Non-standard firmware for a bread machine. What features are missing?

Good day!

An interesting question. Is there enough in the standard programs for Panasonic bread makers?
Does it make sense to do advanced programming?

For example, I sometimes don't have enough time to manually set the timer for raising the dough, I either have to turn off the oven to let the dough rise, or use separate kneading and baking programs. In both cases, the dough rises without heating.

I have little experience in baking, but I have enough experience in electronics to carry out such a modernization, so it would be interesting to jointly compile a list of programs of interest, if, of course, someone needs it ..

Alex_VI Everything about technical research is always interesting.

Is there enough in the standard programs for Panasonic bread makers?

I clearly lack the ability to run the heated proofer from 30 minutes to 5 hours as a separate program, with the option to turn on / off kneading or deboning.

For example, I sometimes miss setting a timer manually for a test

I completely agree,
1. We really need a program to set the long proofing of the dough.
2. You need a sweet bread program; on a regular program, butter bread, as a rule, is too fried.
PS. Let's hope that these wishes will reach the addressee (Panasonic campaign).

and yet, apparently, it is not really necessary .. three out of 175 only checked in ..

The fact is that many simply could not see this topic.
I really like this forum and its inhabitants, you will learn a lot of useful and useful things. However, he is very multifaceted and deals with many topics.
But at some point, his advantages turn into his own shortcomings, since it is not always possible to track everything that comes new. But this is purely my IMHO.
Maybe the "button" tape version of the forum would help?
But this is another topic for the organizers of the forum. Anyway, I am very happy that I became its inhabitant.
In general, I treat Panas 257 without much reverence, but it's not a bad CP, but I will not sing praises to her, as is done everywhere, there are also a lot of flaws.
At least above the unpretentious Hitachi released more than 20 years ago (that is how many years it worked without a single breakdown), I will not put Panas.

Dear ones, there has already been at least one topic about what is missing in bread makers.

I confirm! My unpretentious paw Hitachi is 15 years old, and everything works, and often, and without breakdowns!

I am among those who did not check in, according to your words ... I will explain why: the message does not understand your powers, opportunities and whom you represent
And also, in my opinion, Panasonic HPs occupy their own niche, clear and definite, and you want, if I understood correctly, to take you to another area. How much to expand the programs? Here are how many questions I have before proposing

I don't represent anyone, I'm on my own
I just have this stove.
According to the programs, if something is done, it will look something like this. Since the regular processor is too highly specialized, the search and purchase of debugging tools and documentation for it will be released in a rather long time and money, which is inappropriate.
The easiest way is to take another microprocessor and completely rewrite all the programs. Accordingly, the completion of the stove will be reduced to re-soldering the microcontroller. It makes no sense to do such work for one of my stoves, but if there is a prospect of selling this solution to a sufficiently large number of people, then this work can be implemented.

There is another option, a complete rework of the printed circuit board (there is nothing complicated in it), with the installation of a different display (since the native one cannot be found and its functionality will not be enough for advanced programs). This will allow anyone to replace the board in their oven (reconnecting two connectors is not difficult)

Well, that's what it was required to prove. Many topics, you just do not have time to browse.
Probably it makes sense to add this topic to the previously existing one.
What do you think gentlemen moderators?
Although the topic, I consider necessary, and sooner or later it will come in handy in the next model (258,260, etc.), perhaps the manufacturer will take into account our wishes.

Thanks for the answer and clarification.
Now everything has become clear and you can have conversations!
When choosing HP, I took into account all its features, and during operation, I learned to "interfere" with the programs to a minimum. At the present time, everything suits me in HP. If there is a need for something that is not in this HP, then I will choose another

The easiest way is to take another microprocessor and completely rewrite all the programs. Accordingly, the completion of the stove will be reduced to re-soldering the microcontroller.

Greetings colleague! I am for it. I do not like that the stove is "on its own", well, at least a couple more indicators were added - it's worth a penny! And then you don't understand what she's doing at the moment, maybe she fell asleep ... I don't like the trend of recent years, when equipment is released for users who only need to press buttons ... You give personalized firmware for branded recipes! I would also build a radio module, a LAN interface, or an IR remote control as a last resort))) I would add sensors (humidity, temperature, pH of the test) And what "Trojan" firmware can be written))))) and sent to enemies
Who has a stove that is no longer under warranty, maybe it's worth a try? If anything, I will sacrifice my electric stove - I really do not like how the thermostat works in it, I should "patch" the oven ...

[Oca]

Oca Yeah, especially if they have a controller of the type S3CC921 This is good if the memory 24С04 can be easily opened by PoniProg, but if not It will remain a dream. Engineers of the company "do not eat bread in vain" since 1987 have already worked out the program IMHO

[sazalexter]

sazalexter, I propose to see which leg of the controller is connected to what and at what point in time what is transmitting. View signals from the temperature sensor ...I think that this will be enough to write a code that repeats the results of the operation of the algorithm of the Panasonic processor. I don’t know the mentioned controllers, but I used PonyProg for flashing Atmel microcircuits.
Thank you for the link to the HP documentation, I read it for general development

....
An interesting question. Is there enough in the standard programs for Panasonic bread makers?

