I think it was in the late 90s when a vicious ice storm took out power lines everywhere and the whole downtown core was plunged into darkness for the better part of a month. Fortunately, out where we lived in the suburbs, the power mostly ran underground and was restored pretty quick.
But then my wife got a panicked call from a distant relative who said she couldn’t reach her daughter studying at the university and could we look in on her? So we found her and offered her the guest bedroom for as long as she needed it.
At first, it seemed to be working out? Then it began to emerge that she was some sort of evangelical Christian who was frustrated that we were not eager to convert. I sort of thought taking in a refugee was a fairly Christian thing to do, but whatever.
Eventually, she demanded I take her back to the dorm. I told her downtown is still dark and cold, but she said “I don’t care. You guys are so boring!” So I carefully drove her back around downed trees and power lines and dropped her off.
I felt pretty bad about it and we prayed she’d be ok. A couple of weeks later, the relative called again and thanked us so much for taking care of her daughter and that we went way beyond the call despite how things turned out.
I work with 32MHz microcontrollers at work and you can do plenty with them. It’s a different world from say general CPUs where speed is king. You’re often more concerned about timing reproducibility than outright clock rates. There are also considerations about power consumption, electrical noise, functioning in extreme environments, etc. that may inform your decision to go with one controller over another.
