It says "heater short circuit" at the beginning of heating. After while it's gone and temperature ramps up without any problem.
Handle is JBC T245 supplied from 150W 24V Indel trafo.

What handle and what power supply are you using? Does it show "heater short circuit", or "sensor short circuit", and for how much time does it show it?

Do you have earth connection or not?[/quote]
Still have some Unisolder PCBs available... 12euro per set.

I figured out for example the IRF 3205S:

Too low voltage. You need at least 75V part, if you are using 24V transfomer for power supply, which, as I stated before, is the best possible power source for this controller.

and the IRF1404S:

Same here.

MOUSER has plenty of IPD053N08 in stock. Farnell has it too.

The important features are 75V Vds minimum and around 0.01ohm resistance, or lower. Higher resistance alternatives such as IRF2807S may also work, but I cannot tell how warm will they get.[/quote]

I used IPD068N10N3.

Sparybg, Iwanushka thanks for help, now i get 12V for Oled VCC.
Anyway program PIC32 firmware - standalone and turning on the station nothing on the screen.
When I programs PIC32 with bootloader firmware file then power on in Oled appears cubes (see picture).
This means that my screen work and the fault lies somewhere else.
What could be the problem.

Maybe you are using wrong firmware.

Program it with "softwarefrontUS_Firmware.XdistPIC32_StandaloneproductionUS_Firmware.X.production.hex" as provided in the "rar". Don't recompile it.

The cubes shows that you are in "bootloader" mode, so it is normal. It stays there if no firmware is uploaded with bootloader.

...and, look at datasheet of your display if it wants 9 ot 12V and change the feedback resistors if needed. My blue display wants 9V and my Yellow display wants 12V.

Hello Sparky,

thank you for your quick answer. Please help me again with the reason for this high voltage. Behind the bridge rectifier I  would expect a voltage about 37 volts if the transformer - and sure I will take one - has 26 volts with no load.  Or are there inductance spike when switching off?
Where is the mistake I make?

Where exactly is "behind the bridge"? Pay attention - there is not a filter capacitor directly behind the bridge, so the voltage there should be half sinusoide with 5V plateau.

Hi,

could you post here or pm me with a link to the oled you bought?

This one is out of stock[/quote]

They were not in stock when I bought them. We ordered around 70pcs, if I remember well and they arrived a month or so after we paid for them.

Any 128x64 OLED with SSD1306 will work. Ebay is another source, but mostly they are made by different manufacturers and with considerably shorter lifespan.

Sparkybg,

I've bought this one http://www.ebay.com/itm/0-96-I2C-IIC-SP ... Swv0tVeD0N

It comes with I2C, I hope they did not butcher the controller and it has SPI interface, so it would be handy to have ebay link with known to work OLED just in case :)

Note: assembled OLEDs on ebay are 1/2 price of OLED screen itself...

I'm using the same approach. Hope mine will work. The bad thing is the quality and absence of any documentation to display itself.
BTW what are the symptoms of low VCC to the display - is it dim, low contrast or information isn't visible at all?

I used OLED from aliexpress.
Works just fine. Good brightness and contrast. 4 USD.
Just too small.
2 inch would be nicer.
Still have some Unisolder PCBs available... 12euro per set.

Later on I'm planning to hook up 4.3" LCD to this thing :)

Sure. Here it is:
http://www.ebay.com/itm/0-96-128x64-OLE ... 0751769678

and another one:
http://www.ebay.com/itm/0-96-inch-30-Pi ... xyE-dRyW3N

Aliexpress:
http://www.aliexpress.com/item/0-96-inc ... .81.dZyiAK

Most of these are made by Univision, and the model is UG-2864HSWEG01 - datasheet is available - just search for it in google.
For example: https://cdn-shop.adafruit.com/datasheet ... SWEG01.pdf

I don't remember the seller I bought my first one from. But it was eBay, and it was white, and it required 9V instead of 12. And it was sold as a pair, for around USD10.

There are 2 inch displays with SSD1306, but you will have to make another PCB for it - the pinout spacing is different.
