I'm actually having the same problem - PAL TV in Australia.
Everything works, I can start the board, audio starts but the screen picture does not stop rolling.
I've tried a few things:
a) Tested by uploading other code - using the Controllers library I can send serial data back to my PC and use the HackVision as an external controller [with OSX via python scripts, was fun!]
b) Tried modifying the PAL as per http://code.google.com/p/arduino-tvout/ ... tail?id=35
( Find _PAL_LINE_STOP_VSYNC, in /Applications/Arduino.app/Contents/Resources/Java/libraries/TVout/video_properties.h - replace 7 with 2. )
c) Tried messing around with other values available on the net for PAL in the above mentioned file
- Code: Select all
//Timing settings for PAL
#define _PAL_TIME_SCANLINE 64
#define _PAL_TIME_OUTPUT_START 11
#define _PAL_LINE_FRAME 312
#define _PAL_LINE_START_VSYNC 0
#define _PAL_LINE_STOP_VSYNC 7
#define _PAL_LINE_DISPLAY 260
For the life of me, I cannot get VSYNC to lock on with this PAL TV.
I haven't tried it with another TV yet, though considering thebot's post here I'm beginning to wonder if there's a defect in the crystal / atmega I've got on the board. I've doublechecked all of the solder points and searched for burn marks anywhere but I cannot find anything wrong.
Before I go out and try and just purchase the board again I was hoping you might have any other ideas?
