Stc-1000+

I took a look and there is a PIC 16F1829 that has double the flash space and 4x the RAM. Pin compatible.

What could we do with more memory ?

This has been asked and answered at least twice before, here and here.
Short answer: SMD component, badly located for replacement. No point in writing and testing code for something no one is gonna be able to do.
The STC is what it is (and it is good imho), but it's not gonna do everything. C'est la vie.

Ah... Yes... Alright... I must have already bumped the version before... Dang it.
Well, no backsies.... I'll just leave the 1.08 to be lost. Like leasure suit larry 4

I'm working on the revising the documentation, that will make it clearer I think. But the vanilla version has probe 2 stuff removed (hy2, tc2, Pb2). Which makes it less confusing if you never intend on adding a second probe.

Otherwise, the only change should be that SP has moved to the front of the Set menu (that + different layouts of eeprom for the different versions, makes for the need to update eeprom data as well).

Edit: Turns out you could tag a previous commit and create a release from it, so I created the release for v1.08 (which added the communication and 433MHz radio firmwares).

Just to clarify once more(sorry). Is sketch generator generated(webpage) *.ino's the same as Master code?
I am not sure if I understand the link between Master(109), final versions(108) and sketch generated code(109).

If the sketch generator use Master/beta code(109), then it cant be used to program latest "stable" version(108)? or am I wrong?

Perhaps the sketch generator page could have an option; use latest stable version or beta?

 

[alphaomega]

@Hans-Einar: Yes, the webpage generates latest sketches (same as master).
If you'd want to generate 1.08 you'd need to use the webpage supplied with that release.
There are changes in eeprom layout, so supporting older versions would be a mess.

Does anyone have any info on how to mod the freezer wiring to have a working light switch? It only works when the STC1000 is in cooling mode.

I'm also installing an air recirculation system from THIS THREAD and was wondering if it's possible to wire the switch so that when the lid is closed the light is off and the fan is on, and when the lid is open the light is on and the fan is off?

Many thanks,
KindofBlues71

Can you post a clear pic of the freezer's wiring diagram? Doing what you want will require modifying the internal wiring of the freezer.

Here's the wiring diagram for my freezer. It's an old Kenmore that Sears can't tell me anything about because it's no longer in their database:

Something like this should do what you want.

Thanks doug293cz, I appreciate it!

I should have been more specific, but I'd like to have the switch controlling the light and fan on its own separate circuit and spliced to a plug, but I think your diagram will get me there!

Hey mats,
like the new format with the SP being first on the list. Just wondering if something was missed in the change. If I program using "f" some of the settings are off,most notably, the Alarm, SP, and I believe both HY settings. I can't remember if any others were wrong. As soon as it finished programming, the alarm started screaming because it was set to 70.0 (my SP) and I think my SP was 0.5 (my Hy setting). I believe the HY and HY2 were both set to 0.0. Not an issue if I program using "g", but I just figured i'd let you know.

Thanks again for all you've done!

@RocketBrewer: Thanks a lot for reporting! I'll check it out as soon as I can and see if I can find the issue and fix it. Did you use the profile editor / sketch generator web page or just downloaded the ino file from github?
If from the webpage, then it might be some browser issue or just something I missed. It is a little tricky getting that right...

 

[RocketBrewer]

I used the web page. Here are the parameters I set.

 

[alphaomega]

Ok, so now I think I have it fixed
@RocketBrewer: You didn't spot the mistake? Well, I didn't either obviously....
I forgot to move SP first in the list of Set parameters in the web page. *doh*
I really thought I did check (and double check) that the parameters were generated correctly by the web page, as I did change a lot of stuff there. But I must have missed that somehow anyway.
Please let me know if any other issues are found!
Thanks again RocketBrewer for spotting this!

Cheers!

 

[alphaomega]

I have done some refactoring of the web page. I think I've fixed some minor issues.
But most of all, I have added a feature to save/restore the settings to/from a cookie.
Granted, this might not be the most flexible solution, but at least it is something.
Again, let me know if you find any issues.

Hmm. Maybe it is only my computer but Chrome and Edge give no reaction when select any shetch version..

 

[jleiii]

Same thing for me with Chrome.

 

[balrog]

Ditto Chrome and IE

 

[Dunkderby]

same for me with Chrome

 

[alphaomega]

Whoopsie
Thanks a lot for noticing! Funny thing is it worked in FF... Well, my javascript skills are not that great. Special thanks to @HansEinar as you were first on that.

@Balrog: IE? You expect anything to work in IE?

It should be fixed now. Sorry, for that. Please, continue to report if anything else pops up.
As a side note, testing in chrome, I found out that chrome does not allow cookies from locally hosted pages. Works fine from the web though. I'm sure google has some good reason for that in their 'infinite' wisdom, but it sucks...

Thanks again y'all

Cheers!

For those of you running the dual probe set-up, what is the general consensus for the hysteresis settings? I am going to run a walk-in cooler using an AC with one probe exposed to air and the other in a probe into a mason jar filled with water.

@Balrog: IE? You expect anything to work in IE?

I work in IT; I have learned to at least try different browsers before crying out.

 

[alphaomega]

@balrog: I'm in IT as well. The benefit of open source projects is that I can do what I enjoy instead of testing
I mean, I try to get it right, but I'd rather not do a whole bunch of regression testing.

@ben58: Sorry, I have no idea. And it will likely be dependent on your particular setup, so I'm not sure anyone else can give you a definitive answer either.

 

[RocketBrewer]

Flashed a couple new controllers today using the web page download and worked great this time. Being able to restore from a cookie is AWESOME! Can't thank you enough for all your hard work Mats!

 

[demig]

Long time lurker but just registered and just done this to my STC, fabulous software extremely impressed. I have a question which has probably been answered somewhere in this thread but there is so much I probably missed it!

To flash the unit it has be be disconnected from the power but I'm wondering if the arduino can be connected when the mains power is on? What I want to do is build my arduino nano into my case with controller etc leaving usb port accessible so I can program profiles from the web editor when the power is off. This would mean the arduino needs to be hooked up all the time, is this possible?

Alternatively would it be a problem to leave it hooked up but with a switch in the 5v line so this link is off when the mains power is on but could be switched on when mains is off and computer is connected for programming?

Thanks for the hard work on this, really appreciated.

Hi and thanks!
There should be no problem leaving the Arduino connected.
I would suggest using a diode on the 5v-Vdd, to avoid the arduino being powered from the STC. But, it should be fine without it as well.
If you don't add the diode, then you should avoid plugging in the usb while mains powered.

Thanks, I should have thought of that, nice simple solution and they are the best

Has anyone tried this with an ITC-1000? I know they already show Fahrenheit but I am curious to know if it is possible to gain the ability to ferment for a set number of days at a specific temperature then program the unit to change temperatures in case of being unable to manually change temperatures.

Thanks. I tried a search in the forum but couldn't find anything close to what I was looking for.

Ok guys I'm about to pull my hair out with this thing. Long story short, I built a herms system, and I'm using the stc-1000 to show me my mash temp. I only want to use the 1000 for just the twmp, it does not need to control everything, I've tried different probes but all I keep getting is EE. Any ideas ? Do I have to use a ssr to power this thing? Sorry if this is on the wrong post but I couldn't find anything else on this. Thanks in advanced
