Opensprinkler on ESP8266

[Ray]

What’s the I2C address configured by your PCF8574 module? Note that it has 3 bits that you can use to set the I2C address (if I understand correctly, these would be the 3 yellow-colored jumpers on your module). It’s not clear to me whether you are following OS 3.0, 3.1 or 3.2 schematic. Only 3.0 uses PCF8574 (whereas 3.1 and 3.2 use PCF9555 16-channel IO expander). So assuming you are following 3.0 schematic, which is available here:
https://github.com/OpenSprinkler/OpenSprinkler-Hardware/tree/master/OS/3.0/AC_driver
it assumes that on the AC driver board, the three bits are A0=1 (high), A1=A2=0 (low). You need to set the jumpers correctly to match this address.

Hi, could someone help me with connecting PCF8574 to NodeMcu?
I compiled nad successfully uploaded a sketch to NodeMcu and all is fine except communication with PCFmodule – I set A0=1,A1=A2=0 and I can not change a state of SSR High level trigger… Should I change sth in source code?

[gadaka]

Hi, I bought PCF8574AP, connected it to NodeMcu with OLED display. Display works great but a module set High on all outputs and does not change after setting on in Openspringler. Could You help me?

[Ray]

I am not sure exactly which schematic you are following. As I said in my first reply: only version 3.0 board design uses PCF8574 — in fact, it uses one on the top level board, and one on the driver board. Revisions 3.1 and 3.2 do NOT use PCF8574, instead, they use a single PCA9555 IO expander chip. The reason is that PCA9555 is a 16-channel IO expander chip, while PCF8574 is 8-channel. So the original 3.0 design had to use 2x PCF8574, and later with PCA9555 it only needs one single IO expander chip. Also, PCA9555 uses totem output so can source much higher current into the traics on the driver board. PCA8574, on the other hand, uses weak pullup so cannot source high current (and for that reason OS 3.0 driver design had to use additional PNP transistors to provide high current).

[gadaka]

Thank You for the response.

I’m following 3.0 version schemtaic
I found in my country PCA9555 so I’ll try use it 🙂

[Ray]

If you follow OS 3.0 schematic, please note that there are two PCF8574 IO expanders, one on the top level (master controller), one on the bottom (AC-driver). The top level is set to I2C address 000, and bottom is 001. The bottom level controls solenoid drivers.

[gadaka]

Hi, I bought PCA9555 ad everything works great but I have one question – is it possible to control 12 sections using one PCA9555?

[Ray]

By “12 sections” did you mean 12 zones? The main controller can only control 8 zones. If you want to go beyond 8 zones, that’s what the expanders are for: each expander uses one additional PCA9555 to add 16 zones.

The reason the main controller only does 8 zones is that among the 16 IO pins of PCA9555, 8 are used for zone control, the other 8 are reserved for other purposes: including button 3, boost converter control on DC-powered OpenSprinkler etc.

[gadaka]

Yes, I mean 12 zones…
Ok, I undestand 🙂

Hello, actually I am unable to compile with errors like “‘uint8_t’ has not been declared” in SPIFFSdFat , I suppose due to a bad configuration. To configure and compile which files I have to edit? I heve to add defines in Config.h and change PROTO in Pins.h ? Are there exemples?
Thanks

Colleagues,

Was happily using opensprinkler in pi zero, but suddenly stopped working. Pi is dead and the issue is that I can not get a spare, so trying to move to ESP8266 HW . I do have 12F version. Downloaded the compiled file for ver 3.0 from here http://raysfiles.com/os_compiled_firmware/v3.0/ os_219_rev9.bin . Used the Express ESP flash tool, and followed this procedure https://www.allaboutcircuits.com/projects/flashing-the-ESP-01-firmware-to-SDK-v2.0.0-is-easier-now/
My question here is the starting memory. In that page it states 0xFB000. Is this correct?
The issue I am having is continues reboot, (btw, did not see any error on flashing the esp8266) and the blue led is flashing rapidly

2nd boot version : 1.4(b1)

Finally, at this point I do not have any HW attached to the ESP8266-12F . I would need the RTC + PCF8574. Is it possible this behavior because I do not have connected that HW?
Any idea what night be wrong?
Cheers,

Colleagues,

Still fighting….after another flashing attemps, I think I am moving(slowly…) . Now the ESP does not reboot and pop up as AP (SSID = OS_16ACD2) with 192.168.4.1, so I was able to connect and got the attached screen from opensprinkler(wifi config). To input SSID and pass , which I did and after that It register to my wifi, but can not get any response from the browser.
Any idea?

From the screenshot, it looks like the firmware is successfully uploaded. Depending on your WiFi network and the browser, after clicking on Connecting, it might not respond and may look as if it’s stuck. But what’s important is to watch the LCD screen: if it can connect to your WiFi router, then it will reboot itself (you may need to unplug and re-plug in power because ESP8266 has a well-known bug that triggers a stall if you reboot right after flashing the firmware. Power cycle it will fix the problem).

[zenonmb]

Thanks Ray .
I have already power cycle the ESP and I see no response for the browser.
At this time, I do not have display, nor expansion board (PC8574). Just the ESP8266 12F . Will connect the RTC module + PCF8574 and see what happens.
cheers,
martin

Well, having an OLED display connected would be tremendously helpful to see what’s going on. You can also turn on serial debugging and that way you can watch the output from serial. This would require you to compile the firmware. To turn on serial output, just uncomment this line:
https://github.com/OpenSprinkler/OpenSprinkler-Firmware/blob/master/defines.h#L27
and compile the firmware.

The latest firmware no longer requires an RTC — if an RTC doesn’t exist, it will fall back on NTP syncing. I don’t think it requires PCF8574 either: without PCF8574 it will by default assume this is an AC-powered opensprinkler.

[zenonmb]

Understand, but compiling the code seems challenging for me. Yes, you provided the instructions, but those are for linux and my Arduino IDE is on Windows and not sure if the procedure would be the same.
Thank you

[Ray]

You may not overthinking the difficulty of compiling the firmware. If you use Arduino IDE, you can simply install the required libraries in the IDE. Or, you can install virtualbox in Windows, and install linux in virtualbox.

[zenonmb]

Tried and as you suggested it was not difficult at all. Copied all files into the mainArduino directory , also added the 4 libraries and hit compile/upload(all within Arduino IDE).
No error, perfect clean. Same result as before, showed the WIFI as OS-ACD16, open browser, set my network credentials and after a minute did a reboot.
As before, it did not respond to the browser, so went to the defines.h files and uncommented the debug line.
Now when tried to compile, got errors stating that some libraries were not used . For example had with mqtt and also Ethernet(old libraries already in my arduino), so remove those and still getting the error below

This report would have more information with

Any suggestion?

Ray,

Commented out the lines and was able to compile it. This is what I get

[Ray]

All these messages look fine: it got NTP synced correctly, and seems to be able to connect to the weather server as well. If you know it’s IP address, you should be able to type that into a browser, or use the OpenSprinkler app, to access the controller.

[zenonmb]

Ray,

You were right. Now I do have the web and app running. Will get the HW, RTC and PCF8574 and put it to work. (not sure what happened before…)
Thank you very much for your support and regarding your system, there is no much to add . There are many messages in the forum stating the awsome product that you developed and opened to the community. Thank you
cheers,

martin

Is there anything that I can take a look?
