想請問兩塊感應器的程式合併問題 (已解決)
本帖最後由 小新手 於 2017-12-29 20:45 編輯我目前這裡有一個感應心跳後藍芽傳送的程式和gps定位的程序，我想將兩個結合在一起讓他可以同時運作，可是合併後，雖然心跳的部分沒有問題，藍芽也是都能順利連上手機並顯示心跳和GPS的訊息，不過gps部分總是一直沒收到訊號，可以請教各位大師我哪裡錯了嗎?:Q (用心跳程序當基底將gps寫上去)
心跳採用pluse sensor 藍芽採用hc-05 gps採用neo-6m
因為有點長如果看不下去的話請點這裡下程式碼QAQ : https://drive.google.com/open?id=1qcauSNLs1zAEQz1L2kD7qXPZSihbP--H

以上就是合好後有問題的程式....對不起有點長，希望大神們可以幫忙找一下錯誤在哪，現在這樣只能測心跳，GPS沒訊號，改了好久還是找不到問題所在 (用的是UNO或是Leonardo):Q 如果你是用 lenardo,
SoftwareSerial 的 RX 只能是以下接腳之一
8, 9, 10, 11, 14 (MISO), 15 (SCK), 16 (MOSI).
SoftwareSerial gpsSerial(12, 11); // RX, TX(gps腳位)
所以...程式對掉一下
接腳改一下試看看 本帖最後由 超新手 於 2017-12-28 20:19 編輯
另一個限制是
如果使用了兩個以上(含)的 softwareserial
一次只能一個 RX 作用
所以在呼叫 .available() 之前
必須先呼叫 .listen()
這個使用上需要點技巧
建議是把 serial 拿來用
這個是硬體的，限制較少
尤其是 Leonardo ，直接改成 serial1 即可 超新手 發表於 2017-12-28 20:02

所以把Serial拿來用的意思是將SoftwareSerial gpsSerial(12, 11); // RX, TX(gps腳位)改為SoftwareSerial Serial1(1, 0); // RX, TX(gps腳位)嗎？
還是說SoftwareSerial gpsSerial(1 0)就行了嗎？(抱歉這樣問，對這個還不很熟悉)
因為晚上了不方便去屋外測試GPS，所以只好先問腳位的問題 本帖最後由 超新手 於 2017-12-29 08:46 編輯
不是
如果你是用 Leonardo
1. 把SoftwareSerial gpsSerial(12, 11);這行拿掉
2. 把所有的 gpsSerial 改成 Serial1
3. 把 gps 接到 0 和 1
如果你是用 UNO
1.不改接腳
2.在 while(millis()-start <5000)加上 listen
gpsSerial.listen();
while(millis()-start <5000) {
.....
}
btSerial.listen();
但是uno 還是建議改用 serial ,然後 gps 接到 0和1
注意！！是 Serial, 和 Leonardo 不同
而且接到 0和1時，下載程式時可能先要拔 gps
否則不能下載

感謝超新手大大的幫助!!! 現在gps和心跳藍芽都能夠正常運行了!! 非常感謝QAQ
