I copied a hardware spectrum analyzer, which works well by directly dragging the program. I hope to increase the software functionality of the spectrum analyzer, such as adjusting the amplifier's gain and high-voltage power supply through digital potentiometers. During the research process, I couldn't find a suitable LittleFS library in the Arduino library manager. I tried using the LittleFS_Mbed_RP2040 library, but it reported an error: 'FSInfo' was not declared in this scope. I think it's due to library incompatibility. Where can I obtain the LittleFS library? |

Using Arduino-Pico can compile. https://github.com/earlephilhower/arduino-pico/ To install Arduino-Pico, need to add a JSON file: https://github.com/earlephilhower/arduino-pico/releases/download/global/package_rp2040_index.json |
