18f25k22 hserin

[jackberg1]

Hello,

I've tried to use the Hserin with no success, let me explain,

I used the example from the PBP3 compiler reference manual p:150

and scanning with hand barcode scanner nothing show or random character show up on the serial terminal.

the scanner is set at 9600,8,1,n and it's working on other application

I'm looking for the code to wait until I scan a code then it send to a serial port and come back waiting for the next scan.

is there someone who can help.

thanks to everyone

I don't have the manual in front of me now, but I think that you are missing some parameters in the HSERIN command.

[jackberg1]

the manual is in PDF format.

Let me know what is missing when you can.

from the data sheet only 3 setup as to be done for receiving.

thank you

Check this thread.

[rsocor01]

Also, HSERIN starts saving the variables after the WAIT requirement has been met. In your case, it will only save 11 numbers instead of 12.

[jackberg1]

Thanks for your time, I'll look at it, also I did used a timeout label (hserin 5,MAIN,[STR AARRAY\12])
still no result.

Thanks again.

[jackberg1]

I rectified it (hserin 5,MAIN,[STR AARRAY\12])

[jackberg1]

here's the code from today post:

HSERIN [wait ("0"), str AArray\12]
serOut2 PORTB.0,84, [str BArray\12,13,10]

[richard]

Works ok for me if BArray has something printable placed in it

perhaps u wired it up incorrectly

even this

[amgen]

....."0" is decimal 48

thanks to everyone involved to help me on this project.
I tried about every way to setup the HSerin1,2
still not working.
I'm realy suprise since these HSerin command are part of PBP3 for at least 15 years
and today in 2025 cannot find any reliable sample codes.
even the PBP3 examples does not work at all for my setup.

I had 1 rs232/ttl scanner bad (intermitent power on the rs232 rail)
connected another one and the only easy way to make work it's
with the code below.



MAIN:


'--------------------------------------------
serin2 PORTB.0,84,50,MAIN,[STR AARRAY\12]
serOut2 PORTB.1,84, [str aarray\12,13,10]
serOut2 PORTB.1,84, ["Done!",13,10]
'--------------------------------------------


GoTo MAIN

[richard]

works as expected
only slight change was to move serout to portb.7 to suit my pickit2 debug uart tool and put something printable
into BArray

what doesn't work are code snippets and failure to provide connection details [ schematic]
and even a description of what happens versus what you expect to happen

Hello everyone, and thank to all for helping me

this case is solved!


1st

the GM65 scanner Tx/Rx line are at 3.3v not at standard 5V TTL logic, so I add a BSS138 between the Tx and the Rx (HSerin) of the PIC

2nd

I like to thank also BrianS (HSERIN issue with a 18F452 and IF THEN statements or Case statements (https://www.picbasic.co.uk/forum/showthread.php/24234-HSERIN-issue-with-a-18F452-and-IF-THEN-statements-or-Case-statements))


while reading about his case I took part of the HSerin setup and added to my program, first try work just fine on HSerin/HSerin2.

Many thanks richard.

Take care.

[richard]

No code error , no compiler deficiency. as suggested in post #9 its wired incorrectly

who would have known

[jackberg1]

Specialy when the GM65 user manual mention TTL logic level, yes the DC supply is 5V, for the USB / UART ports.

but it's not specify 3.3V Tx/Rx output line.

Learning everyday like everyone here.
