Help - Data transfer from bf533 to PC using UART - meiya zha gan - Aug 28 5:00:00 2005
Hi,
just i'm in finishing stage of my algorithm. Now my results are stored in memory(internal or
sdram)of BF533. i want to transfer this result to PC and display it there in hyperterminal
window using UART. Analog devices gave some example code but it has Tx , Rx option and autobaud
(lengthy .asm code). i want the simple example "C" code which is transfering data
from BF533 to PC using UART. Can you help me? if you can't pls give your suggesstions.
Thanks & Regards,
Meiyazhagan.

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 which: 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
dennis
calculate your divisor which the formula
