Limitations of UART (G2553)

Hello there.

 

For a project I am making, the Launchpad board must be able to communicate with my computer. Mostly the dataflow will be from the microcontroller to my computer, but I may introduce communication from the computer to the Launchpad sometime in the future. I am wondering a couple things at the moment (and may use this thread to ask further questions if I have any):

 

1. If I do not plan to have the computer send data to the microcontroller, can I have another G2553 send commands to the Launchpad using this line? (TXD to computer, RXD to another G2553)

 

2. If I plan to do the above, would it be possible to have the computer also communicate with the Launchpad on the RXD line as well as the other G2553 (I imagine I would use identifier bits when sending data packets to differentiate between the two sources). IE: TXD to Launchpad, RXD to another G2553 as well as the computer.

 

I am trying to do this so I can use the two I2C pins for ADC instead. I've never done I2C or communication between two microcontrollers before so any info (other protocols/methods, etc) you think would be useful can also be included.

 

Thanks.
