Jul 28 09:57:09 <beewoolie-afk> prpplague: hey man.  I have some sad news.
Jul 28 09:57:16 <beewoolie-afk> prpplague: (not too sad, really)
Jul 28 09:57:52 <prpplague> beewoolie-afk: ?
Jul 28 09:57:55 <prpplague> beewoolie-afk: do tell?
Jul 28 09:57:59 <beewoolie-afk> prpplague: :-)
Jul 28 09:58:19 <beewoolie-afk> prpplague: I just dicovered that the usleep function in APEX for the LH79520 is *completely* wrong.
Jul 28 09:58:48 <prpplague> beewoolie-afk: doing some lh79520 testing?
Jul 28 09:59:07 <prpplague> beewoolie-afk: seems like i fixed that when i was working on apex earlier
Jul 28 09:59:19 <beewoolie-afk> I'm writing a SMC91x driver so that we can tftp from the lpd79520 and the lpd7a40x's.
Jul 28 09:59:29 <beewoolie-afk> Did you forget to tell me?
Jul 28 10:00:13 <beewoolie-afk> The thing I just realized is that the counter counts down.  I had written the routine with the assumption that the counter counts up.  Big oops.
Jul 28 10:00:40 <prpplague> beewoolie-afk: yea, probably forgot, i had some patches ready for you, but never sent them
Jul 28 10:00:52 <beewoolie-afk> prpplague: BTW, isn't there a clever way to divide by 5 without using division?
Jul 28 10:01:15 * beewoolie-afk is furious for about a picosecond.
Jul 28 10:01:48 <prpplague> beewoolie-afk: seems like their is, but arm asm isn't my strong point
Jul 28 10:02:09 <beewoolie-afk> It's not an arm thing, but a binary math trick.
Jul 28 10:02:19 <ByronT-Desktop> flip the bits?
Jul 28 10:02:41 <prpplague> beewoolie-afk: oh i thought you ment with arm syntax
Jul 28 10:05:22 <beewoolie-afk> It's something like shift and subtract.  Basically, I think it is a way to perform the same function as the divide instruction, but knowning the divisor makes it simpler.
Jul 28 10:05:56 <ByronT-Desktop> I was just thinking that if you find the most significant bit and then start flipping, you should get 1/2
Jul 28 10:06:03 <ByronT-Desktop> 010 / 2 = 001
Jul 28 10:06:15 <beewoolie-afk> right.
Jul 28 10:06:32 <beewoolie-afk>  /2 ->  (>>1)
Jul 28 10:06:54 <beewoolie-afk> If I remember is right, it's long division with binary math.
Jul 28 10:08:14 <ByronT-Desktop> but binary math was a looooooooong time ago for me
Jul 28 10:08:35 <beewoolie-afk> So was reading, but I use it every day.  :-)
Jul 28 10:10:53 <ByronT-Desktop> aha!  I finally got my FrankenSlug's FrankenStein UBE serial cable working!
Jul 28 10:10:54 <ByronT-Desktop> woot
Jul 28 10:20:05 <beewoolie-afk> Nice work.
Jul 28 10:32:43 <ByronT-Desktop> I have three more cables to-do...
