@skorokithakis
so i'm guessing you can get 500 khz
actually sorry
1 usec
so probably 1 mhz
try it out, though, can't be too hard to write a for loop :P

@beikeland
main downside to Eagle is you only get one sheet for the schematic. Board size and layers limitations hasn't been an issue yet. (unless you try to do panels, but there are other tools to do so). But it does sound like its time to look at KiCad again
Chris Elsworth
@celsworth
time for scope testing I guess
Stavros Korokithakis
@skorokithakis
@celsworth do you have a logic analyzer?
Chris Elsworth
@celsworth
only a cheap ripoff.. £15 from aliexpress thing
but yes
Stavros Korokithakis
@skorokithakis
hah, 15 quid? i got mine for $7 :P
Chris Elsworth
@celsworth
it was still a lot cheaper than a Saelae ;)
Stavros Korokithakis
@skorokithakis
but yeah, i was going to offer to check out the frequency if you didn't have one
i agree
i kinda feel bad though, their logic analyzer software is so good that i want to support them
maybe my next analyzer will be a saleae
Chris Elsworth
@celsworth
likewise, but they are very expensive :/
Stavros Korokithakis
@skorokithakis
eh, it's less than $100 i think
oh, $109
not prohibitively expensive, but yeah, it's not $7
Chris Elsworth
@celsworth
well, the 4 isn't.. very good :/
Stavros Korokithakis
@skorokithakis
oh? why not?
Chris Elsworth
@celsworth
it looks quite limited in speed, very low sample rates?
the 8 is almost 10 times faster
Stavros Korokithakis
@skorokithakis
hm that's true
i'm a novice, so for what i do i only need kilosamples/sec
Chris Elsworth
@celsworth
and also you get a lot more analog ports on the 8, only 1 on the 4
Stavros Korokithakis
@skorokithakis
i think my cheapo chinese one can do 25 MS/s
yeah :/
Chris Elsworth
@celsworth
even that 25M/s is faster than the Logic 4 :(
Stavros Korokithakis
@skorokithakis
yeah exactly
so you'd be paying 12 times more for a downgrade
Chris Elsworth
@celsworth
yep, kinda silly
so if I was going to get any I think it would be the 8.. don't need the Pro
good thing really as by then you're up to $400 :)
Stavros Korokithakis
@skorokithakis
yep :package:
:P

on another note, I'm starting to dip my toe into native sdk coding a little, and every time I do I have newfound appreciation for how simple arduino core makes all this :)
Stavros Korokithakis
@skorokithakis
sounds like i should steer clear from the native sdk, huh
Chris Elsworth
@celsworth
setting a pin to do pwm, one line of easy code in arduino, and I haven't yet worked out how to do it in native sdk after 15 minutes of looking at sdk docs
Stavros Korokithakis
@skorokithakis
wow
Stavros Korokithakis
@skorokithakis
do the pullup resistors for the bare esp need to be 10k, or can i use 3.5k?
Sven Eliasson
@comino
you can
Stavros Korokithakis
@skorokithakis
will it affect anything?
Sven Eliasson
@comino
more power consumption
Stavros Korokithakis
@skorokithakis
ah, thanks
Sven Eliasson
@comino
and maybe slower flanks for the esp
(high -> low)
Stavros Korokithakis
@skorokithakis
hmm i see
that should be fine
