Research direction

Start by locating how the examples configure the PICO_STDIO_UART and PICO_STDIO_USB CMake options, then compare that configuration with the examples that need visible output. The issue does not name files or tests, and completion depends on deciding between a USB default and a clearer user choice.

Description

enhancement

Some of the examples only really "work" if you can see the output. But by default we enabled UART which means you have to own a USB adapter.

Maybe we should default to using USB, or have some clearer explicit way for the user to specify their choice? I have a load of aliases to make the switch for me

alias cmaked="cmake -DCMAKE_BUILD_TYPE=Debug"
alias cmakeu="cmake -DPICO_STDIO_UART=0 -DPICO_STDIO_USB=1"
alias cmakedu="cmaked -DPICO_STDIO_UART=0 -DPICO_STDIO_USB=1"
alias cmaken="cmake -G Ninja"
alias cmakedn="cmaken -DCMAKE_BUILD_TYPE=Debug"
alias cmakeun="cmaken -DPICO_STDIO_UART=0 -DPICO_STDIO_USB=1"
alias cmakedun="cmakedn -DPICO_STDIO_UART=0 -DPICO_STDIO_USB=1"
