The twenty-fifth meeting marks our third anniversary, and will feature a talk on writing embedded firmware and a panel discussion that will explore the future of open source hardware.
Writing firmware for the AVR: A Morse Code Beacon
In this talk we will look at a number of techniques for making the most of the miniscule MSP430 and ATTiny embedded microcontrollers. Explaining how to approach the task of developing software for constrained systems such as those with only a few hundred bytes of RAM or a few kilobytes of Flash. Predominantly writing in C and using Chris Swan’s Morse Code Beacon as an example, revealing why code needs to be structured in ways that may initially seem counter-intuitive or undesirable, as well as how the resources are used and allocated.
Such techniques are essential for getting almost any useful program to run in small systems, and when applied to slightly bigger machines such as the ATmega — found in platforms such as Arduino — they can allow really comprehensive programs to be executed successfully….
Panel discussion: The Future of Open Source Hardware
Interest in open source hardware continues to grow unabated and the movement has come a long way in the three years since our first meeting. However, could it ever provide opportunities on the same scale as those afforded by its much older and now well understood cousin, open source software? What are the barriers to growth? How are the intellectual property and economic considerations different to those of open source software? These are just some of the questions that we plan to explore as part of this panel discussion.
