Allthough i have been mostly observing, reading and learning on this forum for the last months, i also have started to design, simulate and build my own wfc. Since i have a background in electronics and computer science i decided to base my system on a microchip PIC processor. I think that by using a micro processor you not only reduce the part count it also greatly improves the possibilities to test and debug your wfc since i am able to change parameters or even the entire configuration with in system programing in very little time from software instead of changing entire electronic circuits. I hope to show some early results soon ..... (why doesn't a day have more than 24 hours
)
That's great Sharky, looking forward for your results.
What is your solution for a PLL function in the controller with electronics and computer science background?
Are you clocking the PIC clock dynamically or do you use Software PLL (ADC/DAC) solution. Should be (0Hz - 20kHz) range.
My idea is to build a 12bit SPLL using a ADC or PULSE counter to generate GATED PULSE signal from the DAC on a STM32 SoC.
I don't know if a microcontroller could do 0.01Hz or 0.001Hz steps accuracy for resonance PULSE adjustments.
Maybe a FPGA chip could be handy?
It would be great if you also use a SPPL or have other solutions.
