BS1 Output to Screen

edmondfox

With the Basic Stamp 1 am I able to output data to the screen? When I identify the stamp in the programmer it says loopback and echo are 'No'. Here is part of the code where I am attempting to output to the screen:

SEROUT RxD,N2400,("input here > ")

However nothing shows up when I connect to the comm port the stamp is on, even after powering it off and then back on.

*** Debug works fine but I am unable to enter data at the prompt output using Debug.

Any ideas?

What is your question ?
You seem to be able to output data to screen since you added DEBUG works.
So is it getting some input from the debug windows ?
Well, the DEBUGIN command is a PBASIC 2.5 feature. Not avaible to BS1.

But obviously you know the SERIN instruction.
I wonder..are the parenthesis necessary ?
Because when I check the manual, it says :

Basic Stamp Manual said...
The example below will receive a single byte through I/O pin 1 at 2400
baud, 8N1, inverted:
SYMBOL serData = B2
SERIN 1, N2400, serData

and....no (..).

However, did you try to use the Windows Hyperterminal ?

If you want to do general-purpose serial I/O between a PC and the BS1 then you need to use two of the BS1's I/O pins for this (one for SERIN, one for SEROUT). While it's best to use a MAX232 level shifter between the two, you can get away with a direct connection by using a 22K resistor in the SERIN line. The manual and help file show the direct connections.
