BS 2 Interpreter Chip

Rino

I want to integtate the BS 2 Interpreter chip to my circuit board (PBASIC2C/P
I do not have a pin out list to compare it with the BS2-IC Module that I am presently using.
I need to know where pin 0 to pin15 are.
Where can I get that information?

I cannot open the Gerber files. What software do I need to open that?

Good question, I can't open them with XP or Vista. Can you get the PIC interpreter pinouts from the PDF file? It shows the 28-pin DIP and pinout header connections.

Yes, I can open that but I do not know what the pins correspond to. I am used to I/O pins 0 to 15.
In the schematic we have RA0 to RA3 then RB0 to RB7, then RC0 To RC7. Where are I/O pins 0 to 15?

Thanks

Trace 'em down from the PC pic at http://www.parallax.com/desktopmodules/catalookstore/ImageViewer.aspx?link=Images%2fProd%2f2%2f272%2f27291-L.jpg&desc=BASIC+Stamp+2+OEM+Module+(Kit+Form)&PortalID=0&viewerid=-1&mid=-1

Pin 20 on connector X1 is Vdd, corresponds to pin 2 on your interpreter chip.
Pin 19 on X1 is Vss, pin·4 on your interpreter chip
RB0=P0
RB1=P1
...
RB7=P7
RC0=P8
RC1=P9
RC2=P10
...
RC7=P15

The BS2 OEM uses this chip. There is pdf file with the schematic on the Parallax store page for the PBASIC2C/P interpreter chip. This schematic shows exactly how to connect the chip.
