配置pico-sdk开发环境-WSL+VScode

配置pico-sdk
#

使用官方脚本：

git clone https://github.com/raspberrypi/pico-setup.git sh ./pico-setup/pico_setup.sh

会自动配置pico-sdk\picotool\openocd以及环境变量这里我把SDK移动到了%HOME%/_PATH_下

export PICO_SDK_PATH=/home/cerry/_PATH_/pico/pico-sdk
export PICO_EXAMPLES_PATH=/home/cerry/_PATH_/pico/pico-examples
export PICO_EXTRAS_PATH=/home/cerry/_PATH_/pico/pico-extras
export PICO_PLAYGROUND_PATH=/home/cerry/_PATH_/pico/pico-playground
export FREERTOS_KERNEL_PATH=/home/cerry/_PATH_/pico/FreeRTOS-Kernel

这个是bash的配置,如果使用的是fish,要使用fish的配置文件 %HOME%/.config/fish/config.fish fish下可以配置为:

set -gx PICO_SDK_PATH /home/cerry/_PATH_/pico/pico-sdk
set -gx PICO_EXAMPLES_PATH /home/cerry/_PATH_/pico/pico-examples
set -gx PICO_EXTRAS_PATH /home/cerry/_PATH_/pico/pico-extras
set -gx PICO_PLAYGROUND_PATH /home/cerry/_PATH_/pico/pico-playground
set -gx FREERTOS_KERNEL_PATH /home/cerry/_PATH_/pico/FreeRTOS-Kernel

来到VScode这边,来配置环境: 安装WSL插件点击左下角打开远程端口连接到WSl

给WSl下的VScode安装插件 C/C++ CMake 可选:Raspberry Pi Pico(当然选择这个后, 环境会自动安装到%HOME%/.pico-sdk下就不需要配置这些了

测试项目
#

创建一个项目文件夹 myapp
复制 <PICO_SDK_PATH>/external/pico_sdk_import.cmake 到app下
编写CMakeLists.txt文件

cmake_minimum_required(VERSION 3.13)
include(pico_sdk_import.cmake)
project(myapp)

pico_sdk_init()

add_executable(sb "app.c")
pico_add_extra_outputs(sb)
target_link_libraries(sb pico_stdlib)

编写app.c

#include <stdio.h>
#include "pico/stdlib.h"

int main()
{
    return 0;
}

生成目标
期间弹出选择编辑器,选择 arm-none-eabi

CMake可能会报错

打开设置,搜索 Cmake:configureSettings

添加 "CMAKE_EXE_LINKER_FLAGS": "--specs=nano.specs" Cmake就不会报错了

配置FreeRtos
#

cd _PATH_/pico
git clone -b smp https://github.com/FreeRTOS/FreeRTOS-Kernel --recurse-submodules
# bash下
vim ~/.bachrc
export FREERTOS_KERNEL_PATH=/home/cerry/_PATH_/pico/FreeRTOS-Kernel
# 如果是fish
vim ~/.config/fish/config.fish 
set -gx FREERTOS_KERNEL_PATH /home/cerry/_PATH_/pico/FreeRTOS-Kernel
