The EEPROM library is just a thin wrapper around avr-libc so it should work but could be large.

is there any way to solve this issue? 

can I write the code that correspond to analogReference() directly in the Arduino sketch?

Thanks in advance

No need. After you make the minor corrections in the wiring.h it will work. Will be fixed in version 0.19

This is very strange. I am using version 18. The same code can be compiled for Attint85, but it does not work for Attiny13. That means that it is correctly spelled. The code that fails follows:

void setup() {
 analogReference(INTERNAL);
  // initialize the digital pin as an output.
  pinMode(led, OUTPUT);

 time = millis();
memooculto = EEPROM.read(0); delay(80);
 if (memooculto == 0) { maxmodereal = maxoculto;}
 else  {maxmodereal = maxmode;}
 
mode = EEPROM.read(1);
delay(80);
if (mode == 0) {mode = 1;}
if (mode > maxmodereal) {mode = maxmodereal;}
 }

I confirmed there is a problem with wiring.h. You need to uncomment analogReference() and change #define INTERNAL to something other then zero.

But unless you have another library, EEPROM functions won't work.

One question about using the internal voltage reference...

Is it implemented? in which pin?

Could you please show me how to use it in this Arduino core?

I am employing analogReference(INTERNAL) and I obtain the following error:

"AnalogReference was not declared...."

Please, if it is not implemented, I really need it for my project. and it must be the internal reference. 

Thanks in advance

The two references supported are ~1.1v and VIN. External reference is not supported in hardware.

Make sure analogReference is spelled right. Make sure the core is installed properly. Before version 0.18 analogReference was stub so make sure you update.

Internal clocks, being RC oscillators won't be too accurate.
They are not really stable over varying voltage either. Good enough for many cases though.

Yes that is correct PB0 and PB1 support PWM. PWM is fully implemented although the next version should improve PWM performance.

A bad hard disk wouldn't cause high fan speed. Perhaps your CPU cooler isn't seated well and it is overheating.

Can you check your temperatures?

Wow that is really lucky. I accidentally inserted an SRAM chip backwards and the PTC on the Arduino triggered and the voltage sagged to ~1V.

Amazingly the chip survived thanks to the fuse.

Atmega backwards? That could certainly cause high current usage.

To me, it sounds like excessive ripple is getting through. Can you try a different adapter?

What kind of CPU and how much RAM? Can you watch task manager while compiling?

Honestly it might be a melted atmega168. Are the TX/RX lights stuck on?

What kind of CPU and how much RAM do you have?

Sorry for the slow response.

Is the newest core called 017 ?

I downloaded from the link in the first post in this thread

No, the new version is 0.18.
