sprinkler_pi on a Raspberry PI B+

[guptihabib]

Have attempted to setup the application on my PI B+ with an external relay. Loaded wiringPI, get how they map to GPIO pins. Need some help with mapping my Zones to pins?

My wiringPI output looks like this;

I've only got 8 zones using GPIO 21 - 25 & 27 - 29.

Cheers, Mike

the wiringpi pin numbers correspond to the zones in sprinklerpi: http://projects.drogon.net/raspberry-pi/wiringpi/pins/

Nick,

I got that, what I'm struggling with is how to correlate a zone to a particular pin?

Cheers, Mike

That is what I was saying. Zone 1 is wiringPi pin 1 for example. On Jun 6, 2016 2:32 PM, "guptihabib" notifications@github.com wrote:

Ah, ok. So can I simply change the max_zones variable to increase the number of zones?

Yes, to a limit though due to the AVR code memory size. I know for sure it works with up to 15 zones.

So, in the case of a new raspberrypi B+, how do I map the high end pins to a zone? The number of usable CPIO pins exceed 15? That's where I don't get it.

There is no pin mapping. Wiring Pi Pin 1 is Zone 1, pin 2 is zone 2 and so on. Unless you go in the code and change it. To my knowledge the program hasn't been tested with over 15 zones.
