usb65 - 6502 USB host and device drivers

The usb65 USB drivers is an attempt in creating a set of cross-platform and cross-hardware USB drivers for the 6502 processor. The aim is to make them generic enough so they can be reused in many 6502 computers.

Currently supported functionalities:

• Keyboard (host+device)
• mouse (host+device)
• hub (as host, can enumerate devices connected via a hub!)

Currently supported hardware:

• SL811HS (host+device) via processor bus interface
• MAX3420 (device) via an SPI interface
• MAX3421 (host+device - device is same as MAX3420) via an SPI interface

Currently supported platforms:

• BASIC4 PET with
  • CBMUSB userport USB interface (MAX3421 for host)
• CS/A "Fat40" PET replica with
  • NETUSB 1.x board (2 SL811HS for host and device)
  • NETUSB 2.x board (MAX3420 for device + MAX3421 for host)
• Commodore PET with CS/A adapter
  • (tested only with NETUSB 1.x)

Future plans:

• code cleanup
  • more generic assembler
  • extract common code
  • separate platform specific code
• more supported platforms
• more functionalities
  • RS232 via USB
  • mass storage device (USB stick)
  • Network (ethernet?) via USB
