Accelerometer

[ElliotCourant]

So I'm trying to implement the accelerometer, and i get several errors.

RobotDemo(void):
		myRobot(1, 2, 3, 4),	// these must be initialized in the same order
		leftstick(1),		// as they are declared above.
		rightstick(2),    	// as they are declared above.
		gyro(1,1),
		acc(I2C)
{

and it gives me this

C:/WindRiver/workspace/Final/MyRobot.cpp:34: error: expected primary-expression before ')' token

How do I implement the accelerometer?

Be patient. It was less than a half hour before your "bump".

Have you looked at the documentation for the ADXL345_I2C class? Is there anything you don't understand about it?

Which line is 34? What is I2C? A constant? A macro? Full source code would be helpful.

line 34 is "acc(I2C)"
That is a screenshot of just that part.


And yes I have looked at the documentation but it didn't really help me that much. It just told me that it needed a slot and a PID source. But because the accelerometer is connected to the I2C section I can't get it to work.

Here is the deceleration of "acc"



But it doesn't give me any errors there

Are you using the ADXL345? In which case you need to use the ADXL345_I2C class, not the Accelerometer class.

Again, what is I2C? A macro? A constant?

Quite correct.

In the code Elliot posted, I2C is undefined. That's why the compiler choked on it.

Elliot did not post his entire source code, there could be a constant or preprocessor definition above the class definition.
