USB hid examples don't work on LPC2387

Sergey Sergeev

Hello.

I have a SK-MLPC2387 board with LPC2387 processor and here some problem with it. I downloaded Keil HidUsb examples for LPC2378 and loaded it (hex file) in LPC2387 using latest version of FlashMagic utility (ISP). The loading was sucessfully finished and veryfied, then I disconnected board. When I connected the board again (after ~ 20 sec), operation system (Win 7) didn't find new device looks like USB cable was disconnected. The power LED is on, and I don't know where source of problem..

    Aha, forget to format the code

    usbhw.c

    void USB_Init (void) {
   ...
   ...
  /* The SoftConnect pin for LPC2300 on USB_U1 doesn't work for now,
     make it GPIO and make it low to turn off pull-up on D+.
         Once it's fixed, make #if 1 and set it as SoftConn Pin. */
//#if 1                                     /* MCB2300 V4.0                 */
#if 0                                     /* MCB2300 V4.0                 */
  PINSEL4 &= ~0x000C0000;                 /* P2.9 USB1 SoftConnect        */
  PINSEL4 |=  0x00040000;                 /* PINSEl4 18.19                */
#else                                     /* MCB2300 V3.0                 */
  PINSEL4 &= ~0x000C0000;
  FIO2DIR |= (1 << 9);
  FIO2CLR  = (1 << 9);
#endif
   ...
   ...


void USB_Connect (BOOL con) {
//  WrCmdDat(CMD_SET_DEV_STAT, DAT_WR_BYTE(con ? DEV_CON : 0));
  if ( con )
     FIO2SET  = (1 << 9);
  else
     FIO2CLR  = (1 << 9);
}
