This video shows the test interface between a Sparkfun Micro OLED breakout board and its library with a Winbond 1 MB Flash ROM and its library by Adafruit, sharing the same SPI bus; a Teensy 3.0 (the only 3.3 V compatible device that I had lying around) waits for a button press; when the button is pressed it queries the ROM for its max. capacity and shows that value on the OLED, then writes numbers 0 to 255 on the ROM starting from address 0, and finally reads those values from the ROM displaying them on the OLED while reading. This is a test performed to check correct functionality of both libraries and devices when sharing the same SPI bus for the BitMasher project.
