上寄存器全部讀取操作完成后，狀態(tài)標(biāo)識(shí)寄存器 STATUS_REG 的 ZYXDA、ZDA、YDA、XDA 位才能自動(dòng)清 0。若在數(shù)據(jù)讀取前，數(shù)據(jù)發(fā)生再次更新，上次數(shù)據(jù)會(huì)被自動(dòng)覆蓋，且此時(shí) STATUS_REG 的 ZYXOR、ZOR、YOR、XOR 會(huì)自動(dòng)置 1，而讀完三軸數(shù)據(jù)寄存器內(nèi)容后會(huì)自動(dòng)清 0。若 CTRL_REG4(23h)的 BDU 位是置 0 的，數(shù)據(jù)會(huì)不斷更新，上述狀態(tài)標(biāo)志變化情況仍然會(huì)發(fā)生。

3.2 查詢 DataReady(DRY)信號(hào)并讀取數(shù)據(jù)

通過(guò)配置相應(yīng)的中斷寄存器，可以將 STATUS_REG(27h)狀態(tài)寄存器的 ZYXDA 位通過(guò)INT1 腳反映。具體配置方法為：將 CTRL_REG3(22H)的 I1_DRDY1 置 1，并通過(guò)配置CTRL_REG6(25H)中的 H_LACTIVE 位來(lái)選擇 INT 腳的極性（高電平有效或者是低電平有效）。當(dāng)設(shè)置為高電平有效時(shí)（H_LACTIVE=0），三軸有新數(shù)據(jù)更新則 INT1 腳會(huì)自動(dòng)升為高電平，此時(shí)完成三軸數(shù)據(jù)讀操作后，ZYXDA，ZDA，YDA，XDA 位會(huì)自動(dòng)清 0，同時(shí) INT1引腳自動(dòng)降為低電平。相反，當(dāng)設(shè)置為高電平有效時(shí)（H_LACTIVE=1），三軸有新數(shù)據(jù)更新則 INT1 腳會(huì)自動(dòng)降為低電平，此時(shí)完成三軸數(shù)據(jù)讀操作后，ZYXDA，ZDA，YDA，XDA位會(huì)自動(dòng)清 0，同時(shí) INT1 引腳自動(dòng)升為高電平。

3.3 BDU 功能

如果主機(jī)（MCU）讀三軸數(shù)據(jù)寄存器內(nèi)容的速度較慢，并且讀寫(xiě)速度無(wú)法和 DRDY 信號(hào)或者狀態(tài)寄存器標(biāo)志位的更新速度同步，強(qiáng)烈建議一定要將寄存器 CRTL_REG4（23H）的最高位 BDU 置 1。通過(guò)該方法可以保證讀取的三軸輸出數(shù)據(jù)（OUT_X_L~OUT_Z_H；0x28-0x2D）是同一時(shí)刻，即某一個(gè)運(yùn)動(dòng)狀態(tài)下的數(shù)據(jù)值。將 BDU 置 1 是為了使三軸數(shù)據(jù)不能自動(dòng)連續(xù)更新，直至某軸高位和低位數(shù)據(jù)都被讀取，才會(huì)有最新數(shù)據(jù)更新到該寄存器中。

歡迎同學(xué)們走進(jìn)AmazIOT知識(shí)庫(kù)的世界！

這里是為物聯(lián)網(wǎng)人構(gòu)建的技術(shù)應(yīng)用百科，以便幫助你更快更簡(jiǎn)單的開(kāi)發(fā)物聯(lián)網(wǎng)產(chǎn)品。

Cellular IoT Wiki初心：

在我們長(zhǎng)期投身于蜂窩物聯(lián)網(wǎng) ODM/OEM 解決方案的實(shí)踐過(guò)程中，一直被物聯(lián)網(wǎng)技術(shù)碎片化與產(chǎn)業(yè)資源碎片化的問(wèn)題所困擾。從產(chǎn)品定義、芯片選型，到軟硬件研發(fā)和測(cè)試，物聯(lián)網(wǎng)技術(shù)的碎片化以及產(chǎn)業(yè)資源的碎片化，始終對(duì)團(tuán)隊(duì)的產(chǎn)品開(kāi)發(fā)交付質(zhì)量和效率形成制約。為了減少因物聯(lián)網(wǎng)碎片化而帶來(lái)的重復(fù)開(kāi)發(fā)工作，我們著手對(duì)物聯(lián)網(wǎng)開(kāi)發(fā)中高頻應(yīng)用的技術(shù)知識(shí)進(jìn)行沉淀管理，并基于 Bloom OS 搭建了不同平臺(tái)的 RTOS 應(yīng)用生態(tài)。后來(lái)我們發(fā)現(xiàn)，很多物聯(lián)網(wǎng)產(chǎn)品開(kāi)發(fā)團(tuán)隊(duì)都面臨著相似的困擾，于是，我們決定向全體物聯(lián)網(wǎng)行業(yè)開(kāi)發(fā)者開(kāi)放奇跡物聯(lián)內(nèi)部沉淀的應(yīng)用技術(shù)知識(shí)庫(kù) Wiki，期望能為更多物聯(lián)網(wǎng)產(chǎn)品開(kāi)發(fā)者減輕一些重復(fù)造輪子的負(fù)擔(dān)。

Cellular IoT Wiki沉淀的技術(shù)內(nèi)容方向如下：

奇跡物聯(lián)的業(yè)務(wù)服務(wù)范圍：基于自研的NB-IoT、Cat1、Cat4等物聯(lián)網(wǎng)模組，為客戶物聯(lián)網(wǎng)ODM/OEM解決方案服務(wù)。我們的研發(fā)技術(shù)中心在石家莊，PCBA生產(chǎn)基地分布在深圳、石家莊、北京三個(gè)工廠，滿足不同區(qū)域&不同量產(chǎn)規(guī)模&不同產(chǎn)品開(kāi)發(fā)階段的生產(chǎn)制造任務(wù)。跟傳統(tǒng)PCBA工廠最大的區(qū)別是我們只服務(wù)物聯(lián)網(wǎng)行業(yè)客戶。

連接我們，和10000+物聯(lián)網(wǎng)開(kāi)發(fā)者一起 降低技術(shù)和成本門(mén)檻

讓蜂窩物聯(lián)網(wǎng)應(yīng)用更簡(jiǎn)單~~

哈哈你終于滑到最重要的模塊了，

千萬(wàn)不！要！劃！走！忍住沖動(dòng)！~
