the input on these drives an IR LED on a photo triac, already optically isolated

hmm. the arms in the first photo appear to be out of position – “off by one”

News - Happy Free Day | about a year ago

good grief, what a bunch of rude jerks. especially the HORDES of new users. did any of you have to pay to participate in free day? no. so stop being asses if you didn’t get all of a $100 allotment, or even anything at all.
everybody knows from the start that it’s going to be hellish to get a page to load during the entire event. if SF servers were capable of lightning fast responses for everyone, the entire event would be over in a few hundred milliseconds, and we’d still have an angry horde of jerks. $150,000 / $10 per question == 15000. with $100 per person, that’s 1500 people at perfect answers.
either it goes fast, or it goes slow. but do the math and stop whining. spreading $150K around will get thin quickly.
appreciate SF for what they give back, and what they do for the community. it’s a hell of a lot more than what -you- are doing.

hey HM,
well i’m not familiar w/ the pic32 but my immediate reaction is to attach a serial to parallel chip in there if i already have this module in hand. i use 8bit data access on this module, 10 bits for address. so you’d want a total of 18 bits for those two busses, and you’ll need four more pins to manage. if the wiz830mj is the only device on the bus, you can hardwire /CS to ground and rely on signalling with /RD and /WR. the last two pins you must use are /RESET and /LINK. /RESET is obvious, and /LINK indicator is important since you don’t want to send packets when there’s no network connectivity (it can hork up the w5300 on bootup).
do you have SPI or i2c on the pic32? you can use the mcp23s17(spi) or mcp23o17(i2c) io expander. that’ll give you 16 bits of bidirectional flow per chip. see the datasheet for info on that critter
digikey has plenty of different i/o expanders to choose from.
if you want native serial access, the wiz812 may suit you better. it comes with the w5100 chip rather than the w5300 chip, so it gives you four sockets rather than 8.

let me know if you still need code/support on using this, i have a fairly well developed codebase for this guy

FirefighterBlu3: is there an actual datasheet for this or just a marketing splash page?
nevermind. apparently i only got the first two pages of the datasheet the first time it downloaded.

yes, please. a stippled shaded background is usually better. just dark enough to show contrast with white objects :)

Product PGM-07834 | about 2 years ago

penguin certified? i.e. works great in linux using USB connection?
