Instead, I use shorthand code to use the OR operator to compare TCCR1B with a bitmask containing a ‘1’ at the correct location for the CS10 and CS11 bits. Any other bits on the TCCR1B register ...

His project lets you play simple algorithms as audio using AVR microcontrollers. Now the code work for this is very simple, but he hardware implementation is where things get interesting.

Microchip has created an AVR microcontroller series with 12Mbit/s USB 2.0 and code protection. “As the next generation of Microchip 8-bit MCUs to integrate USB connectivity, the AVR DU family is ...
