How Do I Add Libraries To Energia?

[gettingbored 0]

So I installed Energia on my Mac, and even though the launchpad isn't listed under the serial ports I can still upload to it for some reason. However when I installed the program it didn't come with a Servo library. So I went to https://github.com/energia/Energia and downloaded the Servo library, poped open the contents of of the Energia program and stuck it with the other libraries. When I try to compile it though I get this error:

 

/Applications/Energia.app/Contents/Resources/Java/hardware/msp430/libraries/Servo/Servo.cpp:45:27: fatal error: avr/interrupt.h: No such file or directory
compilation terminated.

 

So basically, How do I add libraries to Energia?

Servo lib has not been ported to msp430 yet hence it was not included in the release. A enhancement request (https://github.com/energia/Energia/issues/69) has been files. pbrier, one of the project members, is working on it.

Once it has been ported a pull request will show up in that ticket. The library will show up in hardware/msp430/libraries once we pull it into master.

Ok that sounds good to me.

Hi,

 

I've met the same problem.

Is the servo library available finally ?

 

optionnally, I can make a one, but I don't want to make something if someone else is already doing it...

maybe it won't be the best one, but I was able to make my stuf move...

Servo lib has been ported and will be part of the next release slated for this week.

If you can't wait then you can get it here: https://github.com/energia/Energia/tree ... ries/Servo

Generally speaking, here's the procedure to add a library to Energia:

 

Define the folder for the sketchbook: menu Energia > Preferences > Sketchbook Location

eg. ~/Documents/Energia or /users/name/Documents/Energia

thanks !

I just replaced my own servo management by the use of the servo lib, and it works perfectly...

I am trying to use the Servo library but am getting a compile error:

core.a(TimerSerial.cpp.o): In function `TimerSerial__TxIsr':
C:\energia-0101E0008\hardware\msp430\cores\msp430/TimerSerial.cpp:202: multiple definition of `__isr_9'
Servo\Servo.cpp.o:C:\energia-0101E0008\hardware\msp430\libraries\Servo/Servo.cpp:87: first defined here
collect2: ld returned 1 exit status

 

Am I doing something wrong?

 

Here is my code:

//get a number from Serial and move a servo to that position (no error/limit checking implemented yet)
#include 
#define baudrate 9600
#define servoPin P1_4

int inByte = 0;  // incoming serial byte
char inData[3];  // serial input array (buffer)
int index = 0;


Servo myservo;  // create servo object to control a servo

void setup(){
 Serial.begin(baudrate);
 myservo.attach(servoPin);
}

void loop(){
 if (Serial.available() > 0) {
   inByte = Serial.read();
   inData[index] = inByte;
   index++;
   if (index > 2 || inByte == 10 || inByte == 13){ //buffer is full or we got a charage return or linefeed
     inData[index] = '\0'; //Null terminate the string
     Serial.println(inData);
     myservo.write(atoi(inData));         // sets the servo position according to the scaled value 
     delay(15);                           // waits for the servo to get there
     index = 0;
   }
 }
}

Your Servo.h and TImerSerial both want to use the same Timer interrupt. Which chip are you using? I'm guessing the g2452 or g2231. You will have to use the g2553 if you want to use both Serial and something that uses the Timer interrupt.

[bcarroll 2]

I am using the g2452. Any way to work around this limitation?

[Rickta59 589]

Not without a deeper understanding of the hardware. The easiest solution is to get an msp430g2553 chip if you want to use simple code.

[bcarroll 2]

I found an example that uses a servo and serial with the g2211, however the code doesn't compile in Energia.

 

Here is the error I get:

sketch_aug29a.cpp: In function 'void Timer_A1()':

sketch_aug29a.cpp:265:14: error: 'TAIV_TACCR1' was not declared in this scope

 

...was getting an error about main needing to return an int, so I changed the code to

int main(void)

instead of

void main(void)

which fixed that issue...

error: avr/interrupt.h: No such file or directory

 

Is there a avr subdirectory in the core?

[Rickta59 589]

Anything code that uses #include "avr/something*" isn't going to work with the msp430 Eenergia. avr is used for the atmel avr chips.

exactly!!
