Unable to set time and date on High Precision RTC module

March_Castle · March 19, 2021, 9:13pm

I’m trying to create a height datalogger using a Seeeduino V4.2(ATMega328P) to host a Grove High Precision RTC (to timestamp the barometer data), Grove High Precision Barometer (to give a barometric reading, which can be converted to a height value) and an SD Card Shield (to save the data)

I am trying to find a sketch which will allow me to set the time and date, but every one I have tried so far either fails to recognise the chip, or appears to set the time, but only when the sketch is running - i.e when it is checked later, the clock is no longer set.

I have tried another clock chip, as I thought the first one may be faulty, but the replacement behaves the same. I have checked the voltage from the clock battery, and the battery is functioning normally.

I have run a I2C Scan, and the chip is being detected on 0x51 (as it should be)

I will focus on one sketch at first, as it will become complicated if I mention more than one (although I have tried several sketches made for this purpose, all of them unsuccessful).

In this example, I will use the sketch created by lambor, which is attributed to SeeedStudio, and is called ‘PCF85063TP_RTC’. The code is below, followed by the error message below that.

exit status 1

‘class DS1307’ has no member named ‘GetTime’; did you mean ‘setTime’?

This report would have more information with
“Show verbose output during compilation”
option enabled in File -> Preferences.

I have tried using the suggested change, but this just creates further error messages.

Thank you for your help, March.

Reload and try this given steps again-
Click the Set the time automatically toggle to the off position.
The time and date settings window with the Set time automatically toggle highlighted.

Set time and date to current and click Change.
The Change time and date window.

System date and time will be changed.
