A weblog focused on interesting circuits, ideas, schematics and other information about microelectronics and microcontrollers.
ATMega SID emulator
This program tries to emulate the sound chip SID of the famous historical C64 Commodore computer (). The SID emulator includes all registers of the original SID, only minor functions are not implemented yet.
- 3 waveform generators
- 3 envelope generators with attack,decay, sustain, release
- waverforms: triangle, rectangle with variable pulse width, sawtooth, noise with variable frequency
- ring modulation
- 4 indicator LEDs for serial data transmission controll and status of waveform generator gates (v. 1.8)
ATMega SID could be controlled from Arduino by serial line (9600 Bd) too. This way it could work as standalone sound device. The SID may be controlled by a LabView program and the serial line of a PC.
