MAKEFILE
make 可以在任一路径下执行，只需要加入 -C <path>
即可，即告诉make工具在 <path>
路径下执行编译。方便了在 windows 命令行环境下的执行。
PREFIX = arm-none-eabi- # The gcc compiler bin path can be either defined in make command via GCC_PATH variable (> make GCC_PATH=xxx) # either it can be added to the PATH environment variable. ifdef GCC_PATH CC = $(GCC_PATH)/$(PREFIX)gcc AS = $(GCC_PATH)/$(PREFIX)gcc -x assembler-with-cpp CP = $(GCC_PATH)/$(PREFIX)objcopy SZ = $(GCC_PATH)/$(PREFIX)size else CC = $(PREFIX)gcc AS = $(PREFIX)gcc -x assembler-with-cpp CP = $(PREFIX)objcopy SZ = $(PREFIX)size endif HEX = $(CP) -O ihex BIN = $(CP) -O binary -S
startup_stm32xxxxxx.s
是使用汇编语言写好的基本程序，当STM32
芯片上电启动的时候，会执行此处的汇编程序，从而建立 C
语言的运行环境，所以称之为启动文件。
由于编译器不一致，所以 .s
的启动文件也不能互相兼容，需要使用 CubeMX重新生成。

版权问题，当你在使用keil时，出现
error: L6050U: The code size of this image (45178 bytes) exceeds the maximum allowed for this version of the linker.
的时候，那就是 keil
没有被破解，软件本身的字节数有局限性，需要下载个MDK注册机进行破解！

Mac 平台自带的 zsh 真的极不好用，同样是 unix-like 平台，跟 kali
平台上的 zsh 体验相差甚远。
一直都是黑白配色，而且修改中断和配置的动手能力确实没有那么强。偶然适用了一下
fish ，发现在 Mac
平台使用效果挺好的，就决定进行更换。切换成黑色背景后更为舒适了，之前一直使用瞎眼的白色。

FISH SETUP
我安装了 MacPorts 包管理工具，直接用 port 命令即可安装
fish 。
1
sudo port install fish
ADD FISH TO /etc/shells
使用 which fish 可以调出 fish
的安装路径（用 port 安装的话默认路径是
/opt/local/bin/fish ），复制该路径，然后粘贴到
/etc/shells 文件末尾。
