Dear All,
 
I would like to know what the DSP processor does
1. during Fetch, Decode and Execute.
2. Assume high & low priorty interrupts are enabled. Low priorty interrupt has occured, processor is in the service routine of 50 instructions, during this time if high priorty interrupt occurs what will happen
3. Assume high & low priorty interrupts are enabled. High priorty interrupt has occured, processor is in the service routine of 50 instructions, during this time if low priorty interrupt occurs what will happen

Hi

look into the \VisualDSP 4.0\Blackfin\EZ-KITs\ADSP-BF561\Examples\UART
RS-232 HyperTerminal session\Core A\
direktory of your VisualDSP instalation.

there is the UART_Library.c  its the asm code portet to c

you need the funktions:
UART_init, UART_waitForTransferCompletion, UART_putc, UART_puts,

Calculate your divisor whith:  BAUD RATE = SCLK/(16 x Divisor)

so eg for SCLK 118.8 Mhz and a wonted baud rate of 115200 you need
a divisor of 64

UART_init(64);
UART_puts("helo world");

tada

and dont forget that you need a 1:1 cable not a crossed nullmodem one
beetween the bord and the pc

Dear Group,
 
If any one have any example code of UART for Blackfin 533 which is written in C language.
Please share with me. In Visual DSP++ it is there but it is Assembly code.
 
Thanks
