RobG 1,892 Posted January 20, 2012 Share Posted January 20, 2012 Still rough and slow. Some borrowed code that needs to be improved and optimized.Here you can find cubeberg's version of T6963 library. t6963.hpg128128a.hUPDATED 1/22/2012msp430_t6963.h Reuploaded on 11/26/2014 (looks like files were corrupt during 43oh migration) msp430_t6963.c main.c fatihinanc, bluehash, larsie and 2 others 5 Quote Link to post Share on other sites
bluehash 1,581 Posted January 20, 2012 Share Posted January 20, 2012 That is so cool!. Looks fast enough for flipping numbers though. Quote Link to post Share on other sites
RobG 1,892 Posted January 22, 2012 Author Share Posted January 22, 2012 Made some additions and improvements. Still working on improving horizontal line drawing routine, which will speed up filling functions. I hope to get them to draw ~4-5 times faster. bluehash 1 Quote Link to post Share on other sites
cubeberg 540 Posted March 6, 2012 Share Posted March 6, 2012 Wow - I totally missed this library. I just wrapped up a bunch of changes on mine as well (I'll post later). I was able to implement a horizontal line function as well as an Ellipse function. I also set up local variables to hold runtime values of the #defines used in the library (there's a lot of division and multiplication happening every time you want an address calculated). I know you made a lot of speed changes as well - I'll take a look and see about combining our changes. Also - the guy who sold the LCD's on eBay has a bunch more - he's got a couple up online again, as well as another 5 or so - if anyone is interested. He said I could pick them up for $3 if I wanted more. oPossum, bluehash and RobG 3 Quote Link to post Share on other sites
fatihinanc 14 Posted March 6, 2012 Share Posted March 6, 2012 Hello, Can you help me about ks0108 library written for MSP430 ? I've searched it but i can't find any information in this forum. Thanks. Quote Link to post Share on other sites
cubeberg 540 Posted March 6, 2012 Share Posted March 6, 2012 Hello, Can you help me about ks0108 library written for MSP430 ? I've searched it but i can't find any information in this forum. Thanks. I don't think that controller is compatible with the T6963c, but you could certainly map the graphic functions once you had a good base for the KS0108 (although you might need to change some of the functions we've optimized for this controller). I'd start by searching for a MSP430 library for that controller, or look into porting a library for another MCU (such as AVR). You might also have some luck starting a new thread - see if somebody else here has already used one. Quote Link to post Share on other sites
mtlevine0 14 Posted March 12, 2012 Share Posted March 12, 2012 Hey I just got on of these powertip LCD's off Ebay. Not a whole lot of info out there on the LED backlight, how are you guys powering yours? Quote Link to post Share on other sites
cubeberg 540 Posted March 12, 2012 Share Posted March 12, 2012 I'm not powering mine currently because of power consumption. It takes 450mA @ 4.2v, but runs fine @ 5v. Here's a link to the datasheet from the manufacturer's site. You might find it helpful. mtlevine0 1 Quote Link to post Share on other sites
CptanPanic 5 Posted March 15, 2012 Share Posted March 15, 2012 What would I need to connect of these Powertips to a launchpad? Quote Link to post Share on other sites
cubeberg 540 Posted March 15, 2012 Share Posted March 15, 2012 I used an old Floppy cable, a piece of perfboard and some headers to do the primary connections. You can see my setup here. The biggest pain with this LCD was the negative voltage for the contrast which required -13v. RobG and I have worked on some voltage inverters, but I have yet to use one with my LCD. You can find more about that in this topic. Quote Link to post Share on other sites
RobG 1,892 Posted March 15, 2012 Author Share Posted March 15, 2012 You should also note that PG 128128-A requires 5V for it's logic, but it's seems to be working just fine @3.6V. Do not connect 5V to your display unless you have level shifters between LP and LCD. Quote Link to post Share on other sites
