TVout demo not compiling [Fixed]

Projects Programming
1

I've placed all the header files in the libraries folder but get the following errors:

In file included from C:\Users\Henry\Documents\Arduino\libraries\TVout\pollserial.cpp:28:
C:\Users\Henry\Documents\Arduino\libraries\TVout\/pollserial.h:46: error: conflicting return type specified for 'virtual void pollserial::write(uint8_t)'
C:\Program Files\Arduino\hardware\arduino\cores\arduino/Print.h:48: error:   overriding 'virtual size_t Print::write(uint8_t)'

Is this something stupid that I've (not) done (more than likely) or is it an error in the TVout code?

Also, how can I get to see ALL the tabs when some are off the RHS of the IDE screen? I can't find how to scroll through them.

How did you install the library ? (exactly how I mean. Explain everything you did from moment you downloaded it.

Goto Pollserial.h, on line 46 change virtual void to virtual size_t.
Also inside the function you need to return 0x01

When Arduino was upgraded to verison 1.0 the Print library was modified. Your library is a pre 1.0 version.

Thanks, pYro, but I'm not certain what you mean by

Here's the original code:

I think he means this

class pollserial : public Print {
	public:
		pt2Funct begin(long);
		void end();
		uint8_t available(void);
		int read(void);
		void flush(void);
		virtual size_t write(uint8_t);
		using Print::write; // pull in write(str) and write(buf, size) from Print
                return 0x01;
};

I think he means this

class pollserial : public Print {

public:
	pt2Funct begin(long);
	void end();
	uint8_t available(void);
	int read(void);
	void flush(void);
	virtual size_t write(uint8_t);
	using Print::write; // pull in write(str) and write(buf, size) from Print

return 0x01;
};

That causes even more errors!

Not quite, the class modification is fine, except for the return:

class pollserial : public Print {
public:
pt2Funct begin(long);
void end();
uint8_t available(void);
int read(void);
void flush(void);
virtual size_t write(uint8_t);
using Print::write; // pull in write(str) and write(buf, size) from Print
return 0x01;
};

In the location where the class functions are defined ( with code between {} ) you need to modify the function.

Maybe in pollserial.cpp there should be something that resembles the function below.

void pollserial::write(uint8_t){
  //some code
}

you need to modify it to look like:

size_t pollserial::write(uint8_t){
  //some code
  return 0x01;
}

Thanks very much, pYro
