![]() Architecture2 uses a dedicated microprocessor for waveform generation and a dedicated microprocessor for the user interface. Architecture1 uses a function generator type IC that normally interfaces with a microprocessor leaving the microprocessor free to handle the user interface. ![]() On my own I've considered two architectures (see attached jpg files). The waveform output doesn’t have to be locked to a PLL – but that type of stability would be preferred.Square Wave is fine – but need accurate duty cycle settings.Stable Waveform (glitch free during normal operation).What I wish to accomplish is to build a robust function generator, but before I begin coding like a madman I would first like to find an architecture. ![]() I have written limited code for both in C and assembly. However, I do not have any formal training or on the job training (or at home hobbyist training) in microprocessors such as the PIC or HC12. I've dabbled a bit with microprocessors and even taught an online course in microprocessor interfacing (which is concerned more with peripherals than coding). ![]()
