Topic: vga! (preview)

i made a basic r2r ladder - the levels are right but theres still a little kernel tweaking to get proper vga signals out

That's cool, resolution max is the same as the S-video output ?

according to the datasheet
"Up to VGA (640x480) resolution at 60Hz LCD panel support"
considering it has to do this on-chip, thats not too bad

Sweet.. higher resolution Chumby Goodness on a monitor wink

Re: vga! (preview)

Do you have a fbset settings yet?  Is that a special protoboard?

Note the flash resolution (which can't squeeze out NTSC bandwidth) is 720x480.  It is interlaced, but it should work on a monitor - I wonder if there is a dual-output setting.

Re: vga! (preview)

Sadly, the on-chip LCD interface can only output to one device at a time.  So you'll get VGA, LCD, or NTSC/PAL, and only one at a time.

You might be able to bit-bang something to get multiple devices, but that's going to be a challenge. smile

Ladyada, any chance of you putting that nifty protoboard of yours there into production? I'd take a couple, for sure.

Re: vga! (preview)

Me too, i want that shield.
Did anyone have a link to a touchscreen LCD for the hacker board ?

Re: vga! (preview)

we're revising the PCB to match the 'release candidate' Chumby which is currently being designed - as soon as its ready we'll post - promise!

Re: vga! (preview)

Will that fit the current beta boards as well?

Re: vga! (preview)

it will work with both. we're doing one more test PCB run

Re: vga! (preview)

2ladyada. Can you show schematic of this shield? Thank you.

Sienna/brianez, You may want to send ladyada an e-mail via forum, as this thread is almost 2 years old :x

Sienna, welcome to the forums! We do ask though, that you not make a habit of reviving old threads yikes
