Hi
I have made a auto dir ctrl in a 11U14 and has now move it to a 1225/321, but does work.
My code is
  LPC_IOCON->PIO2_0 &= ~0x17;
  LPC_IOCON->PIO2_0 |= 0x05;      /* UART_DIR or UART_RTS(HB1) as direction control. */
  LPC_UART0->RS485CTRL |= RS485_DCTRL|RS485_OINV;
  LPC_UART0->RS485DLY = 100;// Delay of DIR Pin
Nothing at all happens on the pin when transmitting I tried flikering with the pin it works fine.

Any one that can see what i do wrong ?

Best Regards
Lars
