Hi Amigos, look here www.ebay.de/itm/Nivona-Display-Ersatzteile-Kaffeevollautomat/254181615754?hash=item3b2e67a88a:g:Bu0AAOSwbTJckR-5 I am also curious if your experiment has been successful. That would be a great break !! Added after 1 [minutes]: Palal, which check valve?

Thanks. From him I bought 2 pieces at the auction last time and are already waiting with friends in Germany. Unfortunately, friends are currently in Poland and are going to be in two weeks. Only then will they send it to me

And for me from today in Nivona 850 the display shines again, only that in yellow ... The cost of repair (parts) is 170 PLN

I am looking for help in the form of a person who will repair such a display, please contact me 693140790

How long did you wait for the implementation?

I ordered, delivery a few days from Slovakia ... and again I'm enjoying the "operation" of the coffee machine after the exchange. This time in yellow
My friend who has the skill and access to the equipment (especially the microscope) has turned over - I do not recommend to anyone who is not fluent in these blocks.

Buddy, is there any chance for you to help me repair the display, how would I send it to you, of course for an additional fee?

I have two displays of stimulants for sale. For soldering and checking. greetings

But the displays themselves? You need the whole module like this https://www.ebay.de/itm/Nivona-Display-Ersatz...tem3b2e67a88a:g:Bu0AAwbTJckR-5&frcectupt=true The same un-soldered oled is in the dustbin

Hello, Does anyone have to sell the ssd1303 display? Or is there still a chance to buy them? In return, I can help someone in exchange. I have equipment, hot air soldering machines and quite skills.

Those with the SSD1309 controller also work: Unfortunately, the controller is placed on the tape vice versa and the image is mirrored horizontally. However, I managed to get around this problem: Unfortunately, it is not so easy: If I finish it, I will post the solution on the forum.

Can you specify which pins you replaced?

At the top of the display output from the coffee maker - view on the plate pins, not the LCD tape itself. At the bottom, the display on SSD1309, here for the change, 31pin pins. There is an I2C / SPI version on the Allegro and, unfortunately, the inactive D0-D7 pins have been connected to ground and so maliciously that there is mass from the front and back (it is impossible to cut the ground path without soldering the tape) and a short between the pins. I soldered with a tape to the tape points, but you could do a dedicated tile. The signs match. BS1 and BS2 connect to + which gives the bus 8bit mode as 8051, which is separately RD and WR. This combination will give us a picture, but a mirror - you can get used to it.

Thank you very much. In two days the display will come to me, spd0301 with 24 pins, I will try to use your diagram. If it fails, I will order ssd 1305 or 1309, because the pins have the same.

The system for removing the inverted image does not require FPGA - three CMOS circuits were enough.

How do you find the moment, will you place the exact diagram with these cmos layouts?

I designed the plate and we'll see how it works.

Cool. Eventually someone took care of this problem and the topic started. Congratulations on the solution. We are waiting for the final description. "redzid", maybe you can check faster, what I wanted to check with spd0301. For me it has the same pins as ssd1303 except for the extra BS0, except that it is arranged differently. The connection of BS2 and BS1 to +, BS0 to - should give it the 8bit bus in accordance with table 6.2 https://www.usmicroproducts.com/sites/default/files/SPD0301_1.0.pdf. I think that spd0301 would not require additional layouts only for the board / adapter /. I already have the spd0301 display, I ordered this plate https://www.aliexpress.com/item/FPC-FFC-flat-...rectly-inserted-DIY-0-5-mm-spacing-connector- 6P / 32827105259.html? Spm = a2g0s.9042311.0.0.49914c4dhj9wJj and I am just waiting for the entire display module to check it out. It's nice that the topic has moved.

Prototype etched plates.

I'm curious to see how the spd0301 display will behave. I ordered such an adapter on allegro, except that the connector and PCB is separately and need to be soldered. I think that tomorrow should come to me, I will be testing

Nice, because the order of the tracks is from the same page in both displays, so on a possible tile there would be only 2 intersections of paths. On the schematic it would look something like in the screenshot below. If you find an error in this drawing, let me know. Always two heads, it's not one Connectors in the example diagram.

It's ok. According to the catalog cards, the order is correct.

I made a mistake on the board, but Kynarek solved the problem. This is how the board mounted in the housing looks like: And the end result:

Satanistik, could you put a graphic to print the tile with the description of individual parts?

Today I connected the spd 0301 display via the connector / adapter according to the amigos drawing. Indeed, the display works, but unfortunately the image is a mirror image, as in ssd1305 ssd1309, etc. Satanistick solved the problem, but apart from the pictures, he did not include the diagram, it is a pity. Maybe he'll call you again.

Well, it's not like a mirror image. Also there is a break like in 1309? I've read that there are displays that can be forced to invert the image. I do not know much English, but I'd like to delve into the specification https://www.usmicroproducts.com/sites/default/files/SPD0301_1.0.pdf. Especially in Chapter 7. The display of the image may depend on the condition on the specific display pin. There is someone wise who would study it? I see that the speech in it is also about mapping 132 columns, but I do not know what to associate Next week I should already have my displays, I will pokombinuję

Yes, there is also a break on the right.

The PCB must be improved so that you can solder the display itself without wires.

Thanks for the scheme, but I find it difficult to get to him I would need a more pictorial connection scheme.

If some of the forum members do tiles, you could order more together and the price can be good.

In the event of it, I would be willing to buy a tile.

Is the missing line caused by an error in handling, is this how it should be?

Old LCDs were reportedly working in 132x64, and those replacing 128x64. Here is the problem with the lack of columns.

And you were looking, maybe, in the case of sdp0301 is it possible to force him to image 132x64? It seems that thanks to your modification it should also reverse the image in the same way as on ssd1309. According to the specifications, sdp 132x64 is called to give the pin high on LS, but this pin probably is not derived If your modification on sdp0301 works, I will be able to check it out within 1.5 weeks. Then the problem of the display replacement and the missing columns would be completely solved. In the case of sdp0301, there is also a better solution, because at least you do not need to solder the display, but only connect to the FFC24 connector. The small connector therefore has more space on the circuit board for the arrangement of the circuits. The board would only need to somehow connect with the original connector on the module's board. As for the tile, you would need to talk to someone who does it every day. I tried to play on the Eagle, but you have to have an idea and skill. In any case, if someone did, I would also like to take tests.

If you confirm that sdp0301 will work, I can try to make a plate.
