Hi..


I want to display any color on PC LCD monitor using MSP430 controller.

For that i made one shield on MSP430 to connect with LCD monitor VGA port.

In VGA cable connection:

PIN No. 1,2,3 ---> 0 to 0.7 V (for RED,GREEN,BLUE signal line)

PIN No. 13,14 ---->13---H_SYNC ------> 0 or 3.3V (from MSP430 as per Logic)
14---V_SYNC ------> 0 or 3.3V (from MSP430 as per Logic)

PIN No 9 -------> 5V (VCC)

PIN No. 5,6,7,8,10-----> GND

And also generated code for 640X480 resolution which send 60 frame per second (@ 60 Hz)

but not getting any color or nothing on a LCD monitor screen :(
(monitor goes in power save mode)

Please let me know if you have any suggestion


Thanks
 

Are you managing a 25MHz dot clock? Without seeing your code, it's hard to advise. The schematic would help too.

Greetings,
First post your code.
second are you sure you want to use msp430 for this project? Because I am using it(msp430g2553) with 6610(132x132) lcd and i must tell you that there is nothing like fps(not even 1FPS, you can see colors updating previous screen color) even on such small display..

Have a nice day.. :)
 

Hi tushki7

Sorry for the late response..

Actually i want to use stellaris launchpad but still it is not arrived i am trying to implement basic level using MSP430G2553.

And now i get the color on my LCD monitor with resolution 960X720 @51Hz or 800X600 @60Hz using MSP430G2553 but still not reliable. when i tried to display two color at a time it seem like color going upper side it mean not a stable image(with two color).

Thanks :)

Hii FoxyRick

i am using 16MHz internal clock and got color on LCD monitor and trying to get more colors on LCD at a time.

Thank u :)
 

Greetings,
Can you post your code here?
Thank you!!
 

You should have better success with the stellaris - I'm waiting for some from TI myself. Annoyingly, my usual distributor has had hundreds in stock for a week now... and we are still waiting.
 

It looks like we all are waiting for same stellaris .. my estimated shipping date is 12 nov.. so late!!
