MSP430G2 UART in multiprocessor mode

Hi Viking,

 We are still working on the documentation, the code that Michael provided, is just a small piece of an App Note (LIN) that we are currently working on.

So if you want to try this, please call this function to initialize your UART

UART_Init(USCIA_0);

and then please review the User's Guide (SLAU144) - 15.3.4 Automatic Baud Rate Detection

The bytes received after the break/synch sequence is sent (message) should trigger the function call Rx_ISR in the USCI0RX_ISR.

__interrupt void USCI0RX_ISR(void)
{
  uint8_t sync_rx_byte;

   if (SBF_Received)
   {
	   sync_rx_byte = UART_Rx(USCIA_0);
	   // Receive Message
	   Rx_ISR(USCIA_0,sync_rx_byte);
   }
   else
   {
	   SBF_Received = true;
   
	   // Clear BF flag and disable Interrupt
	   Clear_UART_BF_Flag(USCIA_0);
	   Disable_UART_BF_RX_DormantMode(USCIA_0);
   }
}

Hopefully this helps.

  Best regards,

David,
Thanks a lot for addressing this. We are impressed. Got he Auto Baud Rate Detection working. (it does appear to be some built-in support for this that I am not using fully, so your full documentation will be helpful).

However, still not able to use the multiprocessor support, mostly because of very little information. I look much forward to the new documentation.

Please make sure to update me as soon as this is available. And again, Code is King; need for much documentation other than a working code example.

Regards, Erik
