Crate tudelft_nes_ppu
Source - Buttons
- A struct containg all the buttons for one controller and whether they are pressed (
true) or not (false) - Ppu
- Emulating an NTSC PPU chip
- Mirroring
- Vram has 4 banks, while there is only memory for 2.
That means that two of the banks are copies of the other two
- PpuRegister
- There are 8 PPU registers, available to the cpu.
- CPU_FREQ
- CPU frequency constant. This assumes NTSC emulation (instead of PAL).
That’s also what’s emulated in the rest of the ppu.
- HEIGHT
- The width of the NES output video signal
- WIDTH
- The height of the NES output video signal
- Cpu
- To use your cpu with the provided PPU library, you need to implement this trait for
your CPU.
- run_cpu
- Runs the cpu with the ppu. Takes ownership of the cpu, creates
a PPU instance, and runs the tick function at the correct rate.
- run_cpu_headless
- Runs the cpu as if connected to a PPU, but doesn’t actually open
a window. This can be useful in tests.
- run_cpu_headless_for
- Like
run_cpu_headless, but takes a cycle limit after which the function returns.
