Hello ! :)
Im a student in engineering, my project is to develop a directive speaker based on a ultrasonic piezo array.
The audio signal should be modulated with a sine carrier (AM, DSB). The carrier frequency is around 40khz.
So, I thinking of using sigma studio to do this task.
My school suggests the use of a PIC18F57Q43 (Which is not a properly DSP, but I can try)
My questions are:
- Can I use Sigma Studio to code this PIC, (which is not in the list of proposed DSPs), and How?
- If not, can I extract the algo from Sigma to implement it into the PiC ?
- If I use a regular DSP like ADAU1701, I saw that the DAC has a limited sampling frequency of 192khz max. Which is a little bit low for my ultrasonic application (40khz output). Is there alternatives DSP références with a higher sampling frequency output ? (That can be use on Sigma of course)
Last question, is there a way to ‘scope’ the output signal inside Sigma studio software to see the result of my modulation before implement it into DSP ? Or manually scope the signal from a port of my Pc ?
It’s a lot of question, but your responses could really help me !
Thanks you :)
