BK-0010 Emulator (using STM32F407 microcontroller)
- Emulate BK-0010
- Load file in .BIN format from SD card
If you want to try my project, this is the only part that you need.
| Hardware | Qty |
|---|---|
| Black F407VET6 board | 1 |
| VGA connector | 1 |
| PS/2 Keyboard | 1 |
| Power supply 5V DC for keyboard | 1 |
| Resistors 470 Ohm | 3 |
| Resistors 680 Ohm | 3 |
| Resistors 2.2 KOhm | 2 |
| Resistors 3.3 KOhm | 2 |
| Breadboard | 1 |
| Jumper wires | 18 |

| G | Ground | VGA Ground (5,6,7,8,10), '-' of passive speaker |
This project uses several libraries (in addition to HAL drivers from STMicroelectronics):
- To display video using VGA: https://github.com/cbiffle/m4vgalib (which requires https://github.com/cbiffle/etl)
- BK-0010 emulator: https://github.com/emestee/bk-emulator
- FATFS for SD card: http://elm-chan.org/fsw/ff/00index_e.html
- Load / save files in .COD format
- Save snapshot
- Measure emulation speed and see if it needs a slowdown
- Sound
