LunaAVR no longer free for commercial use.

Well, the author worked hard for this and now, that LunaAVR got the deserved attention, he must get his reward. Nothing wrong with this. Especially that the price is right for a professional with a lot of contracts.

What it remains for us, the "freeloaders"? A full featured LunaAVR, without restrictions for anything non-commercial. And that is still amazing in a world where all other commercial compilers/languages have ridiculous restrictions for non-commercial zone.

I still have the old stable version with a permissive license, but that means almost nothing, as I always want the latest, full featured version of  LunaAVR. Guys, even in this form, I really believe that is worth to download it, as long as there are still no limitations.

CNC-ing gears with Inkscape and MakerCAM

For CNC 2.5d operations you can use also free software as Inkscape and MakerCAM. Fast and easy. Thanks +drez20001

Wiring 1.0 is now on Build 101

But only for Mac and Windows. Linux is still on hold... waiting from 28 October 2014 ... Not many changes, but a very important one: avr-gcc 4.7.3. This will assure at least a more compact code.

The IDE comes with the possibility to display a schematic (as a PNG image) for every project so the user can have a better general "picture" about the project. And I like the IDE colors much more than those of the Arduino IDE.

Alternatives in programming the AVR microcontrollers

As a long time PIC programmer, spoiled by the bit support in, I think, all the compilers available, free or not, going to AVRs it was quite a shock to see what "enormities" I had to write to assign a value to a pin using the features provided by the avr-gcc compiler.

By example, in a code of a graphic LCD library, to set or clear the "chip select" pin, you had to write:


#define GLCD_CMD_PORT   PORTA        // Command Output Register
#define GLCD_CSEL1      0x03        // CS1 Bit Number
#define GLCD_CSEL2      0x04        // CS2 Bit Number

GLCD_CMD_PORT |= 0x01 << GLCD_CSEL1; // select chip 1
GLCD_CMD_PORT &= ~(0x01 << GLCD_CSEL2); // deselect chip 2


MCEDIT has JAL colored syntax

For the guys who don't know yet (I didn't knew until recently), the Midnight Commander (a superb console file manager like Norton COmmander) editor come with colored syntax for the JAL language. With a file that can be edited, for those who don't like some of the colors.

stickyBUG

Hi guys! Do you know or remember Firewing? It is an Arduino like board based on PIC18F's, PIC24 and PIC32 microcontrollers, accompanied by an excellent, free VB.NET compiler.
