Im doing my on the Line challenge figured out the issues with the HMI Coms,
geting readdy to write the helper functions to make the arduino PLC Server respond with the IO of the arduino.
6% memory use on a Mega!
well anyway all I have for pots are these 100 turn 10 trimmers. and the Omega 5SRTC RTC Thermal Probes.
I dont want to hack off the end, but they don't fit the 2.54mm teminal blocks
omg what do?
wago lever nuts fit nicely.
So today I figured out some more of the nuances nuisances, of the HMI. .
Im sure I knew that, but its not the type of thing you might ordinarily think about.
I was messigng with File IO and boom its 10 pm. here I can leverage the arduino to give a marginally better experience.
basic IO is operational, returns words and floats.
will mess with more complex sensors such as ultrasonic, i2c encoders, and capacitance. as simple IO operations to control.
For my next trick, Ill control a blank PLC remotely.
