I am trying to just get the thing talking but can’t seem to get any sample code to work.
here is the code I am trying to use"#include <OneWire.h>
// DS18S20 Temperature chip i/o
OneWire ds(10); // on pin 10
void setup(void) {
// initialize inputs/outputs
// start serial port
Serial.begin(9600);
}
void loop(void) {
byte i;
byte present = 0;
byte data[12];
byte addr[8];
if ( !ds.search(addr)) {
Serial.print("No more addresses.\n");
ds.reset_search();
return;
}
Serial.print("R=");
for( i = 0; i < 8; i++) {
Serial.print(addr*, HEX);*
- Serial.print(" ");*
- }*
- if ( OneWire::crc8( addr, 7) != addr[7]) {*
- Serial.print("CRC is not valid!\n");*
- return;*
- }*
- if ( addr[0] == 0x10) {*
- Serial.print("Device is a DS18S20 family device.\n");*
- }*
- else if ( addr[0] == 0x28) {*
- Serial.print("Device is a DS18B20 family device.\n");*
- }*
- else {*
- Serial.print("Device family is not recognized: 0x");*
- Serial.println(addr[0],HEX);*
- return;*
- }*
- ds.reset();*
- ds.select(addr);*
- ds.write(0x44,1); // start conversion, with parasite power on at the end*
- delay(1000); // maybe 750ms is enough, maybe not*
- // we might do a ds.depower() here, but the reset will take care of it.*
- present = ds.reset();*
- ds.select(addr); *
- ds.write(0xBE); // Read Scratchpad*
- Serial.print("P=");*
- Serial.print(present,HEX);*
- Serial.print(" ");*
- for ( i = 0; i < 9; i++) { // we need 9 bytes*
_ data = ds.read();_
_ Serial.print(data*, HEX);
Serial.print(" ");
}
Serial.print(" CRC=");
Serial.print( OneWire::crc8( data, 8), HEX);
Serial.println();
}*
Then I get these error msg,
sketch_dec27e:4: error: 'OneWire' does not name a type
sketch_dec27e.ino: In function 'void loop()':
sketch_dec27e:18: error: 'ds' was not declared in this scope
sketch_dec27e:30: error: 'OneWire' has not been declared
sketch_dec27e:47: error: 'ds' was not declared in this scope
sketch_dec27e:67: error: 'OneWire' has not been declared
The device is commected to pin 10 and 5volts from the ardunio. The Ardunio seems to be still running the first program I loaded to it.
Thank you for the help
