yeah, reading them is fine, I want to set them.  I can use the uroms, they do set from a url.  I have other plans for them, but if the ttl inputs can't be set, which does make sense, then the uroms will have to share duties

well, you're up late  :) the guide shows how to set the outputs that way, so I gave it a try.   if the outputs can be set by url, are the inputs somehow impossible, or is this another security measure? I already set some of the inputs from a labjack, but that is way separate from this...

I would like to go there, completely off the grid.  this is just for a monster swamp cooler, and it only needs to run during the day when it is sunny.  the rest of the facility has A/C, which already sends the billing rate above the level that Edison deems appropriate for us.  the cooler has a...

the MCP23017s are i2c digital inputs, 16 on a chip, bidirectional, and addressing support for 8 of them on the bus.  I have three of them so far.   but when this started, I didn't know about them, or that it would be so easy to extend the number of digital inputs for the webcontrol.  I already...

I haven't fielded the actual sensors yet, still waiting on the spool of cable.  so I still don't know what the real typical voltages will be.  and it does already have a divider & trimpot on the sensor board.   after all that is in place and adjusted, I'll report back what the best scale seems...

  Thanks for this example Ross, and the pictures.  My battery room also happens to be where the wc8 is. 24v tho, so only semi-serious  :unsure:     but I have three PCs living there, one of them dedicated to acquiring the data from the wc8, and also from an OS wmr100 weather station.  so plenty...

yes, I understand that, I had to install a software serial port for a medical client.  but what kind of serial devices, or webcontrol peripheral, do you expect wc32 users to want to connect to from their pc, and why do it thru this port?  can you give some examples?  a serial hardware modem?  a...

or is this where some user serial device(s) could be connected to the wc8, and then communicated with from a pc, over the lan with the emulated port?

ok, this is the part I was after.  but exactly what webcontrol peripheral(s) can I read and write data to?  something on the i2c bus?

did look at the datasheet, seems that you can typically have two on the bus, but to have any more than that requires ordering the alternate addresses, as they come hardwired  The device code is followed by three address bits (A2, A1, A0) which are programmed as follows: • The choice of A2 and...

can you explain a little more how these two serial ports might be used with the wc32, once the emulator & bridge are installed and a connection can be made?

ok.  I already do use the uroms thru urls for that, but as I said, it is limited.  and the plc code becomes more complex I'll necro the serial port thread to hear about that

I have an interest, it could be useful for making some multitone audible alarms, among other things.  but I am currently too busy to play with one. I would still watch if you wanted to demo one

I see the wc32 serial port thread, but it rather promptly changes into a wifi discussion, without enough info about using the port.  I see there are actually two, but I'm not clear on what can be done with them.  After I install the emulator and bridge, and can connect to the port, then what?

sure, of course it is behind my firewall.  and since it is, I'm not really needing any additional unnecessary embedded security measures, like making it impossible to change things remotely, from within my secure lan  :mellow:   but, I'll live with it and won't make a feature request.  I have my...
