parallel/serial interface

[syeda amna]

hi

i m working on home automation project using ATMEGA16L. the output of the controller is connected to 8 different devices. now i want to monitor the whole system on PC. such that which devices are on?? for how long the devics are on.
for this i want to interface through computer, which interfacing will be better or suitable for this? which software is better??

plzzzz help me

Most modern PCs don't have a parallell port, so if I was you, I would use a serial interface which is easier to come cross in the modern world.

thank you, would you like to tell me about is VB6 is better for serial interface. i come across a lot of difficulties during interfacing and still not unable to achieve my task.

Sorry, I am not a programmer and have never used VB (refuse to touch Microsoft products for development).

i use vb 2008 for my serial communication project..actually the software will sent the ascii code..so u should program the micro c to reflect with the ascii..for example your vb sent character "a" and the ascii value = 49(if i am rite):

(i use BASIC for my PIC program)

dim datain as byte

start:

datain = hserin 'receive the data to variable data in
if datain = 49 then PORTB.0 = 1 'turn on portb.0
else
PORTB.0 = 0 'let the portb.0 off when data not equal to 49
end if

goto start

I would like to Tx/Rx data thru serial port thru C programming.
Need guidance
Thanx

Hi,

If you plan to use serial port you'd better use a USB to RS232 converter. Thus you can monitor your system even using you laptop.

For programming use VB or Delphi. Search there is a lot of threads on this issue on edabaord.

Check this one for exemple.

hello adeel.sid ,
an rs232 library is available for windows and other platform usage at:
https://github.com/ynezz/librs232

it has both c and lua codes.

hope you can utilise it for your requirement.

Hello Sriz.. & Adva..
I want to send and loop back the Tx data to Rx line of RS232 thru C code (for understanding C-interface wd 232 as my first program of interfacing thru C)

Adeel
