Hello!

I'm interested in how to turn on and turn off LED which is connected on Serial (COM) port on computer. I want to use Visual Studio 2005 for turning on and turning off the LED, and for receiving I want to use PIC16F84A which is programmed in PICBasic. If there is any method without using PIC, also tell me. Thanks!

Hi,

YES ... its name is DS 2405 from Dallas ...

you can use either your PC or a small µP to drive them ... Dallas also give a PC driving soft on its site ! ( "One Wire viewer" )

Hi,

In my shops there aren't DS2405. I want to control my LED on COM port with VISUAL STUDIO 2005. How to do this?

I Think Mel ( Melanie ) posted a nice PIC program to do that ( written on a table towel ! if my souvenirs are right ).

VB 2005 will still be your part ...

Might be retrieverable through the SEARCH function of this forum.

I don't understand again. How can I control this circuit with PC with software programmed in Visual Studio 2005?

You write a program on you PC to send a command via serial.
Have the PIC programmed to look for a certain command from the PC.
If the PIC likes what it sees from the PC...

Could he be referring to driving an led directly from a serial port? :eek: That's kinda how I read his first post... shift register, maybe? (his post said without the pic, from vs2005). Maybe he needs to word-up on bit-banging the parallel port instead?

Just my $.02
