Embodiment Construction
[0042] The technical solution of the present invention will be described in more detail below with reference to the drawings and embodiments.
[0043] Such as figure 1 As shown, in general, the host needs to communicate and set up with the peripheral device through a specific communication port (such as USB, serial port, etc.) under the premise of following a certain communication protocol.
[0044] When the peripheral device generates an interrupt, it will call the corresponding interrupt service subroutine to realize the function. If the host computer wants to implement an interrupt response application, it must know that the interrupt has been generated after the peripheral device generates an interrupt and before calling the corresponding interrupt service subroutine, and execute the corresponding interrupt response accordingly.
[0045] Such as figure 2 As shown, according to the above idea, after the peripheral device generates an interrupt and before calling the corr...
