I am doing a project and in that project i am using one MAX232 but with multiple Microcontrollers i know that i cannot use RS-232 to multiple Microcontrollers but i am using MAX232 to convert the RS-232's 23V to TTL (5V) and so as the RS232 is converted to TTL so i think that it will work for multiple Microcontrollers (am i right?) well this is my stratigy ...
but my main task is that i want to send a HexaDecimal no through the Serial port so that the approriate Microcontroller will responce .... so i have coded some code but as i cant see the value came into SBUF in keil so could any one help me ?
Well Thankyou sir for your sharing of knowledge and i would like to thank you all of members who shared their knowledge well i have got little bit idea of how i can use Address bit and how to configure them but if i feel any difficulty then i would probabally create a new thread .... ;-)