....

Improving Panasonic is a good idea, but there is only a fly in the ointment.
It's very simple, just calculate how much a new controller will cost for 500 - 1000 ovens?
One graphic display (cost) is already disheartening, and the dreams of some users here about a remote control and other delights, the cost of happiness is also raised to a rather cheerful height.
Ask how much the user does not mind spending rubles on this and you can safely go to drink tea, forgetting about this idea!
And stoves have already appeared with all the tasks solved in terms of programs.
Here Bork, for example, pasted his label on one such stove.

Today they finally sent me an order: a thermocouple that can withstand heating up to 300 grams. Celsius. Tomorrow I'll blow off the dust from the box where all the microelectronics are stored and start writing the program ... The 1985 electric stove was chosen for the role of the victim, for a start I will teach it to time the time, withstand the temperature and inform about the readiness of the food.

I would vote with both hands for tuning Panasonic in the topic of adaptation to leavened bread (kneading-standing-baking) with the possibility of manually setting time parameters. The type of operational manual programming at the time of placing the ingredients ...

with two hands would vote for tuning Panasonic in the topic of adaptation to sourdough bread

Yes! The very thing! I stopped baking with sourdoughs, because there is not enough program time for raising the dough, and I cannot keep track of it manually. Although with them the bread turned out to be more flavorful

It would be great if there was a separate function for proving dough with a heated timer.

Cool ... but all this is from the category of fantasies on the topic "Now, if only ..."

These are not fantasies, but quite real proposals. Question to the moderators: Didn't Alex_VI appear again? I will also familiarize myself with the topic of improving the HP R-2500. Maybe someone knows how to increase the volume of the signal. Display backlight is needed. And this is offhand. And if you think about it, you can offer more.

And what's real here? To create for Panas a formula for an ideal bread machine for the post-Soviet market? Or would someone offer a new $ 100 management fee for some money and there would be a line up? Yes, I would be the first to sign up, but, as practice shows, everything ends as it began ... If only a cunning specialist from some manufacturer does not understand that there is still a niche in the market for new products ... and for our HP this is, unfortunately, it will not have any relationship.
And you don't need to add a couple of LEDs under the scoreboard and replace the buzzer (or screw it on) you don't need a lot of mind, half an hour of free time and understanding about the loss of warranty claims ...

And add a couple of LEDs under the scoreboard and replace the buzzer (or screw it on) ...

And this is a thought! Give me polyphony! There are so many devices in the kitchen and without HP, and everyone squeaks in the same way until you figure out which one of them is giving ...

Yes, I basically mean the same! Now there are two opinions: yours and mine. I respect yours, and you do not really roll on mine. I repeat: These are quite real proposals. And there is plenty to choose from. Read here:
https://Mcooker-enn.tomathouse.com/in...ion=com_smf&topic=2025.20
By the way, there is a justification for prices. And we will end the argument with a quote from the same place: "... It is a well-known fact - in what year Bill Gates beat himself in the chest with a bast shoe with words like" there will never be programs that need more than 640 kb of RAM "I apologize, but in your computer how much? ... "

"I'm sorry, but how much is in your computer? ..."

I have a Celeron (R) CPU 1.7GHz, 1.5 GB of RAM (they recently gave me a gig bar, because at 600MB Contra is terribly slow) And in an 8-bit AVR that I am currently programming, a whole kilobyte of memory I will change the 32-bit ARM controller to which thread, if I find where to buy ... I'll adapt the old AVR later ... sorry, the stove is still under warranty

As the classics used to say (in a free interpretation), that practice is the criterion of truth.
I'm waiting for suggestions on replacing the standard control unit with a tuned one, operationally adjustable.

The minimum task is to draw a principal and read the contents of the controller. There is neither one nor the other in nature, (there is only a service manual.)

My proposal is simple: 1) make several modes (Simple, Rye, Sourdough bread, Dough), 2) allow the user to configure each mode and store its settings in non-volatile memory. An example of Sourdough Bread: knead - 15 minutes, rise - 30 minutes, knead - 5 minutes, rise 4 hours, bake - 50 minutes, signal at the end - Loud (from several possible levels), keep the bread warm - no. Let everyone adjust HP to suit their taste and the amount of dough to be put

The controller in SD255 is manufactured by Panasonic MN15G1601JS1, which is typical for the products of the datasheet company 🔗
all logic is collected in it

... And then he took it, put the song "Bread - All Heads" instead of a signal and immediately it would be more fun

I would also play this song: "... There it smells like a hot bread in the house, and a river runs somewhere under the mountain .."
I subscribe to the "simple sentences" of Wasp.

