Help with VGA and an ADC0831 I am using the demo board REV F

floodhound

I have a couple of question about the propeller.
·
1)····· I have tried to plug in a monitor to my DEMO board and running VGA objects, I get nothing. Can some one help me or is my old monitor to big?
2)····· I wanted to use an ADC0831 A-D is there any code out there I can use?



Thanks

1) What VGA drivers have you tried? What kind of monitor do you have and what resolutions does it support?

2) Have you looked in the Propeller Object Exchange? There's an ADC0834 object you could modify to use with the ADC0831 since the latter is so similar to the ADC0834.

Ok I was a bit off and now I am on track.

Solution - I was able to get the VGA to work; I needed to make sure to set the monitor to 800 X 600 using windows before I plug it in to the propeller. Now it is working great.


Thanks for the help

The VGA Hires Text Demo driver has an 800 x 600 setting, but that's not the default. Have a look at the comments at the beginning. There are 3 sets of constants at the beginning, one for 800 x 600. Take out the comment brackets around this block of constants and make sure the other two are commented out, then compile the demo. It should work.
