ADI BF533的串口通讯调试程(已经通过测试了)

Project Name: UARTExample

Project Type:
ADSP-BF533 [X]
ADSP-BF537 [ ]
ADSP-BF561 [ ]

NOTE: This project is configured for Debug, by default. If configured for Release Mode,
a silicon anomaly may cause the example to fail with a hardware error condition after
the program has been loaded. Bit 5 (IVHW) will be set in the Interrupt Latch (ILAT) register
Select "Register->Core->Interrupt Controller" to view ILAT. To avoid this error, go to
"Settings->Preferences" and remove the check next to "run to main after load". Reset the
processor and rebuild.

Hardware Used:
Uart

System Services Components Used:
DMA Manager [X] Deferred Callback Manager [X]
Interrupt Manager [X] Timer Module [ ]
Power Management Module [X] Flag Module [ ]
External Bus Interface Unit Module [X] Port Module [ ]

Example Overview:
The example called UARTExample demonstrates how to use the UART device driver
in talkthrough or echo mode.

Characters typed in at the computer are echoed back using the chained dataflow
method. Callbacks can be made "live" or deferred by defining the macro
USE_DEFERRED_CALLBACKS as shown in the source file.

File Structure:

"./UARTExample.dpj" - Main project file
"./UARTExample.c" - Main source file
"./ezkitutilities.c" - EZ-Kit utilities source file for Blackfin processors
"./ezkitutilities.h" - EZ-Kit utilities include file for Blackfin processors

System Configuration:
Jumpers:Remove jumper P5 near the RS-232 port.

External connections:
Connect a terminal up to UART port on EZKit. Hyperterminal may be
used to send and receive characters to and from the EZ-Kit. Set the
baud rate to 57600, 8 data bits, no parity, 1 stop bit and no flow control.

Getting Started:

1)Load Project file "UARTExample.dpj"
2)Build Project by selecting "Project->Rebuild Project".
3)Start Hyperterminal, and in VDSP, select "Debug->Run".
4)Type characters and see that as each character is typed it is echoed back to the
terminal. For each character typed, a LED lights up, in a cycling fashion.
5)When finished, select "Debug->Halt" to stop the program.
