}
3.2 framework do not
interrupt handler needs to contain the following 2 header file:
#include <Cyg / HAL / hal_intr.h>
#include <Cyg / HAL / drv_api.h>
4 Taglist
4.1 from the Download taglist.vim Internet
need to register an account
4.2 the Install
4.2.1 ~ / .vimrc Setting
Copy the Comment at The following to ~ / .vimrc
or less "(left double quotation marks) the latter represent comments
example: "Always Show the Tlist
" Always Show the Tlist
the let Tlist_Show_One_File. 1 =
the let Tlist_Exit_OnlyWindow. 1 =
the let Tlist_Auto_Open. 1 =
the let Tlist_WinWidth = 30
4.2.2 taglist.vim
mkdir ~ / .vim / plugin
CP taglist.vim ~ /. vim / plugin
4.2.3 the taglist shortcut
jump to the left function list window: ctrl + w key is pressed twice
to jump to the right window Source: selection function, pressing the Enter key
when the function list on the left window is closed, with the vim open the following command: ": TlistOpen"
needs to close the left window list function, may be as follows in order to close with vim: ": TlistClose"
Or use the "ctrl + w 2 key press the" Go to the left of the window, and then enter the following command: ": Q"
4.3 The Whitespace the Show
the Copy to Comment The following ~ / .vimrc
less "(left double quotes) represents the back Notes
For example: "whitespace
" whitespace
highlight whitespaceEOF ctermbg = Red guibg = Red
match whitespaceEOF / \ S \ + $ /
