I have made the PCB of the ESP32 Oscilloscope, a very nice project.
The display screen is working, the push buttons are working and the pull down menus but i do not have a oscilloscope signal.
I think it is caused by the i2s module where is says: "//TODO i2s_read_bytes is deprecated."
I have searched and read articles about the i2s but my knowledge is zero so no good luck.
It looks like there is a line (or lines) missing in the code.
