TC4 with aArtisanQ_PID

I uploaded a public beta of Artisan v1.2 on its GitHub home.

Thanks for your help Marko!

KKTO Roaster.
I uploaded a video as it works practically and from start to finish fully automatic (80/70mm fluid bed roaster 1.7kW, 500W motor).
I changed the thermocouple and set the position in the roasting chamber so that the degree of roast corresponds exactly to a bigger (120/110mm) roaster in the same profile.
The small roaster can be used as a sample roaster.

I'm inattentive, currently I use other button settings:

How do you get that RoR guidance curve on screen, is it added in post processing, or an Artisan feature ?

This is real time RoR plot, I have this checked, is not what I meant, but the curve already on screen before the roasting started.
You probably think of the DeltaBT in Profile Background.
Profile were created in Artisan Designer.
So I added fan control to my TC4 with my Quest, works great! Does anyone know how to get an LCD that would tell me my fan output? I was looking for something that would give me the duty like the heater (OT1), but I can't find anything...I need an OT2 readout.
The TC4 sketch supports a connected LCD (16x2 or 20x4) using the LCDapter board that Jim sells.

I think it may also support a standard parallel interface but I've never tried.

I want to try using one of the cheap i2C LCDs available on ebay instead of the LCDapter but haven't tried this yet either. It would required a few tweaks to the sketch.

Alternatively, you could connect the TC4 to a computer and monitor/log the outputs using Artisan.

Or add a bluetooth module and monitor outputs using my android app.
@greencardigan, I guess I should have been more clear, I want to be able to log the fan output using artisan. When I said LCD, I was referring to the mini LCD's within artisan.

I just can't seem to figure out where the OT2 data feed is within artisan. Any ideas?
Have a look at my videos here.

Similar roasting, only the fan slider moves, is here:

If there is someone who has tried TC4 shield + Arduino Mega, write here.
I'm interested in any result. Also, that something did not work.
Brad, those ebay I2C won't work, wrong chipset, I've probably got about a half dozen I could send you, some still wrapped. some off the backs of displays I had too take off. Now, if you want to wright new code, You can probably make it work. It takes a lot more than changing the address.

Now, what I will do, I will send you a Digole TFT if you will send me a copy of the sketch you have to use to get it working. I've got q 2.2 I2C one I ordered wrong for a battery tab spot welder and I cant even figure out how to change the address in. I've never learned enough Arduino to program. 2.2 is pretty small, a lot smaller than a UNO board. so I'm sure you would want something larger than that. If interested, send me a PM.
The reason I suggested the Digole, they are well supported with documentation and user forum for someone that understands this stuff a lot better than me.

Yes, I understand I would have to use a different LCD library to get the ebay I2C LCD working. With the LCDapters being hard to obtain, an easy to source alternative would be good I think.

Getting the TFT to work would also required a different library but would probably be more complicated. I'd also be worried about the memory available. The aArtisanQ_PID sketch already has very low memory free.
Shoot, I thought I might slip one over on you.
To keep from getting this tread any more off subject, I sent you a PM.
Hi All,

I hope to release a small update to aArtisanQ_PID soon which adds a few features. I've attached a beta version of version 6.4 if anyone wants to test.

- Support for LCD screens other than the LCDApter. Given that LCDapters are a bit hard to source, I thought it would be worthwhile adding support for the cheap I2C LCDs available online on eBay etc. Thanks BenKeith for sending me the LCD for testing.

- Support for two buttons directly connected to the Arduino input pins (ability to reset timer and toggle PID). This may be useful if an LCDapter is not being used (the LCDapter allowed buttons to be connected to the LCDapter board).

Let me know if you have any issues.

While working on my TC4 roaster application, I came across an issue between 6.3 and 6.4.
I'm working with a TC4 board with both potis connected. With 6.3 the values from heater and fan are been transferred to artisan correctly.
With 6.4 , heater works fine, but fan transfers the values multiplied by 10, meaning if I have e.g. 55 in the TC4, I have 550 in Artisan.
By the way, how can I get the sliders in Artisan stains in sync. with TC4?
When I turning a pot from the TC4, the sliders in Artisan stay where they are ...

Thanks in advance,
Check Alarms.
Not exactly what you want, i.e. not continuous following, just some predefined levels, but no idea if something closer to your intended purpose...
