Ds1302.h No Such: File Or Directory

If this doesn't compile, uninstall the library completely and reinstall it from the menu. A Quick Note on Hardware Just a heads-up: fixing the library error gets you past compilation, but the DS1302 is an older 5V chip. If you're using a 3.3V board (ESP32, Raspberry Pi Pico), you'll need level shifters on the data pins. But that's a topic for another blog post! Summary | Error | Most Likely Fix | | :--- | :--- | | ds1302.h: No such file | Install library via Library Manager | | DS1302.h: No such file (after installing) | Check case sensitivity in #include | | Still failing | Manual ZIP install or restart IDE |

fatal error: ds1302.h: No such file or directory #include <ds1302.h> ^ compilation terminated. Don’t worry. This doesn’t mean your code is broken. It just means your computer can’t find the map to the library. Let’s fix it. The DS1302 is a popular real-time clock (RTC) chip. When you write #include <ds1302.h> , you are telling the compiler: “Go find the instructions for talking to that chip.” ds1302.h no such file or directory

Happy coding, and may your RTC always keep the correct time! If this doesn't compile, uninstall the library completely

If you’ve ever worked with an Arduino, ESP8266, or a standard AVR microcontroller (like the ATmega328P on an Uno), you’ve probably seen this red text of doom in your compiler output: But that's a topic for another blog post

If this compiles, the library is installed correctly. The problem is somewhere else in your original code (like a missing file or wrong path).

#include <DS1302.h> void setup() {} void loop() {}

lib_deps = msparks/DS1302 @ ^1.0.0 Then run pio run — PlatformIO will fetch the library automatically. Create a new, empty sketch and type only this:
