* NuEVI also includes on the [Filters](https://github.com/JonHub/Filters) library by Jonathan Driscoll, but that is no longer an external dependency.
For the SSD1306 library, the Adafruit_SSD1306.h file needs to be edited to prevent it from lowering the I2C speed.
Change this:
Adafruit_SSD1306(uint8_t w, uint8_t h, TwoWire *twi=&Wire, int8_t rst_pin=-1,
uint32_t clkDuring=400000UL, uint32_t clkAfter=100000UL);

After uploading new firmware, you may need to reset the config memory of the NuEVI. It's a good idea
to do between version upgrades, since the config parameter format often changes. To do this, press
