St. Patrick’s Day is coming up and I thought it’s already time to update the original Valentine’s Day POV display with a new message and make use of the second PCB I had done at BatchPCB. Also, fortunately, John “smeezekitty” (the author of the Attiny13 core used for programming it in Arduino IDE) stopped by my blog and pointed out to an issue with the original firmware, which prompted me to take another hard look at it and the result has been a saving of whopping 20 or so bytes – it was just enough to fit the word “BEER” which, as I mentioned in the original post, we did not have any space in flash left for. Well, now we do and below is the new software Read the rest of this entry »
I can hear you screaming:”Not another LED blinker!” and yet here it is, packaged into yet another transparent Ferrero Rocher chocolate box, just like the first one. Why another ATtiny13 LED project? I needed to change the software to add a new feature and I had another box stashed away after Christmas – that alone should have been a reason enough Additionally, I have to admit right here that there will likely be one more post that includes an ATtiny13, LEDs and chocolates before I let it go (soon, I promise) and move onto more serious things, such as the DVD-CNC project that’s been languishing on and off my workbench for more than a year now.
That said, if you are still interested in programming ATtiny13 with the Arduino IDE to blink 12 Charlieplexed LEDs, respond to motion (shaking) and have the LED on/off sequence scripted in an orderly fashion rather than random or simply 1 through 12, then read on! Read the rest of this entry »
This is a quick follow up on an eariler post describing installation of Atmel AVRISP MKII programmer on a Ubuntu Linux computer. The original post was based on Ubuntu 10.10 and several small changes have sneaked up on us during the upgrade to Ubuntu 12.04
Here are the changes: Read the rest of this entry »
But you wouldn’t be using all of its great capabilities if you had to switch back to a text editor every time you needed to program a smaller Atmel chip, such as ATtiny13 for example. The engines behind the Arduino IDE – AVR-GCC compiler for C and C++ and avrdude – an in-system programming software for Atmel’s AVR series of micros – are already there and capable of coding for and programming the smaller chips, we just need to add a little bit of configuration magic to the Arduino IDE to be able to switch hardware freely without leaving your favorite Integrated Development Environment. Here is how: Read the rest of this entry »
