Jan 25 16:47:49 <set_> Frocks of beagles. What ever happened to the girl who was designing clothes to articulate feelings while moving within the garments? There was one that had haptic sensors that could sense differences in movement and "feelings."
Jan 25 16:49:06 <set_> Like blood pressure, etc.
Jan 25 16:49:55 * set_ says the Diva within craves more in life.
Jan 25 16:50:04 <set_> Me namely.
Jan 25 16:50:08 <set_> Anyway, all for now.
Jan 25 16:52:41 <set_> Hey... @zmatt: If you ever get around to understanding my ill-fate, can you reply one day to these ideas?
Jan 25 16:54:38 <set_> My LOW is too high. My HIGH is just right. My circuitry gives a high LOW and a good HIGH but the Rising Edge seems off at 2.67v which is not enough to warrant driver control via the GPIO from the BY-AI.
Jan 25 16:54:58 <set_> ...
Jan 25 16:56:30 <set_> I am doing my best to try to not break the machine but my attacks are way off. I need something other than the chips I current have now. I am using a ULN2003A which is supposed to handle some type of TTL and some type of CMOS if given that data which will output that data.
Jan 25 16:57:22 <set_> Anyway, if any of it makes sense, please reply. I would like your feedback.
Jan 25 17:46:43 <ds2> eh?
Jan 25 18:02:24 <set_> Aw...
Jan 25 18:02:27 <set_> Okay.
Jan 25 18:02:45 <set_> So, I need my low to under 0.5v for the GPIO but the HIGH is okay now.
Jan 25 18:03:00 <set_> My low is 0.67v and it is too high.
Jan 25 18:03:53 <set_> BY-AI output of a GPIO is what I am discussing but there are more logic down stream that are giving me a hard time.
Jan 25 18:04:40 <set_> The GPIO from the BY-AI goes to a level shifter to supply CMOS to TTL data (GPIO) to a ULN2003A and then to a motor driver.
Jan 25 18:05:55 <set_> I tested every step. The current LOW is too high for the ON/OFF of the circuitry of the motor driver.
Jan 25 18:06:46 <set_> Is there a "cure all" that can remove voltage without a trimpot?
Jan 25 18:09:29 <set_> I need to remove the LOW voltage of the LOW state to a value of 0.0v to 0.5v. I have 0.65v now on my LOW end for now.
Jan 25 18:14:15 <set_> Everything else, value wise, seems normal and this is the oddity only. I am about ~0.15v to ~0.649v away from making this driver work and the ~0.15v to ~0.649v is where my LOW needs to be less than 0.65v to make it work.
Jan 25 18:14:36 <set_> I need a super micro-reducer.
Jan 25 18:17:00 <set_> But...those are my calculations and not a real-world working order for now. So, without anymore mathematics involved, I need to drop my voltage on the LOW portion of the GPIO to 0.0v to 0.5v in reality and keep my HIGH portion as it is now, i.e. 4.65v.
Jan 25 18:17:29 <set_> Education me!
Jan 25 18:19:17 <set_> See, if I never went to school, I would have never found out about anything. I could just be uninformed (like now) but worse.
Jan 25 18:21:53 <set_> So, low drop-out, HIGH side current limiter?
Jan 25 18:22:17 <set_> But...yea. But.
Jan 25 18:26:22 <set_> and of course they do not have PDIP. Why would you want PDIP if you can manage altering current?
Jan 25 18:27:14 <set_> Okay. I should break for noodles and sauce. I am in a snowball uphill.
Jan 25 21:38:25 <set_> More parts to the rescue!
Jan 26 02:46:35 <ds2> wonder if a schmitts trigger will do or a 74HCxx buffer
Jan 26 02:56:26 <ds2> or maybe a pull down resistor
