Manipulating Registers in AVR Microcontrollers

This guide aims to explain what registers are, and how to work with them. It applies to miniMO and the Arduino IDE but also to microcontrollers in general, and will be most useful to you if you can understand basic programs and would like to modify the setup of the timers or other peripherals within the microcontroller, but can’t make clear sense of lines like ADMUX |= (1 << ADLAR);

miniMO multiplies

I received the PCBs last Friday and built a few MOs over the weekend. I’m very satisfied with how things turned out; the PCBs look sharp, I had no difficulties in soldering the components, and everything works correctly. I found I made a couple of errors with the design, but both have easy fixes and functionality isn’t compromised.More…
