I am completely new working with microcontrollers, I have to us one for solving a problem. I would like some advice about what kind of source should I check for commands for retrasnmitting with the AT89C5115 and at the same time put an OUTPUT HIGH as a control signal to enable transmission in another component.

 

Hi.

I think you need to explain a little bit more about your project.

What are you transmitting?

How will you transmit?

The better the explanation, the better answers...

 

Thank you!
I am recieving a packet of bytes in UART, I need to retransmit it in UART and write HIGH in an output. This because I am using a max489 to covert to rs485, since I need to enable and disable the driver of the max489 and the device I am controlling doesn't have control I am using the at89c115 for this purpose.
