The best and easiest way is to use Arduino Library Manager. Search for RP2040_RTC, then select / install the latest version.
You can also use this link
Another way to install is to:
- Navigate to RP2040_RTC page.
- Download the latest release
RP2040_RTC-main.zip. - Extract the zip file to
RP2040_RTC-maindirectory - Copy whole
RP2040_RTC-mainfolder to Arduino libraries' directory such as~/Arduino/libraries/.
- Install VS Code
- Install PlatformIO
- Install RP2040_RTC library or RP2040_RTC library by using Library Manager. Search for RP2040_RTC in Platform.io Author's Libraries
- Please visit documentation for the other options and examples at Project Configuration File
If your application requires 2K+ HTML page, the current Ethernet library must be modified if you are using W5200/W5500 Ethernet shields. W5100 is not supported for 2K+ buffer. If you use boards requiring different CS/SS pin for W5x00 Ethernet shield, for example ESP32, ESP8266, nRF52, etc., you also have to modify the following libraries to be able to specify the CS/SS pin correctly.
To fix Ethernet library, just copy these following files into the Ethernet library directory to overwrite the old files:
To fix EthernetLarge library, just copy these following files into the EthernetLarge library directory to overwrite the old files:
To fix Ethernet2 library, just copy these following files into the Ethernet2 library directory to overwrite the old files:
To add UDP Multicast support, necessary for the UPnP_Generic library:
- To fix
Ethernet3 library, just copy these following files into theEthernet3 librarydirectory to overwrite the old files:
To be able to compile and run on nRF52 boards with ENC28J60 using UIPEthernet library, you have to copy these following files into the UIPEthernet utility directory to overwrite the old files:

If you get compilation errors, more often than not, you may need to install a newer version of the core for Arduino boards.
Sometimes, the library will only work if you update the board core to the latest version because I am using newly added functions.
- Using TimeLib instead of Time to avoid case-insensitive issue with Windows and MacOS.
- Add simple examples with manual time input
- Fix bug in display alarm time due to buggy
datetime_to_str()function
- Fix
library.propertiesto addmbed_nanoarchitecture for NANO_RP2040_CONNECT using Arduino-mbed RP2040 core
- Initial coding to support RP2040-based boards such as NANO_RP2040_CONNECT, RASPBERRY_PI_PICO, ADAFRUIT_FEATHER_RP2040 and GENERIC_RP2040 using Arduino-mbed RP2040 core or Earle Philhower's arduino-pico core.
Submit issues to: RP2040_RTC issues
- Search for bug and improvement.
- Basic RTC-wrapper library for RP2040-based boards, such as NANO_RP2040_CONNECT, RASPBERRY_PI_PICO, ADAFRUIT_FEATHER_RP2040 and GENERIC_RP2040, using Arduino-mbed RP2040 core or Earle Philhower's arduino-pico core.
- Add Version String
- Add Table of Contents
- Add simple examples with manual time input
Many thanks for everyone for bug reporting, new feature suggesting, testing and contributing to the development of this library.
- Thanks to kenb2054 to report bugs in Libraries updated to support new RP2040-based boards (RASPBERRY_PI_PICO, etc.) #43 leading to v1.0.4
