Interesting post Jan.

Have you made any timing tests on these functions?

I used to do timing analysis on computers and OS, so I am always interested in the time delays incurred when an interrupt occurs.

I have the SCPI lib integrated. First test is the standard *IDN? (who are you) command:

Great project!

I use the same strategy with UART on the pico too, i.e. check to see if there is anything there, and then read one byte at a time.

I bought some relays from Farnell recently for a project, and made the mistake of not checking the size, since they visually looked like a larger standard size.. instead they are tiny! These are Axicom models IM06 and IM03.

They kind-of fit standard perfboard (they won't fit flush on the board, the spacing is slightly different):
