I have a project now, using Atmel's AT89C51RE2 as MCU. I've already checked each UART(UART0, UART1) worked alone in mode 1, but I need 2 uarts works simultaneously. I heard for both uarts working, each uart configuration has different baud rate, and different mode, is it correct? anyway, I tried to make uart work in mode 3, but I failed. Could you give me any advice ?? (or eg?)
thank you.
I appreciate your relpy.
but I'm not good at english. I don't understand 'they must be interrupt driven' means.
Could you please tell me more in detail?
take a look at this tutorial: www.8052.com/.../120308
In fact, there's a whole section on 8051/2 serial comms at http://www.8052.com/faqs
Hint: When is SBUF ready to take the next character...?
