A Pico board can however allow better control at lower frequencies within the typical AM radio station (~1000 KHz). While square waves are well-suited for frequency-modulating any PCM audio file (ignoring the unwanted harmonics), they cannot be used well for amplitude modulation. They can only encode ON or OFF instead of different audio amplitudes (think 1-bit envelope). Alright, no emitting arbitrary “.wav” files. We can at least emit a single audio frequency at a time using On-Off Keying. Let’s make some retro game sounds!
In a bitmapped b64 encoded image, approximately speaking, the first few pixels and the first few characters of the b64 string are related, and the same is true of any other chunk of the image and the corresponding chunk of the b64 string. Approximately.，详情可参考体育直播
