Follow the steps to install keil uVision4 Note: The following two points are important and may determine whether the ins

Precise delay of c51Some friends suggested that the accuracy of 51 Single-Chip Microcomputer delay program using C language is not enough. In fact, the C language is eventually compiled into an assembly language for running, so the assembly program will be very large, this affects the precision of latency. Here, we will post some online materials for your reference.The following content is reprinted:A Simple Study of 51 MCU Keil C delay ProgramBy: inf

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

target "XXXX ") in the C/C ++ tab, add the following statement to define: __fpu_present = 1 ,__ fpu_used = 1. In this way, the code for starting FPU is added during compilation, and the CPU can use FPU correctly and efficiently for simple addition, subtraction, multiplication, division, and so on. However, this is far from enough. For complex operations, such as trigonometric functions and operators, if math is used for programming. h header file, which cannot improve efficiency: Because math.

ccount[5];}A1;struct Taga A2;This struct int variable takes up the longest byte (the array cannot be counted by the base type, char ccount[5] or 1)---4 bytes, so the struct's self-aligning value is 4. When the program allocates memory, it allocates memory from the default specified alignment value and 2 values of the struct's own alignment value, which is our sizeof (A2) will get a length of 16 instead of 9.In the VC default value is 8, the default value in

(2) After the environment is set up, download the program, 1. Construction of the development environment The NRF5182

and the combination of micro-holes used to penetrate these layers, the resistors and capacitors can be buried under the surface, and the trace density on the unit area increases nearly one times, thus reducing the size of the PCB. The narrowing of the PCB area has a huge impact on the topology of the traces, which means that the reduced current loop, the narrowing of the branch trace length, and the electromagnetic radiation are approximately proportional to the area of the current loop, while
