![]() ![]() util/delay.h provides a _delay_ms() call that should do the trick. We might as well look at the samples for inspiration.įirst thing we'll do, since we need to add some delay when toggling the LEDs, is use some of the handy functions from the avr-libc. To fix that, simply right click on the project, in the solution explorer, and in the Build tab, on the "Generate Files" line make sure the ".hex" checkbox is set (for both Release and Debug).Īrmed with the knowledge of where the LEDs and HWB button are connected ( PD5 and PD6 for the LEDs, PD7 for HWB), let's write us some code to blink the LEDs. One thing you'll notice when compiling a new project is that the default settings are not to generate a. AVR Studio will even create a source template for you, how nice! On the next screen, in the Device Family, select "megaAVR, 8-bit", and pick up AT90USB162 (or any other Atmel chip you might be using). ![]() Change the default Name to 'Blinky' and click OK. The Minimus USB, or any AT90USB162 based board don't seem to exist in the Atmel/User Boards lists, so don't bother trying to pick a template there. In AVR Studio, click "New Project" and use the "AVR GCC", "Empty AVR GCC Project" template (which should be selected by default). Creatively, I'm going to call it 'Blinky'. On the other hand, it should be possible to port the libusb 1.0 and commandline based dfu-programmer to Windows, to provide a flashing tool that integrates with AVR Studio.Īlrighty, let's create our first LED blinking app then. hex and still use Flip manually to transfer the files. Sadly, no Flip integration is provided yet, so we'll have to generate a. Installation takes a little while but is a no brainer. So off you go to download AVR Studio 5 (free, but registration required). ![]() We've come a long way from substandard proprietary toolchains. Now, Atmel did the smart thing here: They picked up the Visual Studio 2010 base from Microsoft which they wrapped around avr-gcc and avr-libc. You'll see plenty of posts mentioning the need to install WinAVR around, but with the latest toolchain from Atmel, it looks like a separate installation of WinAVR has become a thing of the past, and we won't actually need to install anything but latest official Atmel toolchain, which is called AVR Studio. Time to get our toolchain installed then. ![]()
