I'm not sure I'm doing this right - - - - no - - - - I"m not answering my own question (have had to do that a few times - - - grin) but there are some great ideas in the thread - - - - but - - - - . Yes I had red of the RPi Pico. RPi is rather interesting in that you can buy quantity 1 of the board reasonably and then if you want more than 1 - - - - - well you have to buy their cables and wall wart and and and making the purchase not so reasonable! One project - - - - there have been questions over what I'm trying to do - - - sorta like this. If anyone knows what a gang saw is then you have some idea of what I'm doing. I want to have one electric motor for moving like a large mass of material forwards (and back if I wish), then there is a higher hp motor to power a whole bunch (2 m worth) of blades and then there is a third moderately sized motor that moves the gang setup up and down. The gang is turning at a fairly high rpm (7500 rpm in the prototype and 10k in the design) and moving quite quickly, 2 m in under 10 to 12 seconds. So the load on the gang is monitored so that if the load moves over say 103% of rated that the gang movement speed is slowed or if the load is under 80% that the gang movement speed is increased. So there, planning is anyway, a vfd on all three items - - - - with a ucontroller per motor (maybe I don't need to do one on each- - - - dunno) and the whole being controlled from some small system. This system may be working for as much as hours per time and multiple times per day. Overloads/heating will also be monitored. This is the kind of equipment that I don't want to have to babysit but it must work. (another project is a small animal feeder - - - weighing in and out, body temperature, control the mixing, id reading water heating, - - - may not sound to complicated but there would be at least 6 or 7 different functions that need to work is a particular sequence - - - - - ja - - - I know I'se more than a little touched - - - grin!) So I have some Arduino kind of boards here - - - - they may work but they need added cape for this and shield for that. Looked in PLCs and in some ways they are more robust - - - - but pricing - - - - ouch! It is possible to get an arduino clone for likely under $5 can w/o shipping on the web - - - - a cheap plc is $85 usd and a good one might be some $250 USD. Does that help point more as to the issues? I can find a lot of information on the SoC for the umpteen different variants of ucontrollers. Sure can't find much info for boards - - - maybe large companies can roll their own designs - - - - but I'm hoping that there is some info hidden someplace for smaller companies. I just haven't been able to find anything - - - yet! Thanks to one and all for the suggestions and assistance!!!!!!!!!!!!!!!! --- Post to this mailing list [email protected] Unsubscribe from this mailing list https://gtalug.org/mailman/listinfo/talk
