Message-ID: <44068C05.6020402@dontronics.com> 3-Mar-2006 Hi Don, Please find attached a PC windows based Graphics Composer application for the uLCD-MkII. Would you please post this on the uLCD-MkII page and also announce to all the user groups. This application enables a slide show type of a presentation to be composed on the uLCD-MkII which can be a mixture of text, images and animations. All of the uLCD-MkII modules come with a preloaded presentation in its internal 1Mb flash memory. The presentation was composed using this windows based application.

Message-ID: <000001c6426c$7de13450$6400a8c0@pat4> I just discovered the Micro-VGA tonight, I was actually looking for information on composite LCDs so I could display colour video from my MCU through an ezVid (www.multilabs.net). I don't really like the idea of using composite video, particularly at 188x254 (no, the numbers aren't reversed - that's for square pixels), so the micro-VGA was like a gift from heaven! I read what's on the Dontronics site and in the mailman archive so I have a pretty good grasp on the units (like why its 320x220 instead of 320x240). But one area I'm still ignorant of is hooking up to VGA LCD panels. Surplus panels aren't likely to have the nice VGA port for a standard VGA cable, so I have to figure out how to get from the baseboard to the panel (of course, I have to choose a panel first!). I may have to just use a core and do the transistors et al myself and connect with a header of some sort. The other area of ignorance is colour bits. The pinouts show color1, color2 and colourblank, 3 bits for each of RGB? I thought that 9 bits would be 512 colours, not 256? Can I use this with a panel like http://www.rtd.com/panels/lq9d031.htm that has 12 bit resolution (4 pins per colour)? Lastly, if anyone has recommendations on an LCD panel around 5.6" to 8.4" that they've used successfully, I'd love to hear about it!

The LCD panel requires extra signals like FLM, SHIFT CLOCK, LP etc. which the micro-VGA does not support. You should be able to source some very cheap 15" or 17" LCD VGA monitors fairly easily. The micro-VGA supports 256 colours, 3 bits for RED, 3 bits for GREEN and 2 bits for BLUE (8 bits in total). There is a reference design schematic available on the web page for you to include in your embedded application if you choose not to use the Base Board. You cannot use the micro-VGA with the LCD panel you've indicated in the link. If you're after a tiny (1.5") 65K colour LCD, then this might interest you http://www.dontronics.com/micro-lcd.html http://www.dontronics.com/micro-lcd_mk2.html Hope the info helps.

Unfortunately for me, I need a display between about 5.6" and 8.4" and the only actual "monitor" LCD I can find in that range is around $500 US which is too expensive for the product I have in mind. Both composite and VGA panels, on the other hand, can be had at places like www.eio.com for $50 -$75. The problem is in interfacing them to a microcontroller... Well, I'll keep looking and see if there is a small sized lcd monitor out there that doesn't cost 5 arms and two legs. -----Original Message----- From: Micro-VGA-bounces at dontronics.com [mailto:Micro-VGA-bounces at dontronics.com] On Behalf Of Atilla Sent: March 7, 2006 9:22 PM To: 'Micro-VGA Group' Subject: Re: [Micro-VGA] LCD recommendations?

The demo correctly displays "uVGA" on the monitor, but it will not respond to anything, even a simple 'U' (55h) or 'E' (45h). The only time I receive anything from it is occasionally when the power is removed or plugged in (FF, CO, or FE). I don't think the uVGA is defective because I have two of them and neither one responds. The power supply is 9v 300mA, and i've been connecting the device to COM1 using a standard DB9 Cable and Docklight software. COM1 works fine with other devices. Should the RS-232 cable be converting to TTL levels for the RS-232 uVGA, and if so, where could I find information on how to purchase or build such a thing? Any other advice or things to try would be appreciated. Thanks, Will ________________________________________________________________________ Try Juno Platinum for Free! Then, only $9.95/month!
