I got an Video Experimenter kit recently , when I tested it (using the library example: DemoPAL) I have no text or drawings on the screen, if I move the switch to Output Select then I get the text and images but they move from left to right, could you please help me? I’m using a 7″ LCD Screen ( http://es.aliexpress.com/store/product/Pcduino-raspberry-cubieboard-7-digital-lcd-screen-display-hdmi-vga-2av/636052_1739710084.html )July 21, 2015 at 3:51 pm #2306
Are you sure that the camera and TV use PAL? Have you tried the NTSC sketch?
The switch is called “OUTPUT SELECT” and the values are “SYNC ONLY” and “OVERLAY”. Which position is the OUTPUT SELECT switch in?July 21, 2015 at 6:23 pm #2307
camera and Monitor are using PAL system.
Switch “OUTPUT SELECT” :
if I set it as “Overlay” I only see the image from the camera, I don´t see the text or graphicals from the example.
if I set it as “SYNC ONLY” I can see the text and graphics (white on black background) but moving from left to right.
I try using NTSC example but I can see nothing, I used another monitor and the efect is the same, I tried using another Arduino uno and always the same.
I review all components, re-check the solders so I do not what to try nowJuly 21, 2015 at 6:54 pm #2309
I change the camera to a NTSC and now, when switch OUTPUT SELECT to Overlay, now I can see the image from the camera and the text and graphicals from the NTSC example, but the overlay text and graphicals move from left to right very fast.July 21, 2015 at 7:08 pm #2311
Hmm. It may not work with your camera. Some video sources have poor timing.
Try adjusting the small potentiometer with a screwdriver. That may help.July 22, 2015 at 11:21 pm #2312
I tried adjusting the small potentiometer but nothing changed.
You said that is my camera “poor timing”, but I used two different cameras, so could you please tell me what camera is required for this board?July 23, 2015 at 12:15 am #2313
Do you have the SYNC SELECT jumper in the correct position? It should be on the right side “V INPUT”. These settings are described on the product page:
You can send pictures of the top and bottom of the board to email@example.com and I will look at your soldering.July 30, 2015 at 4:48 pm #2314
The SYNC SELECT jumper is in the position V INPUT.
