So i had this program and i am trying to get it to work but it keeps saying Arduino: 1.6.7 (Windows 7), Board: "Arduino/Genuino Uno"
a function-definition is not allowed here before '{' token
my program is this :
int startstring = 0; // recognition of beginning of new string
int charcount = 0; // keeps track of total chars on screen
#include <LiquidCrystal.h> // import the LiquidCrystal Library
LiquidCrystal lcd(12, 11, 5, 4, 3, 2);
void setup() {
Serial.begin(9600); // opens serial port, sets data rate to 9600 bps
lcd.begin(16,2); // Initialize the LCD size 16x2. Change if using a larger LCD
lcd.setCursor(0,0); // Set cursor position to top left corner
pinMode(13, OUTPUT);
}
void loop() {
char incomingByte = 0; // for incoming serial data
if (Serial.available() > 0) { // Check for incoming Serial Data
digitalWrite(13, HIGH);
incomingByte = Serial.read();
if ((incomingByte == '~') && (startstring == 1)){ // Check for the closing '~' to end the printing of serial data
startstring = 0; // Set the printing to off
delay(5000); // Wait 5 seconds
lcd.clear(); // Wipe the screen
charcount = 0; // reset the character count to 0
lcd.setCursor(0,0); // reset the cursor to 0,0
}
if (startstring == 1){ // check if the string has begun if first '~' has been read
if (charcount <= 30){ // check if charcount is under or equal to 30
lcd.print(incomingByte); // Print the current byte in the serial
charcount = charcount++; // Increment the charcount by 1 yes I know it's awkward
}
}
if (charcount == 31){ // if the charcount is equal to 31 aka the screen is full
delay(500);
lcd.clear(); // clear the screen
lcd.setCursor(0,0); // set cursor to 0,0
lcd.print(incomingByte); // continue printing data
charcount = 1; // set charcount back to 1
}
if (incomingByte == '~'){ // Check if byte is marker ~ to start the printing
startstring = 1; // start printing
}
}
digitalWrite(13, LOW);
delay(10); // 10ms delay for stability
}
Any idea what happened i really appreciate the help
