    How to add library function to keil library ?

    I got to create a header file, but where to place it and add it to library, and where its (Lcd.c) file will be stored? I mean what procedure I need to follow to add this header file to add to KEIL library, so that further I can include this file in my projects code.

    noise in rs-485 communication channel

    Definitely you are right,switch controls the operation of nodes,so i think this is a n issue of noise,So what should i do ?

    noise in rs-485 communication channel

    Dear all i have a problem . in my project i have 5 nodes interconnected with RS-485 channel, and all nodes have one switches when switch is pressed then controller pin goes low and master performs the operation. it was good at testing,but at validation controller gets trigger automatically...

    Difference between RS232 and RS485?

    Re: difference between rs232 and rs485 Dear all, the general difference is the extended length of communication wire in RS-485 and apart from that RS-485 can perform multi node operations which RS-232 can't. example 2 wired and four wired connection for RS-485. you can check it out...
