C Program to Control Electrical Appliances

Are you looking for a free download, or do you want to purchase such a program?

Dear sir,

I kindly request you to send me the C Programme to control electrical appliances as a free download.

Thanking you sir

Having pics etc i presume you are not talking about household appliances where simple on off switches will be sufficient.

The max232 seems to indicate that you are looking at serial communication via the serial port.

You however need to supply more detail.

Does the system require any command codes or is the intention to use the control lines?

Is flow control required? (Hardware, software XON = XOFF)

Should the program receive data or feedback from the appliance?

Computer operating system?

thanks i really appreciate,i think you really know what am talking about here,and also thanks for the response,am actually talking about home applinaces and i really will be needing a program on this written in c language just for on and off of the electrical applinaces via serial port ...please kindly send all information you have on this as regards to the ealier stated components to bjshaine@yahoo.com

thanks

I am a Fortran, HP basic, Assembler and Pascal user. and never did C.

I have done some switching with the serial port. The easiest is to uses the control lines directly.

The following Assembler code can be used

MOV DX , 3FCH ; control register port 1

MOV AL,nn : switch value

OUT DX,AL : throw the switches

nn = 0 both off

= 1 DTR on line 4 on 9 pin 20 on 25pin

= 2 RTS on line 7 on 9 pin 4 on 25 pin

= 3 DTR and RTS on

Signal ground - line 5 on 9 pin and 7 on 25 pin.

On the other side you need a relay/or solid state relay, The PIC would be capable.

The chip on the interface card will determine the open and send procedures.

thanks for the mail i really appreciate it great deal,how do i go about the implementation of this please kindly ellusidate better

thyanks

thanks for your last mail,you actually know that am working on,and i really appreciate your concern and informations whi u have furnished me,control lines and all you have talked about really makes a lot of sense,but i need a programm on it to run on my system so as to accomplish the project,i have already finish with the constructions

kindly help
