PurrFX project update 19
Project status overview as of September 20, 2020. Commits : September 20, 2020. Development has gone far enough and it's time for some really interesting updates! Let's start with the fact that the library now has classes and functions for converting register values to sound frequencies. For example, for the Pulse1 channel, registers $4002 and $4003 are responsible for the sound frequency. Their combination gives us an 11-bit value, which, according to a special formula, is converted into a reproducible sound frequency. Also, the library (using the CNote class) allows you to convert the frequency of a sound to a note, i.e. into a specific piano key. You can use this feature to render notes in one way or another (for example, on a piano roll). The CNesState class allows you to do something like the simplest emulation of the processor's work, accumulating the values of the registers. Thus, it is possible to simulate playback of track data even without using CNes cla...
