RTC example wont compile on Particle Photon

Need Help With My Project

Hello to all.

Trying to use the RTC example

Particle IDE gives Compile error
TimeLib.h: No such file or directory

Below is the error shown in Particle Web IDE:

Have you tried installing the Time library?

Pete.

Can’t see it being available @PeteKnight

WARNING :
For this example you’ll need Time keeping library:
GitHub - PaulStoffregen/Time: Time library for Arduino

This code is based on an example from the Time library:
https://github.com/PaulStoffregen/Time/blob/master/examples/TimeSerial/TimeSerial.ino

Sorry @PeteKnight.
I’m lost!

That lib isn’t available through Particle webide.
Should I download and add it as a. cpp. h
Does the code example remain the same?

6

No idea! Maybe a question for the Particle forum?

Pete.

Check this out for RTC on the Particle Photon.

https://docs.particle.io/reference/device-os/firmware/#time

8

Thanks for that @BianchiRider
But how would this help with the RTC example by Blynk?

9

I thought you wanted to get the time on your Particle Photon for your Blynk application. This is how I do it on my Photon that has Blynk. RTC is ‘built’ into the firmware of the Particle Photon.

10

I actually wanted to get the time from Blynk server.
That’s why I was trying to use the example first from Blynk.

11

Time library already installed?

12

Libraries are added through Particle Web ide.
The particular libs in the Blynk example can’t be added.
