Bader 7 Posted October 16 (edited) Hello Just got a 6502 A in the mail which I understand runs at 2MHz. I don't have any of those crystal oscillators, but I do have a 4MHz. Can I split the signal using logic gates? At the top of my head perhaps an XOR gate and a D-latch set/reset latch should do it? But the details are not the point, the question is, is it viable or would it not be exact enough? Thanks Edited October 16 by Bader Quote Share this post Link to post Share on other sites
StephenHorn 206 Posted October 16 I don't have time to find the exact location of his solution, but didn't Ben Eater do some kind of clock division for his homebrew VGA circuit? Quote Share this post Link to post Share on other sites
Bader 7 Posted October 16 oh I'll have a look, thanks Quote Share this post Link to post Share on other sites
EMwhite 32 Posted October 16 There is also this: He is no Ben Eater (not quite as organized, rehearsed, etc.) but based on his clock starting point, he appears to have based his design on Ben's original clock. I've got clock dividers in my modular synthesizer that work in very much the same manner. The shape of the signal (that the presenter struggles with) ultimately causes issues with the ICs dependent on clock but I think below a given # of single digit Mhz. you are probably ok and will need to try it. 1 Quote Share this post Link to post Share on other sites
Bader 7 Posted October 16 Been playing around in Logisim. To halve the frequency, don't I really just need a D-latch with the invertered Q going to the enable (or is it called input) pin? Like I've done in the picture? I don't really need to split the signal, just remove half the ticks. 1 Quote Share this post Link to post Share on other sites
StephenHorn 206 Posted October 16 Seems like that would work, sure. Quote Share this post Link to post Share on other sites
