Already running into issues.

max serial baud is 9600, but in other code I can run 115200. Why?
- Might be a function of these other errors.
something in loop() is breaking OLED display in setup().
- I assume it's trying and failing to read something and getting stuck. I should wait until I have the encoder and the Si5351.
- Could even be confusing the OLED for the Si5351 since those are both I2C devices.
  - https://arduinogetstarted.com/faq/how-to-connect-multiple-i2c-sensors-devices-with-arduino
  - SI5351 board is 0x60 or 0x61 (https://learn.adafruit.com/i2c-addresses/the-list)
  - OLED is likely 0x3C or 0x3D (ibid.). 0x3C is used in my example code that works.
If I comment everything out in loop(), the screen seems to work (but shows noise instead of what I want).

Here's how to set the I2C address for the Si5351: https://github.com/etherkit/Si5351Arduino#alternate-i2c-addresses
Si5351 si5351(0x61);

If I can't get the current code to work, there is this project which seems to do everything except the Polyakov mode: https://projecthub.arduino.cc/CesarSound/10khz-to-225mhz-vforf-generator-with-si5351-version-2-acdc25

Polyakov mode would "just" mean displaying a frequency that is twice what is actually being used in the receiver circuit.
