Hi,

Today i get the VDIP2, im reading a lot about this part and how to use it with a pic http://www.picbasic.co.uk/forum/show...highlight=vdip like to thank especially to BrianT for is great job my code is based on is.
Here is the data from VDIP2 http://www.vinculum.com/documents/da...s/DS_VDIP2.pdf
Im very new at all this and i have a lot of concerns on doing this (the part is not very cheap 32€ im afraid to kill her) as i read from BrianT e have to reflash it and i do not now if i need to do the same a not clear how to and what firmware to put.
Ftdi do not suport very well me...
I to do not now if i need to put some resistors in the pic vdip2 connections?

My 1st idea was and is to connect a pic to a nokia 6230 with is original usb data cable and sending sms and macking calls..
Here my traing code

DEFINE LOADER_USED 1

define OSC 20   

Include "modedefs.bas" ' Include serial mode
DEFINE HSER_RCSTA 90h ' Enable serial port & continuous receive
DEFINE HSER_TXSTA 24h ' Enable transmit, BRGH = 1
DEFINE HSER_SPBRG 129 ' 9600 Baud @ 20MHz, 0.16%
DEFINE HSER_CLROERR 1 ' Clear overflow automatically


'bits 2 & 3 temporarily inputs
TrisC.2=0 'active LOW reset line to VDIP2
TrisC.3=1 'Cts# Flow control to VDIP2
TrisC.4=1 'Rts# Flow controlto from VDIP2
TrisC.5=0 'Led to see if pic and code is ok blink 3 times
TrisC.6=0 'Rx VDIP2
TrisC.7=1 'Tx VDIP2

B0 var byte

High portb.5
Pause 500
Low portb.5
Pause 500
High portb.5
Pause 500
Low portb.5
Pause 500

Start:
High PortC.2 'active LOW so not reset
Low PortC.3 'pull VDIP2 pin CTS low 
Input PortC.2 'from VDIP2 pin RTS
High PortC.6 'condition serout pin to mark state
Pause 5
HSEROUT ["AT", 13]

HSEROUT ["ATD=+351xxxxx000;", 13]

STOP

end
