A weblog focused on interesting circuits, ideas, schematics and other information about microelectronics and microcontrollers.
Generate real-time VGA signal + music with ATmega
An amazing demonstration of the power of the slightly overclocked ATmega88 (video included in the article).
Linus Akesson made the Craft demo. AVR Atmega88 microcontroller is clocked at 20MHz, it generates 45 full VGA display lines at almost 60Hz frame rate. Sound is generated during VGA horizontal blanking periods, gives a sampling rate of 31496kHz. Sound player is capable to play four sound channels. All is programmed in pure assembly language for best performance. Just: Enjoy!
