@web-font-path: "roboto-debian.css";
This directory code that is common to all builds regardless of PICO_PLATFORM
. It is a mix of common header files, or high level functionality built entirely using hardware_
or pico_
libraries provided by the actual target PICO_PLATFORM
`
This directory contains libraries specifically targeting the RP2040 or possible future related devices. It is selected when PICO_PLATFORM=rp2040
(the default) is specified for the build
hardware_
libraries exist for individual hardware components to provide a simple API providing a thin abstraction hiding the details of accessing the hardware registers directly.
pico_
provides higher level functionality you might generally find in say an OS kernel, as well as runtime support familiar to most C programmers.
This directory contains header files defining the RP2040 hardware. It is selected when PICO_PLATFORM=rp2040
(the default) is specified for the build
hardware_regs
contains low level hardware register #defines autogenerated from the RP2040 chip definition itself.
hardware_structs
contains C structures for accessing memory mapped registers
