Hi guys, Here is the situation I've 89c51 microcontroller board which I want to connect with PC as well as GSM but as everybody knows it(8051) has only one UART so one solution is try using 87xx or 83xx series of controller but that means I'll have to change my programmer. So what I'm thinking is I'll use simple mux/demux for Tx/Rx of 8051. I want to know will it be o.k.? Can simple AND or OR gates can handle data rate of 9600bps?
Thank you very much in advance.
Thank you very much Per Westermark. That worked well when I put while(1){} anyway what is this start up code - keil used to ask every time do you want to copy and stuff but I don't understand it much. Can you please guide me where can I read about it or so I would like to gain more knowledge
Please guys don't go for that success tag in future if somebody want to do so. I guess this method is failure anyway will let you know for sure in a day or two When I put incremental characters i.e. a,b,c,d,e,.... in transmission i got at receiver is random characters still I'll try for a day or two
"Can you please guide me where can I read about it"
It should come as no surprise to find that you can read all about it in the compiler's Manual!
