SPI acceptable slew rate
I have a poor-mans level translator (the resistors are swapped to 2k) and stuck a scope on it. The slew isn't great and my question is what is acceptable? I'm not exactly sure how it works but imagine having a slew shifts the point at which the clock is recognised and a data shift begins, so if the data line has a worse slew then the value may not get picked up?
I'll change the approach on my next prototype revision but hoping to make this one work for demonstration purposes.
