Beige 1 Posted September 27, 2010 Share Posted September 27, 2010 Ok, found something to do with the Value Line chips, a Persistence Of Vision display. Nothing quite like wildly swinging electronics in front of a camera on a long exposure Oh, and excuse the piezo, was a separate experiment... Code and big pics can be found at http://www.beigematchbox.co.uk/blog/?p=1518 bluehash 1 Quote Link to post Share on other sites
jsolarski 94 Posted September 27, 2010 Share Posted September 27, 2010 interesting way to code fore the POV display, I like it!! Quote Link to post Share on other sites

gatesphere 45 Posted September 27, 2010 Share Posted September 27, 2010 You are SUCH a win. Nice project! Quote Link to post Share on other sites
GeekDoc 226 Posted September 27, 2010 Share Posted September 27, 2010 Looking at the code, the LEDs are connected to P1.0-P1.6, correct? Also, why the transistors in your circuit? Do the LEDs draw too much current for the MSP430 to handle? Thanks for the code! -Doc Quote Link to post Share on other sites
Beige 1 Posted September 27, 2010 Author Share Posted September 27, 2010 LEDs are connected to P1.0 - P1.7, P1.7 doesn't actually light up as the font is 5x7. And if you hook the LEDs up with a 4k7 each the MSP can handle it ok, total current with all LEDs on is somewhere around 2mA for all 8, however I've used transistors so I can run them at a higher current, is this case 80mA for the set.

NJC 17 Posted October 4, 2010 Share Posted October 4, 2010 Got to represent... Even is I do only have, err, 3 posts? *Like* Definitely an awesome touch with the display. (I wish I there was an option to thumbs up, or like, anything on the internet, lol) NJC Quote Link to post Share on other sites
