Compilation error for Arduino UNO used as an ISP to program the ATTiny85 chip

anon19092081 · March 28, 2022, 6:05pm

Good day folks. I do NOT know where to put this in a forum,and I have looked for the correct place, so please forgive my ignorance, if It shows.

I have been having this error, and I cannot seem to find the cure for it.
Here is the error code from the IDE -

Error compiling for board ATtiny25/45/85.

Now, Here is the code I am trying to compile. I had no issues before, and I seem to be missing something, but, I cannot make out where I went wrong with this. Am I correct in assuming that the error is in the "servo" header load?

Here is the code -

#include <Servo.h>







const int button = 2;                         // N.O. Pushbutton
const int sw_Normal_Direction = 1;            // left position of SPDT toggle switch
const int sw_Reverse_Direction = 0;           // right positiion of SPDT Toggle Switch
const int block_det = 4;


int pos;

Servo myservo;  // create servo object to control a servo
// twelve servo objects can be created on most boards




void setup() {
  
    
  
  myservo.attach(3);  // attaches the servo on pin 3 to the servo object

  pinMode(button, INPUT);                     // sets button to be in the input mode
  pinMode(sw_Normal_Direction, INPUT);        // switch normal setup
  pinMode(sw_Reverse_Direction, INPUT);       // switch Reverse setup
  pinMode(block_det, INPUT);
  
  myservo.write(60);                          // initialize starting servo position

  
}

void loop() {


  int button_State;
  int sw_Normal_Direction_State;
  int sw_Reverse_Direction_State;
  int block_det_state;
  
  block_det_state = digitalRead(block_det);
  button_State = digitalRead(button);
  sw_Normal_Direction_State = digitalRead(sw_Normal_Direction);
  sw_Reverse_Direction_State = digitalRead(sw_Reverse_Direction);
  
  digitalRead(button_State);
  digitalRead(sw_Normal_Direction_State);
  digitalRead(sw_Reverse_Direction_State);
  digitalRead(block_det_state);

  while(block_det_state == HIGH){
  


        if(sw_Normal_Direction_State == LOW  && button_State == LOW){

            for (pos = 60; pos <= 130; pos += 1) { // goes from 60 degrees to 130 degrees
            // in steps of 1 degree
            myservo.write(pos);              // tell servo to go to position in variable 'pos'
            delay(30);                       // waits 30ms for the servo to reach the position

            // digitalRead(sw_Normal_Direction_State);

                if(pos == 130){

                  myservo.write(pos);

                }              
                  
            }
            
        }



  
digitalRead(button_State);
digitalRead(sw_Normal_Direction_State);
digitalRead(sw_Reverse_Direction_State);



         if(sw_Reverse_Direction_State == LOW  && button_State == LOW){

            for (pos = 130; pos >= 50; pos -= 1) { // goes from 130 degrees to 60 degrees
                // in steps of 1 degree
                myservo.write(pos);              // tell servo to go to position in variable 'pos'
                delay(30);                       // waits 30ms for the servo to reach the position

                // digitalRead(sw_Reverse_Direction_State);
                
                if(pos == 60){

                  myservo.write(pos);

                }

            }
            
       }

   }

}

I am not even sure if I entered the code correctly to the forum, so, and constructive help there is also appreciated.

Thanks in advance for your help.

There is no timer/counter1

Were you compiling for the ATTiny85 then?

From this line of your output I can see you are using the old school "ATtiny Microcontrollers" boards platform:

The modern and more popular ATTinyCore boards platform does provide an ATtiny compatible Servo library. So you might give that a try instead if you want to control a Servo from an ATtiny85. Installation instructions are available here:

github.com

SpenceKonde/ATTinyCore/blob/OldMaster---DO-NOT-SUBMIT-PRs-here-Use-2.0.0-dev/Installation.md

Supported IDE versions
============
ATtinyCore (Universal) works with all versions of the official IDE (from arduino.cc ) from version 1.6.3 onwards. For boards manager installation, 1.6.4 or later is required. Due to serious bugs, 1.6.6, 1.6.7, 1.6.8, and 1.6.10 are not recommended. Version 1.8.9 is recommended.

Boards Manager Installation
============

This core can be installed using the boards manager. The boards manager URL is:

`http://drazzy.com/package_drazzy.com_index.json`

1. File->Preferences on a PC, or Arduino->Preferences on a Mac, enter the above URL in "Additional Boards Manager URLs
2. Tools -> Boards -> Boards Manager...
  *If using 1.6.6, close boards manager and re-open it (see below)
3. Select "ATTinyCore by Spence Konde" and click "Install".

Due to [a bug](https://github.com/arduino/Arduino/issues/3795) in 1.6.6 of the Arduino IDE, new boards manager entries are not visible the first time Boards Manager is opened after adding a new boards manager URL. If you are still using this version of the IDE, you should update. It is ancient.

Manual Installation
============

Thank you! I did install this one, and restarted the IDE. I will try again, and see what happens...

I will let you know shortly.

Thank you!

Perehama · March 28, 2022, 6:37pm

Servo.h doesn't check to see that you are running a ATTiny. But, the source it includes does and rules out the mcu so all the lines go undefined. Basically, the Servo library doesn't support ATTiny no matter what core you are using.

anon19092081 · March 28, 2022, 6:38pm

So using ATTiny85 is out of the question to use? I had boards already manufactured for its use....

Perehama · March 28, 2022, 6:39pm

using servo.h is out of the question. Using a 16-bit timer is out of the question.

anon19092081 · March 28, 2022, 6:42pm

What are my alternatives?

in0 · March 28, 2022, 6:44pm

As I already explained, ATTinyCore comes with a special version of the Servo library for the ATtiny microcontrollers:

Perehama · March 28, 2022, 6:49pm

From the error messages, the OP is not using this library. I am not a core expert, and I know SpenceKonde/ATTinyCore has lots of flags, so perhaps you could explain how to enable this library in his program.

Yes, that would be a big help... I have the library installed, and it does not use that library...

I sure would appreciate the knowledge on how to make it use this library. Thank you!

The first thing you need to do is make sure you have the ATTinyCore board selected. This is a "platform bundled library", which means it is only accessible when you are compiling for one of the boards of the platform.

So select Tools > Board > ATTinyCore > ATtiny25/45/85 (No bootloader) from the Arduino IDE menus.

There is another potential problem, as mentioned in the library description:

If the Servo library has been installed into /libraries, it will be used instead. It probably doesn't support the ATTinyCore devices. In this case, use Servo_ATTinyCore.h instead of Servo.h.

The library is the same, but DrAzzy made the header file name unique so that there will be no conflict with the standard Servo library you have installed here:

So you only need to change this line of your sketch:

to this:

#include <Servo_ATTinyCore.h>

There is some additional documentation about the library here:
