UART Live mode fix #46

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
The UART live capture on Buspirate v2go, does not work. I have tried
different versions 2.5, 3.0.

I believe that it is caused by line 174 in UART.c (current trunk - r87)

if(UART1RX()==' ')break; //escape

This line waits for input from user. 
The line should be replaced by something like:

if (U1STAbits.URXDA==1){
 if (U1RXREG == ' ') break;
}

do the checking only when data is ready in the buffer.

URAT1RX includes a blocking check for data:

http://code.google.com/p/the-bus-pirate/source/browse/trunk/source/baseIO.c#340

//get a byte from UART
unsigned char UART1RX(void){

    while(U1STAbits.URXDA == 0);
    return U1RXREG;
}

What issues are you experiencing? The forum would probably be the best place to 
discuss.
