My code keeps giving me "'prizm' does not name a type"

Projects Programming

I use the following code and regardless of what I change I can't stop the "'prizm' does not name a type" message.

#include <PRIZM.h>

PRIZM prizm;
EXPANSION exc; 
void setup() {
  // put your setup code here, to run once:
prizm.PrizmBegin();
   prizm.setServoSpeed(1,25);
  prizm.setMotorInvert(1,1);
exc.controllerEnable(1);

}

void loop() {

}

prizm.setServoPosition(1,180); 
exc.setMotorDegree(1,15,20);
prizm.setMotorDegrees(50,180,50,180);
prizm.setServoPosition(1,0);

Did you notice loop() is empty?

Did you notice this code is outside of loop()? Actually that code is not in any function.

did you try

void loop() 
{

prizm.setServoPosition(1,180); 
exc.setMotorDegree(1,15,20);
prizm.setMotorDegrees(50,180,50,180);
prizm.setServoPosition(1,0);

}

?

I didn't want to put it in a loop, but you're right I didn't put it in any kind of function. I'll put it in a for(int x=0;x<=0;x++) style function and see if it works. thanks for your help.

why??

no, for loop is not a function. You can't organize code this way.

The C doesn't permit using the code outside the any function.

this

for (statement 1; statement 2; statement 3) {
  // code block to be executed
}

is not a function.

You could do

void loop() 
{
aFunction();

}

void aFunction()
{
prizm.setServoPosition(1,180); 
exc.setMotorDegree(1,15,20);
prizm.setMotorDegrees(50,180,50,180);
prizm.setServoPosition(1,0);

}

now the code should run and is not in loop()

that function should work for me. although now it's telling me

exc.setMotorDegree(1,15,20);

isn't a function even though its in the programming guide

Help us help you.

Where is the library for that?

Please point out where EXPANSION is included in the Prizm library,

im creating a robot to draw a circle using a marker help with an arm to lower and lift the arm up ive attacked a Rack and Pinion Linear Slide and used a motor to move the wheel because a part required for the servo isn't available to me. Since the robot still needs to drive I need a motor for each wheel and attached a MAX DC Motor Expansion Controller to the chassis however Ive never coded with this before.
Im sorry for not being helpful Im new to coding as a whole and have never used this forum before.

see post#9

the code I used for this came from an example code preinstalled on this computer
