Note: (1) Open the "Exe\guisimulationdebug.exe" under the project catalog to see the effect. (2) After reading the tutorial 000~005 will basically use Emwin to do the project, other chapters can be consulted when necessary. Emwin Timer is a software timer, it takes the value of the Os_timems variable as a timing benchmark, and os_timems through a hardware timer per 1ms interrupt plus 1, in the Emwin internal program constantly query Os_timems changes
