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,
Can hardware flow control be used to ensure that one device doesn't transmit while the processor is listening to the other...?
But two UARTs would still be better
... why not just add an external UART?!
If you're short of pins, UARTs are available with I2C and SPI connections...
Why not choose a device with two UARTS.
Job jobbed.
