Fill in the following table with the bytes you receive. Start by filling in the "values received" column by directly copy-pasting the bytes. Then, use the tools guide to fill in the "explanation" column.
What is the state (value) of your pin?
Info icon false title Answer 17.82: Connect a jumper between the
DP2andVSUPPLYpins. Make sure you can read the value of digital_in/D0 to be high.Connect a jumper between the
DP2andGNDpins. Make sure you can read the value of digital_in/D0 to be low.Warning NEVER CONNECT