[Boriks]

And you don't need to add a couple of LEDs under the scoreboard and replace the buzzer (or screw on the music), you don't need a lot of mind, half an hour of free time and understanding about the loss of warranty claims ...

Boriks , so teach. After all, here we are talking not just about the MIND, but about special professional knowledge, which, as I understand it, you have in bulk. The warranty will end, and with bated breath and eagerness I will disclose your developments and recommendations for sticking LEDs under the board and screwing on a musical instrument. And I am sure that I am not the only one who will remember you with a kind word. So we are waiting, sir! I mean myself and Osu. Who else is joining us in anticipation?

We are now waiting for an answer, about the MN15G1601JS1 controller who can not read and disassemble it personally

[Sazalexter]

Sazalexter, in order to disassemble the firmware, you need to have at least some idea of ​​the microprocessor command system or its architecture.I cannot, there is not enough information ...

I propose to see which leg of the controller is connected to what and at what point in time what is transmitting. View signals from the thermal sensor ... I think that this will be enough to write a code that repeats the results of the operation of the algorithm of the Panasonic processor

That is, our primary goal is not to pick out the stove to the bottom. "Why reinvent the wheel when our job is to ride"
In general, I dream of making myself not a kitchen, but a spaceship. Only the price will be comparable.

[Oca]

Oca So I mean that this idea can be safely pushed. The firmware for the processor cannot be found, there is no logic analyzer, and it will not help much from here. The chip developed by Panasonic, protected by patents, what else would they say that this is an infringement of intellectual property

Initially, it was, as I understood, not about "improving" the native control board, because it is foolish to think that there is still a reserve, but about an alternative, made for our consumer, who is not satisfied with bread with fast yeast. This is a fantastic task in terms of the final result, because the costly part can be economically calculated at least somehow, but the return is very illusory. There are no patrons.Well, we sat and talked, maybe some of the representatives of the "well-fed" manufacturer (read the eastern neighbor), having calculated a promising market for a "thinking" user of HP, will release it in a few years (because old models are not particularly stale on the shelves).
IMHO, of course ...
p.s. Although, for an enthusiastic person who wants to occupy an empty niche in tuning and at the same time earn money there is still a chance to put hands / head

... which Alex_VI suggested at the very beginning, opening this topic. That's how I understood it.

The fact of the matter is that ordinary users are overwhelmed by the existing set of functions and they combine them to achieve the desired result. The "advanced" bread maker is mostly needed by people obsessed with technology and computer technology. Although, as I recently read about Brand multicooker, this company has just developed equipment based on the wishes and whims of customers, for which they have great respect. It is difficult to say about the prospects for the commercialization of the developed new HP board, for example, for the modernization of old models ... The implementation path is very thorny. But at all sorts of radio forums there are such proposals: "I solder the programmer ..." or "... the hand itself has curves, who can collect and send by mail for a fee?" So you can try to sell on forums and through free classifieds sites (for example, ). I would have bought it for a thousand, so as not to waste time More expensive - no, I will collect it myself)))

perhaps "a thousand" will be within the cost price. And for remote ordering you need to give those. a task in which to designate the incoming / outgoing conditions, but they are not defined, because there is no description of the characteristics of sensors, heating elements, control panel. And no one will free the "upgrade" seller from the "support", but who will hang this Domokles sword on himself?

[boriks]

I no longer get bored with the "music", which "a lot of mind is not necessary" to shove, but at least teach me to change the squeaker, boriks... In mine this squeaker beeps quieter than in a wristwatch! Tolya is in the microwave!

I do not climb into HP for Principled reasons. Over time, it was just a disaster. And if you "start the combine", then certainly not because of such trifles. Time, everything depends on his lack of grip ... and if the standard one is replaced with a signaling / buzzer by choosing the parameters, then the neighbors will be glad ...

The service manual is on the forum, it has a disassembly diagram, you get a control board with an indicator and a processor, a "piezic" is soldered on it, replacing it is a very simple matter

Thank you sazalexter !!!

Dear specialists! Here is a piezik of 20 rubles 🔗] ,
here is the program for the melody: 🔗] .
I know what to do with the piezic. And you can somehow add this melody?

except perhaps to reel in next ... but seriously, all the "brains" of HP are in "mikruh" ... just there are "buzzers" with "sewn" melodies, if in simple language ...

[Wit]

Wit
You buy a musical postcard and attach it to the place of the piezik, how? It is necessary to think about it. As an option, look for an amateur radio circuit for a programmable electronic call, 10 years ago I saw something in the Radio magazine, just don't remember, don't try ...

This is approximately what Lan thought, I can do without a melody, but only a squeak. 78dB, I think that's enough!

That is, only bread makers can be given.
