I have a problem with interfacing two serial port with 8051 microcontroller. I have to use bar code reader and RF reciver and transmitter which both of them interfaced serially. I am thinking to add an ic to controller these to serial ports, but I don't know which type of IC I should used!! could any one help me, please?
Thanks,
Unfortunelty, 8051 with one serial port is available only in out college.
I want another solution, please? if i can add some hard ware (IC) between two inputs that control them.
Unfortunelty, 8051 with one serial port is available only in out college can't you but a $5 chip yourself?
if not then answer is it at all possiblethe bar code reader and RF reciver send data at the same time? I think it is. if yes wjhat are the baudrates?
Erik
actually they do not send data at the same time on my projet!!
What do you mean about $5 chip?
Have you actually checked how much it would cost to buy an 8051-derivative with two UARTs...?
Thank you for your acceptting my request^_^
I will saearch about it
