Serielle interface too slow

 

Pedro

Hi,

subesquent code lasts about 30 Seconds to the bytes the File of 30KBytes over The Serielle Schnistelle To Send
The Bautrate is on 57600 tuned
The cause is the commands WriteCom(porta_serie&,AUX$), if it auskommentiere lasts it 2 sec
To the word ENDE appear.
with the Baudrate, müssten about 5700 Bytes/second gesendet go, what on about under 8 sec with
30Kbytes ought to. what can made go it To speed, or make I what wrong?

greeting
Sato

var datei$ = "c:67123.DAT"
Assign #1, "C:67123.DAT"
OpenRW #1
anzahl% =  @BlockRead(Datei$, Bereich#, 0, FileSize(Datei$))
Close #1
ANZAHL% = 30929  BYTES
pos& = 0

While anzahl% >= pos&

    aux& = @Byte(bereich#,pos&)

    if aux& <= 15

        aux$ = "0"+@hex$(AUX&)

    else

        aux$ = @hex$(AUX&)

    endif

    WriteCom(porta_serie&,AUX$)
    @ComError(porta_serie&)
    Print #8,aux$
    inc pos&

endwhile

Print "ENDE"

Hello
where send You your data (which unit is the Empfänger)

I work too occasionally with the seriellen (but over USB) and there Have I each a *.DLL File The I anspreche and the The Schnittstellenparameter recognize (Baud, Parität, Stoppbit etc.)

If you me egg little More Information give, can I you Maybe help.

Hi,

The Empfänger, is a of me developed Platine with a Microcontroller the The data interrupt gesteuert assumes. on the computer is a USB/RS485 Adapter and the Platine get The data a integrierten RS485 IC How Max487. I can whom USB Adapter bagged let so the computer whom virtual Port opened can and the Platine Remove. to that XProfan further test the program and run by a Stopuhr can I insist the 30kbytes about 30 sec last. The Datenfluss can I too on the Led from the Adapter see. Fals I Writecom commands auskommentiere, go naturally The data not gesendet, but the Loop becomes volständig abgearbeite and whom drop lasts not time 2 sec
As I said, I can The File entire in my board received and reconstructed by the kontinuierten write the conceived Bytes on The SD ticket, The on the Platine is, only it lasts......

an idea moreover?

greeting
Pedro

E.T.
Würd I sooner on the Adapter / pertinent driver type. I had too time so one part, there watts from the Gegenstelle on the RS even always aborted, because the data simply too slow arrived are.
Adapter incl. gerätespezifischer driver ausgetauscht, and already hats functions.

...and the Adapter observes neither, if You the RS-unit abziehst ??
So my "mault", if it The data not "weiterschicken" can...
