Help from an admin or anyone familiar with the PD board and the BS2p40 chip?
Hello all,
This is a continuation from a previous post which basically asks...
Can anyone please send me some code for the BS2p40 chip to flash two LED's on the Professional Development Board and have them connected to one main port and one aux port!
I just got my 40 chip and I thing·it maybe a bad one or I am doing something wrong on the hookup!
I need some code that can test each port on the main and aux sides that will flash some LEDs to prove the chip is working correctly!
Also I need the correct hookup instructions for the code!
The chip identifies but thats it.
Thanks in advance!
Joe

·· In your previous thread (linked below) members trying to help you asked you questions in an attempt to help you in your original thread.· Please supply the requested information so we·can try·to help you further.· One other thing you can do is check out the StampWorks manual (linked below) which contains examples of blinking an LED on the PDB.· Your code would essentially be:
You can connect the P0 from the BASIC Stamp to the LED connection on the PDB.

Is there something else I can try or should I send it back???

I would like some detailed code and setup instructions to hook up two LEDs on the PDB to use two ports; the main port side and the Aux port side!
I don't know where the hookups for the AUX side are?
Example; hook wire to RC7 or P15 to R1 to LED to Ground...
and the code to go with it!

·· There is a table in the PDB Manual which explains where each pin on the BS2p40 goes to on the board.· Please see that manual and remember you cannot have an SX-28 plugged into the board at the same time.

assuming you have a resistor on pin 0 on the main side P0 going to an LED, whereas the LED is connected to VSS on the other side, and, you have a reistor connected on pin 0 off the AUX side(pin21), X0, going to the LED and the other side of the LED going to VSS:
You should specify variables for pins using MAINIO and AUXIO to tell the pins what they are connected to:
MAINIO
MainSidePin0 VAR OUT0
AUXIO
AuxSidePin0 VAR OUT0
Main:
MAINIO
MainSidePin0 = 1
Pause 500
AUXIO
AuxSidePin0 = 1
Pause 500
MAINIO
MainSidePin0 = 0
Pause 500
AUXIO
AuxSidePin0 = 0
Pause 500
goto main
·· Just to clarify, if you do not specify which bank of I/O MAIN is assumed.

Thanks to everyone for all their help!!!
I will be having some fun testing tonight!!!!

Just some clarification... I tried the following code and it worked!· So I know the chip is ok!· thanks!!!
'·{$STAMP·BS2p}
'·{$PBASIC·2.5}
DO
··HIGH·0
··AUXIO
··HIGH·0
··PAUSE·1000
··LOW·0
··MAINIO
··LOW·0
··PAUSE·1000
loop
BUT.....................
When I tried the next program I couldn't get it to work...
MAINIO
MainSidePin0 VAR OUT0
AUXIO
AuxSidePin0 VAR OUT0
Main:
MAINIO
MainSidePin0 = 1
Pause 500
AUXIO
AuxSidePin0 = 1
Pause 500
MAINIO
MainSidePin0 = 0
Pause 500
AUXIO
AuxSidePin0 = 0
Pause 500
goto main

Can someone please explain to me the port configurations on the BS2p40 chip.
Please see attachment of the p40 chip layout!!!
Can someone tell me the matching ports on the BS2p40 chip to the matching ports on the Professional Development Board?
I see RC...· and RB... and RA... but I don't·know what ports these are on the BS2p40 chip?
I know I have 15 mainIO ports and 15·AuxIO ports but what does that mean when someone says connect P21 to LED etc...?·
I would like to get the above code to work but need help on connecting the wires and understanding all the new ports available to me.
thanks
Joe
To add to the above comment...
If you look at the chip pdf file you will see P0 to P15 and X0 to X15...
These are what I am trying to match the RC, RB, and RA·ports on the PDB board and are these the AUXIO ports?
thanks again,
Joe
