Hi all,
New to forum but have a general conversion question.
I am currently reading and sending a text file in CSV format to my Arduino Duemilanove. The Arduino is then outputting it via an HC-05 Bluetooth module to an Android app serial program.
The text file consists of the following data: 1.012,2.012,3.014,4.055,5.064,6.024
My current sketch has the ability to convert the text to a number if the number was a basic integer. How would I convert it to display the entire decimal (float)? I attempted to use the double function and float but have not succeeded. Any suggestions?
Here is my current code:
#include <SoftwareSerial.h>
SoftwareSerial mySerial(10, 11); // RX, TX
void setup() // run once, when the sketch starts
{
Serial.begin(9600);
mySerial.begin(9600); // set up Serial library at 9600 bps
}
void loop() // run over and over again
{
byte byteRead;
/* check if data has been sent from the computer: */
if (Serial.available()) {
/* read the most recent byte */
byteRead = Serial.read();
//You have to subtract '0' from the read Byte to convert from text to a number.
byteRead=byteRead-'0';
// Serial.println(byteRead);
mySerial.println(byteRead);
delay(50);
}
}
Here is my current output:
