hi! could anyone give their input on my previous post about timer and

pleaseee...
my program seemed to just run first the thread then when it encounters
error on the thread that's the time that other part of the program got
the chance to be executed
even the timer even is not execute
a simple question regarding threading and timer:
if i put my timer control inside the thread, will the thread be exited
every time there is a timer event???
please help...

You could try helping yourself. Insert some print statements at salient
points. [see examples below; you'll need to get the indentation
correct, of course] Try to understand what is happening.

You've had far too much help already for a school project. Asking for
someone to write the code for you is "over the fence".

No he doesn't mean that at all. All it means is that minor scuffles
have broken out among the spectators. Don't worry about them, batons &
water cannon will fix them; you concentrate on the foo

@ sir Peter
so you mean that it is correct (at least on the unpack() part)
when i run this program on IDLE , Python 2.3 (enthought edition),
nothing is outputted on the shell, until i decide to close the shell,
wherein it tells me if i would like to kill a process...

Isn't this unpack rather redundant -- assuming ser.read(1) only
reads one byte, then rx_data1 and rx_command would be identical.
Brain fart... unpack converts the raw

the assembly program for the microcontroller is created by a
classmate. he based the protocol for the serial program from a
protocol he found in the internet. unfortunately, i can't find the
fpdf file, guess i'll just ask him later when he comes back.

this is not working, what is wrong with this code?? what it "should"
do is find first the command "70" then read the remaining 9 bytes once
the command was found:
rx_data1=0
while (rx_data1 != 0x46):
rx_data1 = ser.read(1)
(rx_command) = unpack('1B', rx_data1)
rc_data2=ser.read(9)

the hardware is a school project that uses a microcontroller for "light dimming"
the message command "67" will tell the microcontroller (PIC16F877) to
do a command (to control the intensity of a lamp)
the message command "70" should tell the GUI that the microcontroller
has started transmitting.

If so, that's 6 bytes, not 18:
