In order to make use of this facility the following
instructions should be followed:
1. The ADV7194EB has to be connected over the 25pin
pixel port to a signal generator supplying valid
CCIR601 data.
Jumper J8 has to be set to J8B.
2. The disks supplied with the ADV7194EB contain a
file called 94dem.asm.
Double click on ASM51.exe and name the path and
filename of the .asm file. A message should come up
which reads:
ASSEMBLY COMPLETE, 0 ERRORS FOUND
3. Connect the 5pin connector to P3 (N.C. on pin 5).
Insert jumper J18.
Power-up the board.
This special cable can be provided or requested from
Analog Devices.
4. Double click on DEBUG812.exe. Under
SESSION, click on DEMO.SES. In the
CONFIGURATION window, click on FILES and
load the compiled .lst and .hex files for 94dem.asm,
that is 94dem.lst and 94dem.hex.
5. Press the RESET button on the board. Click on
RESET in the CONFIGURATION window. The data
will be uploaded and the
status bar should read: Data uploaded successfully.
6. Click on the PROG icon in the ADuC812
Debugger. The status bar should read: Data uploaded
successfully.
7. Click on the RUN icon (next to PROG).
8. Load the ADV7194 Evaluation Software.
Cancel the message which shows up in the main
