Recive Multiple Data from the same UART

Postby Vladimir Dvorkin » Fri Jan 13, 2012 1:50 pm

Hello,

I am using dsPic 30F4011 microcontroller.
I am commuincating with the dsPIC using Xbee Pro series 1 modules, and using Simulink's Real Time Workshop.

I am trying to send multiple data from my RTW model (see attachment) using mux function and sending threw Packet output.
I can't split the recieved data vector using demux, since the UART Rx Block produce 1 output uint 8 signal, and matlab wont let me compile my program!

How can I recieve multiple data from the same UART port? (e.g. turn on LED with PORTB0, and conrol PWM)

Thanks

Vladimir

Vladimir,
You want to parse incoming data (UART Rx). I did similar for Tx. See the post "Rx Interrupt buffer size" linked here: http://www.kerhuel.eu/forum/viewtopic.php?f=6&t=143&p=453&hilit=parse+uart#p453.

You might get some ideas that will work for you.
Regards,
John
