If using any Arduino with 5V signals, you’d need to level shift them down to 3.3V.

To anyone attempting to use this product with a 328p:

I’ve created a branch that supports 328 things. It’s up to you to divide the signal voltages down to 3.3V though.

Direct link to branch zip: https://github.com/sparkfun/SparkFun_TeensyView_Arduino_Library/archive/Multi-platform.zip

This includes an example specific to the 328, however, the template, screen demo, and high speed examples should work.

Under “Documents” lists “Arduino Library” so I ordered 2 thinking I could use these with any of the many Arduino boards I have kicking around. Just sat down to run the demo and find that the library won’t run on regular “Arduino” hardware? Not good. Now what?

Just found that the “Micro OLED Breakout” P/N: LCD-13003 uses the same controller (SSD1306) and has Arduino library. Maybe that library can be used.

The “re-wording” would be beyond me, and quite few others, I suspect. Sorry to mess with the catchy product name… (^_^) … but a library for us Arduino folk would be very welcome! Looks a neat device. Perhaps if you offered a free “development sample” to one or two with the skills?…

Pehaps the text at the top of…

https://github.com/sparkfun/SparkFun_TeensyView_Arduino_Library

… should be expanded to explain that while the library is fine for the Arduino IDE, the code will only work if the target board is a Teensy?

Sure! The Teensy is just a SPI master with data/command control line added on. It’s all at 3.3V. The library uses the Teensy style SPI settings though, so it would have to be reworded (see hardware.cpp in the library).

Schematic shows the spi lines are all that is needed, all you would need to do is hookup spi to an arduino and communicate with the OLED.

While of course a “mere” Arduino, say the Pro Mini, could not generated and plot a real-time frequency display for two audio channels, does this product actually NEED a Teensy, if the user is satisfied with “just” some text?? Library issues? What? It interfaces via a simple SPI… or is it I2C?… interface, after all?
