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.
Ya that sure is an investment but I wanted to get that product ready.
It has to be pointed out that you're contradicting yourself there. You have to decide what the goal is going to be: getting the product ready, or learning stuff on your own free time. The approach to steps like picking a controller has to be different in each case.
