46  Products / Arduino Yún / Re: Where can I find out about programming the Linino side of a Yun on: February 09, 2014, 06:28:48 am
Quote
For example, can you only access it using Wifi, or can you open a Linino terminal over a USB connection?

You can open a connection via LAN or or WIFI
I am a Windows user, so I use Putty to connect but there are similar programs for Unix.
When you have made the connection you will feel at home since you are used to Unix.

The preferred language seems to be Python and PHP, and for databases SQLite or MySQL.

The Yun has an SDcard slot, can that be used as a "hard disk" to store Linux software?

Yes and it is recommended to do so, as the flash ram has limited write cycles.

Quote
I haven't bought a Raspberry PI because I don't have a TV and, in any case, I already have a Linux computer. The Yun looks like it might be a better package of Linux and I/O. But if the Linux side is very limited I will continue to work just with my Uno or Mega.

I use the same technique with my Raspberry Pi.
The difference is that on the RPI you have acses to the GPIO from Unix, on the Yon  you can only access the GPIO from the onboard Arduino Leonardo. (They are conected threough the Serial)

The connection between the two sides is through the Bridge Library

remove bootleader and flash again and use as arduino???

I am not sure I understand the question, but  you can burn a bootloader to your breadboard atmgega 328p-pu .

When you have done that it will be similar to the one sitting on your Arduino.

TCCR is regsiter in AVR

It is a very vague question, but my guess is that the answer is yes.

For example changing the pwm frequnce on an Arduino Uno could be done like this by setting the bits in register TCCR0A


Code:
int led = 13;           // the pin that the LED is attached to
int brightness = 0;    // how bright the LED is
int fadeAmount = 5;    // how many points to fade the LED by

void setup()  {
  //  To use Fast PWM on Timer 0Write this line in the setup function
  TCCR0A = _BV(COM0A1) | _BV(COM0B1) | _BV(WGM01) | _BV(WGM00);
TCCR0B = _BV(CS00);   
 pinMode(led,OUTPUT);
}

void loop()  {
  analogWrite(led, brightness);    
  brightness = brightness + fadeAmount;
  if (brightness == 0 || brightness == 255) {
    fadeAmount = -fadeAmount ;
  }    
  delay(30);                            
}

multiple definition of `TinyDebugKnockBangParserClass::process()'

I think you have more than one copy of the TinyISP installed.

TinyISP is a sketch and should be in your sketcfolder and TinydebugKnockBang  is a library and should be in your library folder.

Maybe this will be helpfull

You could take a look at Jack Christensens sleep code for the ATtiny85.

I have used it with this core without issues:

This cheet sheet might be useful if you are using the core (or files) found here https://code.google.com/p/arduino-tiny/

Something like this ?

Although I think it only connects to the programming pins.

I have used this servo library with both Attiny85 and 2313 and different servos without any issues

Are you sure ? I found this information on the official page http://playground.arduino.cc/Learning/WhatAdapter

That is about powering an Arduino (and similar)
The Arduino Yun do not have an onboard 5 V regulator, so for this you need a regulated 5V supply

Quote
Because I guess Yun need an antenna for the wifi ?

That would depend of the range you are expexting. I have not had any issues with range aprox. 5 meter through a concrete wall without antenna

You can  use your Arduino as serial/USB converter:
Connect a jumperwire from reset to ground on the Arduino, and connect the outputpin from your RPI  to TX (pin 1) on the arduino (labeled TX->1).

Be sure to connect the Grounds !
