Serial data

[Guest2]

Is there some program which i can use for sending serial data from PC to my demo board ?. I hate to use hyper terminal and i need constant data transfer which will loop some defined data.

Any suggestions ?

this one is great:

I'm using the terminal that you have suggested and i must say it's quite simple but effective.

As example i have choose the ex_sisr.c example and this is what i get:
As delay time i have set 5 seconds.

I compile and run program on the demoboard and on the lcd display you can see "running".

I open the terminal program ( i tested with the hyperterminal too ) and i send some chars... "test" . After cca 5 second i get message Buffered data => and that is that. There is no test chars, no garbage chars etc.
How come ?

The serial port monitor is great ! :-)

I can see that the process has started and i can see that data has been send, so the problem is in the software. Ok.

#include <16F877.h>
#fuses HS,NOWDT,NOPROTECT,NOLVP
#use delay(clock=20000000)
#use rs232(baud=9600, xmit=PIN_C6, rcv=PIN_C7)
#include "lcdDriver.c"

:
:
:
do {
delay_ms(3000);
printf(lcd_putc,"\r\n Data ");
while(bkbhit)
putc( bgetc() );
} while (TRUE);

Is the problem in lcd output ? I can see the "Data" text but that all.
Did someone used this example ?

I have just tried the latest Terminal version.
As for me and my USB-RS232 adapter, the latest version of Bray's terminal can't send any data to the serial line.
It freezes immediately when I hit the Send button. I therefore use an old version released in 2006.

Do you have some other software example which i can test cuz i think that serial connection is OK. ?

I established the connection but there in problem in formating, at least i think so...

I want to enter HEX value thru my keyboard and then i need to receive the same one in the HEX format. So i try with printf(lcd_putc,"%x",c); and this is the LCD output:

Keyboard input: 10
LCD output: f8

Keyboard input: 11
LCD output: f8

Keyboard input: 15
LCD output: f8

Keyboard input: 25
LCD output: fe

Is this just the formating problem or is this something else ?

One more thing, that i forget to mention.

If i dont want to type the characters, if i just want to read the whole
string, can i pass this data as like thru file transfer ?

If so, then how to read this data on my picdem ?

E.g.
This is the text that i have writen before and this is what i want to see on
my LCD. 0x1,0x2,0x3,0x4, bla bla bla.
