Adding a Real Time Clock while using Sprinklers_Pi #108

Closed wehix closed 5 years ago

wehix commented 6 years ago

Hi, After spending an hour trying to get my Real Time Clock DS1307 working with my RPi Zero W and Sprinklers_Pi I just realised BCM2 (SDA) and BCM3 (SCL) are used for Zones 8 and 9. My installation only uses up to Zone 6. Is there any way I can regain the use of those GPIO ports for SDA and SCL? Thanks, Bill H

Yes, in settings.h set NUM_ZONES to 6, then recompile/reinstall. Your settings should be fine to keep using but anything over 6 may disappear. Alternatively, you can edit the 2nd ZoneToIOMap (the one in the #else) in core.cpp and change the pins that conflict.

Hi Nick, Thanks for your quick reply ! I've gone with the easier option and edited core.cpp changing the line as you suggested. 8-->21 and 9-->22 however I still get 3.3v on both Pins 3 & 5, dropping to 0v when their respective Zone is on. Is there something I'm missing? Incidentally, after looking through the code files earlier I picked that would of been the line in core.cpp to edit, but needed confirmation. As a newbie to the world of Pi, I'm not quite up to compiling and reinstalling yet, is there much to it?

Regards, Bill H

I would make sure you reset your pi if you've run the old one as the pins were previously initialized.

How is a reset best achieved? Using hte reset options within Sprinklers_Pi or a reinstall?

Cheers, Bill

nhorvath commented 6 years ago

No i just mean restart the hardware (reboot). The other thing to check is make sure that you changed the right ZoneToIoMap. Also the Pi 0 might have different pinouts than the ones we are using which are based on the Pi 2/3... it might be another zone causing the issues. Sorry I can't be more specific I've never tried a Pi0.

Hi Nick, Many thanks for your help. Great product BTW ;-) As an alternative, how would I go about recompiling and installing settings.h? This is an unknown to me.

Kind regards, Bill H

nhorvath commented 6 years ago

Same as you did with core.cpp. The wiki has building instructions, follow the upgrade one.
