'Real' CRC is too costly for the STC, but there already is a checksum implemented in the protocol. That is why you even get communication errors, otherwise you wouldn't even know something went wrong. The 'right' thing to do, is what you were already hinting at. Wrap the read in a loop (i.e...

I've been making pretty good progress with the ESP stuff. Greatly improved on the HEX flashing. Now you can load a page (hosted on the ESP) and stream the HEX file over a websocket to the ESP, that flashes the STC on the fly. The profiles should be editable (using a modified version of the...

Quite the rebuttal. Well, I'm sorry if I was too harsh, but it is not the first time that you just ignore the point I'm making and just quote the one part that you disagree with (out of context).

Oh man, not again... You can't draw everything in black and white. Just because it is cheap it does not need to be bad and even more true, something need not be good because it is expensive. It is about knowing what you need and what it costs. I just said that it is not good for everything, but...

Yes it is. When buying off eBay, aliexpress, bangood or whatever, you need to know that you don't pay a fraction of what a brand product cost and expect same quality. I don't even think they are (intentionally) lying when it is branded 25A. It probably started out as a design with a beefier...

...you just need to ~halve the specs :) Stumbled over this video on the tubes, and thought it was interesting. Nice to know the Foteks are semi-decently designed, just not quite up to specs. All the more reason to get the 40A versions and hope it really has a beefier TRIAC (and not...

Ok, so I've got a repository up on github. I've still not cleaned up the code and it lacks documentation, but at least the code is there. It is just proof of concept stuff, but still pretty cool that it works. Now, the real work begins... *sigh*

You are welcome to try it out if you want to, but just know I have pretty much abandoned the project (in favor of OVBSC, which is more targeted and simpler). It's been a while, but I think I got the PID sort of working, but it is not without limitations. There is no floating point, so I think...

Very cool :) I don't know if you have followed this thread, but I actually played around with the ESP myself. I used a framework called Sming, which has Arduino support + a lot of other cool things. But I never got it working reliably. So, I kind of lost faith in it for a while. Turns out...

Sure, it is kind of the point with the com firmware. Just a tip though, don't send commands too quickly (that is, use a delay beween each command sent of at least 10ms). Due to limitations with the protocol, communication state resets after 10ms, so if there is a cimmunication error, it allows...

@ldzielak: Hopefully I have fixed the com.ino sketch now. At one point I refactored the menu system in the STC-1000+ code and forgot to change com.ino. Unfortunately, with my current setup, I cannot test com stuff, so I couldn't verify that the change I made is correct, but it'll hardly make it...

Measure the 5v line when powered from mains. Sounds like the voltage regulator, it's a TO-92 package component between two capacitors and just to the side of the buzzer. Doesn't matter, now I know :) Thanks for that I'll look into it when I get a chance. It does sound like a register mapping...

Nice! Can't wait :) I love git, I just can't wrap my head around it :) I grew up with CVS and SVN, and as much as they sucked, at least I understood them :)

I hear ya! I have done some C optimization, but I haven't analyzed the generated code, but I think you are totally right. I've just tweaked until what I needed to fit, would fit :) That should actually generate no code at all :) That should just be the top 8 bits (i.e. the high register) of...

Hi Sean! I'm glad you registered to HBT! I like to keep discussion of STC-1000+ here and not on github and I really welcome your input! I agree that SDCC might not be the best compiler for the target (and I think the PIC targets are not their prime concern), but it is open and was a deciding...

Steam will escape with the lid on as well, and with it DMS.

You might be interested in this thread I started on a swedish forum. I guess the pictures are pretty self explanatory. Just note I made an error in the first post, you need a 4-pin JST XH extension cable.

Well, it was a short, so you weren't wrong :) Good to hear @lewisash .

@lewisash: Glad you worked it out. I was late to the discussion, but my suggestion would have been to check your soldering, as is seemed like a short between ICSPDAT and the relay control line. But, if the relay is still in there, then I agree with you, that is most likely the issue. You can't...

Sorry for the late reply. First off, I still don't agree with different hysteresis for heating and cooling, but if that is something you want AND you fixed it yourself, then kudos! The child lock feature is a pretty good idea though. I've had a quick look at the PP_005 branch, and I think...
