woodstock . / Mbed 2 deprecated Nucleo_Ex06_EMU

I have ported my old project “pNesX” game console emulator to the nucleo.

Dependencies:   SDFileSystem mbed

Intro

I have ported my old project “pNesX” to the STM32 Nucleo. The pNesX is a NES emulator for the PlayStation that I have created 16 years ago!

Emulation part was almost without change, the sound part was newly added.

Parts

STM32 Nucleo F446RE
QVGA 2.2 TFT SPI (with the SD card slot)
Audio jack(TS or TRS)
USB Connector
Register 100k, 10k, 4.7k, 100
Capacitor 0.01uF, 2.2uF
Breadboard
Wires
Computer Speakers
USB GamePad

Limitations

  • Since the rest of the RAM is about 50kbyte, maximum capacity of the game ROM is about 50kbyte.
  • The length of the file name up to 32 characters.
  • The number of files in the folder is up to 100.
