Arduino晶片可以買Arduino mini來拆，就不用再灌燒錄程式進去了
注意:本Layout沒有設計燒錄程式的線路進去!
本layout圖的電路圖是參考Arduino官方提供所改成的
Layout圖
製作好後
3.開通晶片與上傳程式
準備USB to TTL燒錄器(CP2102
Arduino pro mini)
下載並安裝該燒錄器驅動程式
將燒錄器的Rx、Tx接再貼片的D8、D9上，燒錄器的3.3V接在EN上燒錄器的GND接在貼片的GND上
開通藍芽晶片
下載USR-TCP232-Test V1.4.exe程式
設定好序列埠，選擇燒錄器的port(COM?)
設定好胞率12500
HEX取消打勾
按Open
CMD輸入
$$$
S-,<你要設定的名子> <CR> /*設定BLE名字為<你要設定的名子>,<CR>是按Enter換行就可以了*/
SS,C0
<CR> /*是C零喔!*/
--- <CR>
/*每次輸入指令成功的話會回覆"CMD>AOK"*/
/*這樣基本上設定完成*/
上傳Arduino程式
將燒錄器的Rx、Tx接再貼片的Tx、Rx上，燒錄器的3.3V接在EN上燒錄器的GND接在貼片的GND上
打開Arduino
工具->開發粄->選擇Arduino Pro or Pro Mini
工具->序列埠->選擇燒錄器的port(COM?)
上傳程式碼
#define sensor_pin A1
#include <SoftwareSerial.h> // 引用程式庫
#define rxPin 8
#define txPin 9
SoftwareSerial BT(rxPin, txPin);
void setup()
Serial.begin(9600);
Serial.println("BT is ready!");
pinMode(rxPin,INPUT);
pinMode(txPin,OUTPUT);
BT.begin(115200);
}
void loop()
{
int
sensor_value = analogRead(sensor_pin); // 讀取FSR
double val = sensor_value
*3.3/1024;
Serial.println(val);
BT.print(val);
BT.print("\n");
delay(100);
}
4.完成
貼片操作
有線連電腦操作:
將燒錄器的Rx、Tx接再貼片的Tx、Rx上，燒錄器的3.3V接在EN上燒錄器的GND接在貼片的GND上
打開Arduino
工具->開發粄->選擇Arduino Pro or Pro Mini
工具->序列埠->選擇燒錄器的port(COM?)
看數據呈現
工具->序列埠監控視窗
看數據圖的呈現
工具->序列繪圖家
無線連手機操作:
將直流電源3.3V正極接在貼片的EN上、直流電源負極接在GND上
(電池(3.3V~12V)或是燒錄器皆可)
打開手機APP BLE Scanner
選擇該貼片名稱的connect
選COSTOM SERVICE
點 CUSTOM CHARACTERISTIC 的 I圈圈便可以看到及時數值
