Dear iwatake2222,
I built your code with success and connected up my ILI9341 display but I'm unable to see any display.
I tested my connections twice and I can see activity on the pico pins with my logic analyser.
I notice that on your connection picture you have pins GP0 and GP1 connected somewhere but they do not show in your wiring text page.
I also used your latest checkout.
Do you have any possible ideas I could also test?
If I was to send my uf2 file for you to load and it works on your setup, this would immediately point to my setup as a problem.
Thanks for a great project if I can get it to work.
Eric.

Hi, can you add some explanations? based on the video you're using a Raspberry Pi Pico, so your code should be in micropython; but the Github is not clear at all! which one is the main file? which files are mandatory?

Describe the bug
The system freeze happens after runnig the application for a while (10-20 seconds).

To Reproduce
Steps to reproduce the behavior:

1. Copy pj_adc_fft.uf2 to pico, and the application automatically starts
2. Keep it running for a while
3. The system freeze happens (It usually happens less than 10-20 seconds after start)
   Also, the freeze easily happens when displayed wave is huge (input void is huge) and it causes the processing time on core0 long

Expected behavior
The system keep running
