-/* This particulary board not have paralell port but have a special LCD header
- * where can connect an HD44780 display.
- * This port called IOSC0 port, and is write only, this port control the
- * 4 leds on board too.
- * Because its a write only port you can't control leds outside lcd driver
- * or inverse, for this added the socket controlled leds. To send led status
- * simply open an UDP socket and send to localhost 127.0.0.1 port 3333 one
- * byte or more anyway only the first byte 4 low bits used the others is
- * cleared and ignored bit0 = Led1 ,bit1 = Led2 ...
- * This socket polled via timer callback, for detail see at drv_RB_start()
- * I add at to end of this file an example!
- * If you don't want coment #define RB_WITH LEDS and this part will be ignored
- *
- * The connection details:
- * The IOCS0 port lower 16 bits connected as follows:
- * bit LCD LEDS
- * 0..7 data
- * 8 INITX
- * 9 SLINX
- * 10 AFDX
- * 11 backlit
- * 12 LED1
- * 13 LED2
- * 14 LED3
- * 15 LED4
- *
- * LCD male header:
- * 1 Vcc +5V
- * 2 GND
- * 3 RS (Register Select,AFDX)
- * 4 Contrast adjust (controlled) but how? if you know tell me not mentioned on User Manual
- * 5 E (enable signal, INITX)
- * 6 R/W (Data read/write or SLINX) not used connect LCD pin to ground
- * 7 Data 1
- * 8 Data 0
- * 9 Data 3
- * 10 Data 2
- * 11 Data 5
- * 12 Data 4
- * 13 Data 7
- * 14 Data 6
- * 15 Backlit GND (controlled) (IOSC0 bit 11)
- * 16 Backlit Vcc +5V
- *
- * If you using this driver and board and you have any fun device connected,
- * program or story :-) ,please share for me. Thanks.
