-II contains a lot of such code as (1) (2) and (3) as seen elsewhere: (1) pc_vectset (0x08, ostickisr); // install the clock service program to complete the time-out process for executing functions such as ostimedly in each task. (2) pc_settickrate (OS _ticks_per_sec); // set the clock frequency. You need to write the assembler program based on the CPU to initialize the registers of the timer. (3) pc_vectset (0x80, osctxsw); // The Task Switching during software interruption. Because osctxsw is

to further enhance the oal layer functions. This method is also commonly used in oal layer development. Complete the basic functions first, and gradually add other functions after the basic functions are correct. Step by step, even if an error occurs, it is easy to find the error location for troubleshooting. 3. Enhance oalThe second stage aims to make full use of the hardware resources on the board and strengthen debugging methods. It includes interrupt, kitl, Ethernet port debugging function,

Touchpaneldisable This function is opposite to the touchpanelenable execution condition mentioned above and provides the ability to stop devices. The called ddsi functions include: Ddsitouchpaneldisable The execution of this function is as

/*** When copying the instance code on major IT websites such as csdn and javaeye, there will always be a series of lines before each line of code * It is too troublesome to manually delete the sequence one by one, so I wrote a method to automatically delete * For example, the copied code: * 001 the first line of code * 002 The second line of code * 003 the third line of code ** @ Param path01 the code path to be replaced * @ Param path02 the path to the replaced Code * @ Param index prefix numb

, and are at the interruption level used by the operating system to complete special method calls. Unlike device interruptions that process hardware operations and higher-level clock and processor interruptions, these two levels of interruptions are designed to achieve asynchronous function calls, therefore, the operating system itself is highly dependent on them. APC is not discussed here for the time being. I will have the opportunity to write another article to discuss it later :) DPC functio

How can we make Inter-Domain and non-domain reception unavailable, but instead of a default route? In this case, we need to create the detail area.
