Where I describe the process of developing code for the Microchip ATtiny13A, starting at the chip level.

This is a series of posts describing how to develop at the chip level using assembly language and C. In this series, I’ll be using a Microchip ATtiny13A, which is a minimal version of an ATmega328P, the microcontroller used in the Arduino Uno R3.

Introduction#

While the Arduino tool set, (both the Arduino IDE and Arduino software framework) are outstanding for quickly developing a working prototype, they do so with a combination of a graphical-user-interface (GUI), the C++ language and Arduino-only classes. This in itself, isn’t a problem, one can be quite efficient and productive using this approach.

This approach is an issue if you are at a university or job which expects a standards-based C language proficiency. It is also an issue, if your class or job, requires understanding how to use command-line-interface (CLI)-based tools. The C language, and not C++, is the basis of a significant number of embedded systems development.
