Platino Signal Generator Programmed Controller (130407-41)
Programmed ATmega1284P-PU microcontroller # 130407-1 for the project Experimenter's Function Generator, as published in Elektor Magazine edition January/February 2015.
This simple Platino-based Signal Generator is designed for not too demanding (hobbyist) applications. It is usable for applications like signal tracing, clocking of MCU circuits, audio filter & loudspeaker testing, tuning, etc.
A Signal generator device generates signals of different frequencies. The Platino Signal generator device uses the Elektor’s Platino board to design a real time, straight forward, non complicated design of the Signal generator. Inspired by Elektor’s AVR SDR project.
