arduino+AS608的使用教程

解決 Adafruit Fingerprint sensor enrollment

Did not find fingerprint sensor ? 的問題

器材的準(zhǔn)備

AS608光學(xué)指紋模塊

uno板子一個

杜邦線若干

usb轉(zhuǎn)ttl

接線

這個我就不說了小孩子都知道怎么接線

開始搭載AS608模塊

直接上代碼，不廢話

然后很多人到這一步就會報錯

Adafruit Fingerprint sensor enrollment Did not find fingerprint sensor :(

出現(xiàn)了這個報錯

不要緊,拿出早就準(zhǔn)備好的usb轉(zhuǎn)ttl然后將usb轉(zhuǎn)ttl和AS608連接,接口部分只用接VCC GND RX TX

第一步：將模塊的 Tx、Rx 連接到 USB 轉(zhuǎn)串口設(shè)備。（提示：開發(fā)板可使用板載的 CH340）。

第二步：在計算機設(shè)備管理器找到識別的串口號

第三步：打開模塊資料\2，配套軟件\指紋模塊測試上位機\指紋測試.exe，然后在上位機
選擇對應(yīng)串口號

第四步：點擊“確定”，通訊成功。

第五步：通訊成功之后可查看硬件信息、波特率等，可以點擊面板上按鈕等功能操作。

下面我們點擊“錄入指紋”按鈕，點擊后。并輸入 0為錄入指紋 ID。

第六步：點擊“確定”，軟件提示“請將手指平放在傳感器上”

第七步：按照提示將手指平放在傳感器上，等待圖像上傳， 所示。提示：
上傳時間稍微久一點。波特率越高速度越快，使用 USB 模塊測試則會更快。

第八步：第一次錄入圖像成功之后，軟件會提示“2.請將手指平放在傳感器上”表示第
二次錄入圖像。

第九步：當(dāng)兩次錄入圖像的指紋經(jīng)過對比匹配之后，如果一致的話指紋就錄入成功了。
錄入成功

第十步：前面操作是錄入了一個指紋，下面我們測試一下刷指紋（驗證指紋）。首先我
們點擊“搜索”

第十一步：點擊了搜索之后軟件提示“請將手指平放在傳感器上”

第十二步：按照提示將手指放在傳感器上錄入圖像成功之后，系統(tǒng)對比錄入圖像與指紋
庫，如果對比成功，則提示“找到相同手指，FingerID=88……”

提示：如果通訊不成功請檢查接線方式是否正確，正確方式是模塊 Tx、Rx 分別接到 USB
轉(zhuǎn)串口設(shè)備的 Rx、Tx。如果更改了模塊地址必須更改回默認(rèn) OxFFFFFFFF，同時口令也
必須是默認(rèn)值 0，這樣才能正常通訊！CH340 USB 轉(zhuǎn)串口的驅(qū)動程序在模塊資料\3，配套
軟件\CH340 驅(qū)動程序。

燒代碼部分

結(jié)束了上面的操作后你的AS608（相當(dāng)于激活了）能工作了

下載Adafruit-Fingerprint-Sensor-Library-master這個ardino的庫文件

1.在Arduino IDE中，轉(zhuǎn)到File > Examples > Adafruit Fingerprint Sensor Library > Enroll。

2.上傳代碼到Arduino開發(fā)板，并以9600的波特率打開串行監(jiān)視器。

3.這時您應(yīng)該輸入指紋的ID。由于這是您的第一個指紋，請在左上角輸入1，然后單擊Send按鈕。
大功告成

如果還有不會的伙伴在下方評論，我教你

創(chuàng)作不易，如果對你有幫助的還麻煩點個贊
