printf format

[Guest3]

I'm receiving this data per my serial pc connection but am getting wrong formating on my LCD and i can read just the first string (0xC1).
I know i have to include the space but don't know how

example:
0xC1 0xB3 0x21 0x2B 0x51 0x1B 0x2B

i'm using the:
printf(lcd_putc,"%c",PT);
delay_ms(1000);

result on LCD:
0xC ( without 1 and other data)

One more thing. If i can correct the formating and if i can get all data, then what should i do to erase all that data (after 0x2B) so i can receive new and changed one ?

thank you for reply.
I construct my question a bit wrong.
What i mean was, how to know when is the last character.

I know for now that i will get cca 8 "packages" of hex data and after last one i have to clean the lcd. I can not check for the last character because they are different each time so i guess i have to make some array and then make the check when the array is full ?.

What do you think, why i cant read all of the data ?

OK. but...

void main()
{
char c;
lcd_init();

while(1)
{
pt = getc();
printf(lcd_putc,"%x",pt);
delay_ms(1000);
}
}

INPUT:
0x21
0x3C
test

OUTPUT:
0x2
0x3
tes

Why ?

[PCM programmer]

Post a complete test program. Post the #include, #fuses, #use delay()
and #use rs232() statements. Post the main(). Don't post the LCD
driver. I don't need to see it. Just post the #include statement for it.
Post all your variable declaration statements.

The program should be short.

It must also be compilable with no errors.

Your code has a 1 second delay in your receiving loop.
While this delay is in occurring, you are not reading characters from
the hardware UART's receive buffer. If new characters come in
and you don't read them (because of the delay), you will get an
over-run error and the characters will be lost.

What is the spacing (in time) between the incoming bytes ?

When you use "%x" or "%x ", you are sending out 2 or 3 characters
for every one that comes in. This can cause a loss of incoming
characters because the code has to wait in a loop for the UART
transmitter buffer to become ready to accept another character.

Look at the Ex_sisr.c example file. It shows how to use the #int_rda
interrupt to receive the characters during an interrupt and to put them
in a buffer. Then your main() program can check to see if characters
are available in the buffer, and get them from there.

When you use this method, the receiving of characters is not affected
by delays in the main program. That's because it's done by interrupts.
