I have read the article about the transplantation of UC on the C51 by Mr. Yang from julong. However, with the understanding of UC, it is found that the task function in the porting program of instructor Yang cannot pass parameters, so he tried to change it. The running process of UC is as follows: 1. osinit () function initializes idle tasks. If there may be statistical tasks, of course, there are PCB and event idle lists (I think anyone who knows UC knows how to get started ); 2. ostaskcreate

Recently, I am very interested in iOS reverse engineering. Currently, iOS reverse engineering books include Hacking and Securing IOS Applications and iOS Hacker's Handbook. The Chinese books include iOS reverse engineering: analysis and practice: the programmer Nian Qian's iOS security attack and defense series english blog includes: Prateek Gianchandani's iOS Security Series blog which involves ARM assembly, but it is only widely used, the ARM assembly on iOS is not described in detail. Therefo

cannot be predicted. Therefore, in scenarios with high real-time requirements, compilation and C joint applications are also required. But is there a latency program that needs to be implemented through assembly? To find this answer, I did an experiment.When using C language to implement latency programs, the first thing that comes to mind is the commonly used loop statements in C. The following code is frequently seen on the Internet:Void delay2 (unsigned char I){For (; I! = 0; I --);}How high

registers cannot be accessed concurrently, and the processor state and operating mode determine which registers are available to the programmer. L Non-grouped universal register R0-R7 R0--R7 in 16 data registers are non-grouped universal registers that are used to hold data and addresses . L Packet General register R8-R15, processor mode determines physical register --r8-r12 Register: Fast Interrupt and o

= tag_next (tag_array ); ...... Tag_array-> hdr. tag = ATAG_NONE; Tag_array-> hdr. size = 0; Tag_array = tag_next (tag_array ); Finally, copy the linked list of kernel parameters to the default physical address 0x20000100 of the kernel. In this way, the parameter linked list is created. 4. kernel receiving Parameters The following describes how the Linux kernel receives the kernel parameters passed by BootLoader from the zImage Image Based on the ARM architecture. Shows the zImage startup pro

Most people who have studied single-chip microcomputer know the names of "Water lamp" or "horse lamp". The specific implementation effect is to display a group of changes cyclically according to a fixed rule. For example, if you use a byte length space to realize the "marquee", you can change the value of this Byte as follows: "0000 0001b"-> "0000 0010b"-> "0000 0100b"-> "0000 1000b"-> "0001 10000b"-> "0010 10000b"-> "0100 10000b" -> "1000 10000b"-> "0000 0001b" (loop) For example, to change th

"After the Olympic torch departs from Shandong sports square, it goes east to jingshi Road, then, after the Shandong Provincial Sports Bureau, the Jinan Municipal National Fitness Plaza, Quancheng Park, ShanDong TV station, Shandong University, Qianfoshan, Volkswagen Newspaper Group, Yanshan overpass, and the upcoming Jinan Olympic Sports Center, the end point of the transfer was arrived north of shunhua road-Qilu software park, with a total mileage o

Recently, people are talking about the Olympic torch passing through Kazakhstan, Russia, Britain, France, and the United States ...... Of course there are Tibetan independence. In sasttan and Russia, no Tibetan independence hinders the torch transfer, but in Britain and France. Is Russia independent of Tibet?Measures can be taken to protect the Olympic torch. sec
