Tôi đang tạo một cảm biến không dây bằng Attiny85. Tôi muốn gửi dữ liệu đến một arduino uno, vì vậy tôi đã mua bộ liên kết rf 315 mhz từ spark fun. Vì Attiny85 không có TX, tôi đã quyết định sử dụng thư viện Manchester tuy nhiên nó sẽ không được biên dịch trên Attiny85.
Tôi đã làm theo các bước từ blog này: http://mchr3k-arduino.blogspot.mx/2012/01/wless-sensor-node-part-2.html?showTHER=1338749638806#c853067277980266192
Đây là mã tôi đang sử dụng:
#include <WProgram.h> //otherwise it says it can't find Arduino.h
#include <Manchester.h> //include the library to comunicate
#define TxPin 2 //the pin that is used to send data
int sensorPin = 4;
int ledPin = 3;
int count = 50;
void setup(){
pinMode (ledPin, OUTPUT);
man.workAround1MhzTinyCore(); //add this in order for transmitter to work with 1Mhz Attiny85/84
man.setupTransmit(TxPin, MAN_1200); //set transimt pin
}
void loop(){
if (count == 50){
digitalWrite (ledPin, HIGH);
count = 0;
}
int data = analogRead(sensorPin);
man.transmit(data); //transmits and reads the data
delay (100);
count ++;
}
Đây là thông báo lỗi:
