树莓派SDK(Software Development Kit,即软件开发工具包)提供了头文件、库、以及编程控制以RP2040为核心的设备(例如树莓派pico)所需的构建系统。 该SDK旨在提供API(Application Programming Interface,即封装好的函数),以及适用于爱好者与专业开发人员的编程环境。程序通过传统的main()函数在设备上运行。标准C/C++库支持...

is a bit simpler to set up using Pico SDK version 2.0. Before you attempt to build this project, please set up and build thepico-usb-midi-filteras described in the linked Software section of theREADME.mdfile. That section describes how to set up the SDK, and patch the TinyUSB library...
core/built-in types have been compressed by only including in the C-level type struct as many slots for C function pointers as is needed for a given type (instead of storing NULL pointers for unused slots). This resulted in a reduction of code size of many kilobytes for all ports (eg ...
