You can connect an I2C device to the board. The SDL and SCL pads are in the lower-center part of the board and are labeled.
You will have to do lots of coding to change the firmware to work with an I2C display. I suggest you create a new object like Display that controls the I2C device. I won’t be able to give you detailed help on this, as it would be a big project.
No, I’m afraid that video processing on an Arduino is limited to sensing the brightness of the pixel, not the color. I don’t know of a way to do it.
There is obviously a real need in the market for more video processing/generating tools.-Mike
Yes, you can control external devices by connecting a relay for either defuse or detonation case. See https://nootropicdesign.com/game-timer-pro/manual/#relay

I don’t know how you are compiling it, but make sure you specify the board as an Arduino Uno. This code is just normal Arduino code for an ATmega328 MCU.
The compilation error on line 980 implies that you are compiling for a different architecture.
#if defined __AVR_ATmega328P__
lowPowerBodOff(SLEEP_MODE_EXT_STANDBY);
#else
lowPowerBodOn(SLEEP_MODE_EXT_STANDBY); <- line 980 #endifAnswers to some of your questions:
1) yes, there is a 6-pin serial header that can be used with any FTDI serial adapter to upload code. There are plenty of images on our website that show this at the top of the board.
2) yes, settings are remembered in EEPROM. You don’t have to redo all the settings.As for changing the code, you will have to study the code and figure out what modifications you need. It will not be simple for me to tell you what to change. I’m available to do custom coding for a fee if you would like: https://nootropicdesign.com/store/product/custom-programming/

Hi Kevin,
The output jack is not directly connected to an Arduino pin. It is connected to the digital to analog converter (DAC) chip.

Hi wimbo,
Hmm, there must be a connectivity problem for the SRAM chips or the SPI select pins for the chips. I have never had this problem before.
Can you send good pictures of front and back of board to support [at] nootropicdesign.com? I’ll take a look.Debugging is difficult because the code runs really fast. Did you add debugging inside the ISR function? That won’t work. You can try reducing the sample rate to see if that helps. That will give non-ISR code more time to run.
It would require a total rewrite because the video generation library (TVout) is written in AVR assembly.
I would like to design a new board (not a shield) from the ground up using a faster microcontroller but I just don’t have time. It’s a ton of work to develop a new product. Maybe someday.
The Lumazoid code is not going to work on an 8MHz microcontroller. A .hex file compiled for ATmega328 cannot be loaded onto an 8MHz Nano. If you want to use the source code, you will need to compile it for the target, but 8MHz is not fast enough to perform the audio analysis.
Why don’t you just buy the product from me? I did the hard part for you already.
