StorageManager library provides access to the storage area "pseudo-contiguous blocks" (typically used for different functions and purposes). That's why we have different functions assigned to the storage area:1, parameter area;2, the flight area limit point data area;3. Waypoint data area;4. Aggregation point data area.See also: libraries/storagemanager/storagemanager.cpp, we can see the partitioning of the storage area:Const Storagemanager::storagearea Storagemanager::layout_copter[storage_num

designers to find a FAT open source file system that is easy to transplant and use, occupies relatively small hardware resources, and has powerful functions. FatFs Module is a completely free and open-source FAT file system Module designed specifically for small embedded systems. It is fully written in standard C language, so it has good hardware platform independence, it can be transplanted to the 8051, PIC, AVR, SH, Z80, H8, ARM and other series of

The. c file in the font has the following similar structure: Gui_const_storage gui_font gui_font8_1 = {Gui_fonttype_prop/* type of font */, 8/* Height of font */, 8/* space of font y */, 1/* magnification x */, 1/* magnification y */, { Gui_font8_1_prop}, 7, 5, 7}; We extract this structure, and specify the absolute address for the remaining font. c file to com

square Calculation of floating point numbers is achieved by calling subprograms, in an AVR microcontroller that comes with a hardware multiplier, for example, in atmega163, the multiplication operation can be completed with only two clock cycles. Even in an AVR Microcontroller without a built-in hardware multiplier, the subprogram of multiplication is shorter than the subprogram code of the square operatio

It is a synchronous Serial Peripheral Interface that uses the ICSP header (Number 6 in Figure 1.4 ).External interruption of ArduinoYun Interrupt allows the processor to run more efficiently. Yun has five external interruptions. They reuse ports 3, 2, 0, 1, and 7 respectively. The interrupt details will be introduced in chapter 4th, which will not be described here.Two microprocessor specifications of Arduino

How to optimize C language code (programmer must Read)5, reducing the intensity of the operation can replace the original complex expression with an expression with a small operand but with the same function. as follows: (1), to find the remainder operation. A=a%8; can be changed to: a=a7Note: Bit operations can be done in only one instruction cycle, while most of the C compilers '%"operations are called subroutines to complete, the code is long, the execution speed is slow. In general, the only

application design of serial interface SPI interface The synchronous serial three-wire SPI interface is used, which can be conveniently connected with the peripheral of SPI Communication protocol or another AVR MCU, realizing high speed synchronous communication in a short distance. ATMEGA128 SPI uses hardware to achieve byte-oriented Full-duplex 3-line synchronous communication, support host, from the machine and 2 different polarity of the SPI time

following example: Old Code: long factorial (int i) { if (i = = 0) return 1; Else return I * factorial (i-1); } New Code: static long factorial_table[] = {1, 1, 2, 6, +, 720 * * etc * *}; long factorial (int i) { return factorial_table[i]; } If the table is large and hard to write, write an init function that temporarily generates a table outside of the loop. (2), to find the remainder of the operation a=a%8; Can be changed to: a=a7; Note: bit operations need only a single instruction cycle to

1. Create an installer and package it with VB.Use iexpree2.0 to compress multiple files and select "Unbind files and run the installation command" to generate a "compressed running File"3. Sign the "compressed running file" and use signcode (how to generate a. Cer Certificate file before that)4. Write the If your VB project has a version number, replace it with your version number in version =. If your software is installed on another machine, the version is not as high as your version number,

less readable (personal opinion). VC provides us with another way, that is, adding the following before the file: # Is Pragma once very convenient? 3. Invalid warnings sometimes we have to forcibly convert the variables, which leads to a warning from the compiler. Especially in C ++, the type check is stricter than C. Although this does not affect anything, it seems so uncomfortable-I mean to do this, what do you warn me! :) At this time, you will see the Warning type, for example, "Warning c43
