Ian FIFO II has two I2S inputs, while the S/PDIF board has four. There will be five music sources in total, so, it would be ideal to have an integrated controller to work with the FIFO KIT.
There are no difficulties to develop a dedicated controller for the Ian FIFO KIT. However, I would prefer an open source, Arduino based project, because more people in this community can take part in. With the source code, everybody can make a controller on their own. We can set up a team to help nourish and improve this project. More fun will be had soon.
This is my plan:
1. Introduce a very small operating system, IanRTOS (It might be one of the smallest RTOS for Arduino). It has scheduled tasks management in non-block mode and can make a programmer’s life so much easier with state machine style C++ programming.
2. Write a C++ class for DFR0009 LCD KeyPad shield.
3. Write a C++ class for Ian FIFO and S/PDIF board.
4. Build a main sketch of the Ian FIFO controller with above classes
5. Run Ian FIFO KIT with this controller
6. Introduce possible IR remote control
7. Possible TFT Touch screen
8. Possible Bluetooth controller
9. Possible wifi based mobile controller
10. And much more!
The FIFO controller will look like this. Please see the following pictures for details. We only need an ARDUINO board and a LCD KEYPAD shield for now.
By following this project, you can build this Arduino controller by yourself, and then customize it and improve it.

TFT?
Hi Ian. Have you looked at dimdim's TFT shield for the es9018 (TFT HiFiDuino Code | Dimdim's Blog )? They are visible from far away if they are large enough! Helpful with the remote...

Hi palmito,
Thank you for the link. Pretty nice project. I bought a similar TFT/Touch shield weeks ago, but the color and brightness are not as good as standard LCD shield. I'm still looking for some really nice TFT/Touch screens for improvement down the road.
Please let me know if you have any recommendation.
Dimitris can also integrate my code and FIFO controller into his project. FIFO controller will be an open source project. All Arduino code will be published very soon.
Regards,
Ian
That is unfortunately very true for most inexpensive TFTs available to hobbyists. The best TFT that I own (picture quality wise) is this one from Adafruit, but I have trouble recommending it since it becomes pretty expensive pretty fast if you include shipping costs. But the colors are very vivid and the viewing angles are excellent.
A while back I purchased a low cost IPS panel from Ebay, one that promised very good viewing angles, but I haven't gotten around to testing it.
I would be more than happy to integrate your code into my project. I have only respect for your truly SOTA solution to jitter. In fact, the only reason I hadn't purchased one for my B3 was the lack of support for DSD.
Hi Dimdim,
Thank you so much. I’m glad that you are interested in integrating a FIFO controller into your project. I like your projects, very good jobs.
I’m very happy with standard TFT glass so far, such as 4.3” TFT/Touch panel. We used a lot of in our STM32 projects. Unfortunately it’s very hard to find them as Arduino shield. The only one I can source is this guy:
4D Systems | 4DLCD-FT843
The price seems not that bad, but still a bit higher for a DIYer. I don’t know if I could recommended it to you though UTFT doesn’t support. Just hope I had time to give it a try. But it seems I need to focus on my multi-channel I2S/DSD FIFO project, which you might be interested in.
My plan will be like this,
First build software architecture with IanRTOS, which is just a scheduler for now. But it can make my life much more easier with state machine style C++ programming.
Then, I will write a C++ class for DRF0009 LCD/KeyPad, which might be the simplest and most inexpensive way to implement a FIFO control panel. You can ignore/skip this step if you prefer a TFT/touch screen.
Finally, I will write a C++ class to control both FIFO and SPDIF board (will need 7 pins of Arduino) to make FIFO control panel a first run. With this part of source code, you can implement this FIFO control panel in your approach. It will tell you every details to run a FIFO KIT. Source code would be the best language to express a project
.I’m looking forward to your good news.
Have a good weekend
Ian
First step: Confirm IanRTOS code is working for your Arduion board
I think many of us are familiar with Arduino. To start building the architecture of FIFO control panel code, we need to confirm IanRTOS is running for your Arduino board first.
Please download IanRTOS.zip I attached at the end this post. Copy IanRTOS folder into your PC or Mac. You just need:
1. Run IanRTOS.ino from IanRTOS folder by Arduino IDE.
2. If LED on your Arduion board toggles every 1 second (please see the video), that means IanRTOS is working for you.
(Already tested on Arduino-UNO, MEGA 2560 and DUE)
If you are done, then we are ready for the next step.

We will need a LCD Keypad Shield, DFR0009, for the next stage, which can be fine at:
DFRobot LCD Keypad Shield for Arduino - RobotShop
or, some where else.
I'll post the testing code very soon.

I have to say: I find it totally rad to call a basic, fixed scheduler 'IanRTOS'.
Cool idea!
I have been working with embedded system design for many years, without a scheduler and tasks manager I can not do anything except "Hello,World!"
. That's why I wrote an IanRTOS for Arduino
.Regards
Ian
Hi Ernst,
Both of them (the two I2S and the hiden I2S on SPDIF) will be under control form this Arduino control panel
Good weekend
Ian
Second step: Make DFRobot LCD Keypad Shield working with your Arduion board
Please download DFRobotLcdKeyShield.zip I attached at the end this post. Copy “DFR0009Demo” folder into your PC or Mac. We just need:
1. Stack DFRobot LCD Keypad Shield on top of Arduino board (UNO or MEGA2560)
2. Run DFR0009Demo.ino from “DFR0009Demo” folder by Arduino IDE.
3. Press buttons on the shield. If name of each pressed button can be shown on the LCD screen, we are ready to go to the next stage: Ian FIFO control panel.
DFRobot DFR0009 LCD keypad shield can be sourced at:
DFRobot LCD Keypad Shield for Arduino - RobotShop

Hey Ernst,
you don't really 'run' Arduino sketches in the IDE, you edit them in the IDE and then run them on the Arduino.
You can 'compile' within the IDE by clicking the 'check-mark' button (called "Verify") and send to the Arduino via the 'arrow' button ("Upload") right next to it in the upper left corner of the editor window.
Does the sketch compile (verify) without errors?
If not, what errors does the IDE report?
Cheers,
Sebastian.
