Update my old TC4 with latest software version
allenb
I'm using my original TC4 shield with Arduino Uno with circa 2010 software and notice that the rate of rise numbers drift up and down outside of the area it should be reading. Comparing the rate of rise response of my newer TC4C, the newer version tracks very smoothly.

I want to reload the old TC4 and Arduino with the latest software offerings to see if this will help its rate of rise readout stability. I'm only using it for rate of rise readout.

In order to reload the old TC4, is this thread the place I need to go to pull this off?

The RoastLogger site has links to the latest TC4/Arduino sketches. Use these links instead of what is listed in my instructions.

http://roastlogge...nload.html

My Roastlogger instructions are out of date (Links to old versions of software and drivers)but are still usable and referenced on the RoastLogger site.

You will also need to download and install the latest Arduino IDE software:

Let me know if I can help.

Is anyone still supporting RoastLogger ? From the site seems not... :(

Greenbean posted (8/17) that he will not be able to provide online or email support for the rest of this year for personal reasons. The Roastlogger site is still active and should provide enough information to resolve most issues.

I'm not sure that changing to a newer sketch will make the ROR more accurate. I don't recall any changes to the ROR calcs. Maybe your newer TC4 has a higher filtering level set for the ROR calculations? You can adjust the filtering levels in the user.h file before you load the sketch onto the Arduino.

That makes sense to me. I remember reading quite a while back where Jim was trying to change the time base for how often the TC4 would update or something to that effect to try and smooth out random fluctuations. Do you know what actual variables I would need to update in order to utilize the higher filtering level?

That could be right then. Changing the time interval between reads could affect the ROR calcs. Do you know what sketch is loaded onto your newer TC4C?

Below is a snippet from the Roastlogger Sketch user.h file showing the values you could try adjusting. The aArtisanQ_PID sketch uses the same variables.

Download source  Code
// use RISE_FILTER to adjust the sensitivity of the RoR calculation
// higher values will give a smoother RoR trace, but will also create more
// lag in the RoR value.  A good starting point is 80%, but for air poppers
// or other roasters where BT might be jumpy, then a higher value of RISE_FILTER
// will be needed.  Theoretical max. is 99%, but watch out for the lag when
// you get above 95%.
#define RISE_FILTER 85 // heavy filtering on non-displayed BT for RoR calculations
#define ROR_FILTER 80 // post-filtering for the computed RoR values

It was preloaded by Jim back in mid 2013 and I added Roastlogger at that time for my gas fired drum roaster.

Unfortunately, I don't currently have any of the downloads I used for loading my old TC4, on my computer anymore.

The TC4 is running aBourbon. Can someone give me some tips on what I will need to load on to my laptop in order to be able to view the user.H files to be able to change rate of rise filtering settings?

It's been so long since I've set up any of my TC4s, it's like starting over again. limb

I do not know about the simple possibility,

You can use the windows notepad program to view and edit the user.h file. Right click the user.h file and select "open with" and then select notepad from the list of programs.

I probably misunderstood the question.

NotePad++ is a free download that makes a great editor for all Arduino files.

You can load one the Arduino IDE versions but beware, You are probably running all the older libraries so I would stay below 1.67. Now, if you want to do a total update, sketches, libraries and all, I would go ahead and download the latest version IDE.
If you do this, I would strongly recommend you do everything on a USB flash drive and not change anything with what you are using now. That way you can get everything setup and make sure it compiles before you try down loading it into the TC4. Start messing with your existing (old) stuff, and you regret it for a while.
I keep and extra TC4 setup and a (Arduino) flash drive I make my changes and updates on to test them before I download them into my main roaster controllers or make any changes on the main programs on my computer.

There are a couple of changes to RoastLogger that if you are using a fluidbed/air roaster that totally make it worth updating. The first is I Talked Tom into changing that 60 second delay before the PID activated, now you can select no delay or the 60 second delay. The second is the fan automatically goes to 100% and the heater goes to "0" when you eject the beans. Now, the bar scale in RoastLogger will still show a percent heat, but if you have a display on your TC4, you will see it drops to zero.
Apparently people were having problems with using A/C fans (which I've always used with no problem) but he has included a user.h for the A/C fan users.
