tusb_drivers

Collection of custom host drivers for TinyUSB

I have not found a better way to implement access to non-standard class devices.

Got inspired by how tusb_xinput works and I did the same. This requires modification to tinyusb library.

If you know a way to access "vendor" class devices without modifying tusb please let me know.

Drivers

Densha De Go

Supports the PS2 "Type 2" device. More devices can be added but I don't have any.

GunCon2

Supports the PS2 GunCon 2 device.

Steel Battalion Controller (SBC)

Supports the Xbox Steel Battalion Controller device.

Using

Copy the src files to your installed tusb lib. I like to use put the files on the class folder.

Add to tusb_config.h

#define CFG_TUH_DENSHA 1
#define CFG_TUH_GUNCON2 1
#define CFG_TUH_SBC 1

Add to usbh.c:

  #if CFG_TUH_DENSHA
    {
      DRIVER_NAME("DENSHADEGO")
      .init       = denshah_init,
      .open       = denshah_open,
      .set_config = denshah_set_config,
      .xfer_cb    = denshah_xfer_cb,
      .close      = denshah_close
    },
  #endif

  #if CFG_TUH_GUNCON2
    {
      DRIVER_NAME("GUNCON2")
      .init       = guncon2h_init,
      .open       = guncon2h_open,
      .set_config = guncon2h_set_config,
      .xfer_cb    = guncon2h_xfer_cb,
      .close      = guncon2h_close
    },
  #endif

  #if CFG_TUH_SBC
    {
      DRIVER_NAME("SBC")
      .init       = sbch_init,
      .open       = sbch_open,
      .set_config = sbch_set_config,
      .xfer_cb    = sbch_xfer_cb,
      .close      = sbch_close
    },
  #endif

Add to tusb.h (and change the paths if needed)

  #if CFG_TUH_DENSHA
    #include "class/densha/densha_host.h"
  #endif

  #if CFG_TUH_GUNCON2
    #include "class/guncon2/guncon2_host.h"
  #endif

  #if CFG_TUH_SBC
    #include "class/sbc/sbc_host.h"
  #endif

Check the callback functions on the source file and implement them.
