has been using Keil to write some of the microcontroller program, but has not done some optimization of the project structure, and sometimes open the project after the document structure level more complex looks very uncomfortable, so here are some of my ideas:First, the structure of the file to be divided into bin Buil_keil include library lst obj source startup such directory, such asThis allows the generated. bin file to be placed down the bin.

The basic steps for debugging the Keil program in internal RAM are already available on the Internet, so I will not repeat them here. You can find a lot on the Internet. However, sometimes the internal RAM is not enough, so you need to load the program into the external RAM for debugging. In this process, various problems may occur, here, I will summarize some of the problems I have encountered and the areas that need attention, hoping to help you.

I read a lotArticleAnd writes are very simple (actually very simple :)). A detailed tutorial is provided. 1. Use vspd to connect two virtual serial ports on the PC. I connect com2 and com3. Click ADDR pair. 2. We can see that two virtual serial ports are connected together on virtual ports. 3. The virtual serial port is ready. First, you can directly enter the command for debugging. We open the Keil MDK and set it to the simulation m

The unused file storage directory compiled by the program has been set to the Obj folder. When compiled, you will find that there are several files in the obj directory, about 100 files, occupying space will be nea

After the project is successfully compiled in Keil, the following message is printed in the Bulid ouput window below:Program size:code=6320 ro-data=4864 rw-data=44 zi-data=1636The meaning of the representative:Code: The size of the bytes in the programRo-data: Instruction and constant size defined in the program (Personal understanding: Read only)Rw-data: The variable size initialized in the program (Personal Understanding ": read/write)Zi-data: Unini

STM32 Keil Software Setup program write start address selection STM32 Series MCU, here take CORTEX-M4 as an example, when we debug online, we usually set the program to write the start address and size. This size is typically 0x08000000, which is the mapping address of the internal flash. But some products start from 0x08020000, which is why. is because in the 0x08000000-0x08020000 this space is the boot program, that is, the boot program is stored f

Fixed repeated variable definitions when multiple files are created in Keil Extern is used in many places in the C/C ++ language. However, if you do not really understand its meaning, it will bring a lot of trouble to programming, let's explain it in detail. For small programs, there is usually only one C file and one head file. We usually define global variables directly in the C file and add int I Definitions before the program. If you want to de

Label Idatalen equ 80h ; The length of IDATA memory in bytes. Here Idatalen is just a label, and IDATA is not the same thing! If you want to, this procedure in the idatalen you can change to dog ah, pig ah, playboy ah these markings (in fact, my ideal is the life of pigs, not worry about eating and drinking, carefree, but can not do), The above s

The target configuration diagram for the options for target and the scatter file for the project file.When we modify the address in read/only memory areas and read/write memory areas in target, the address in the scatter file is automatically changed after compiling the project file.To observe the relationship between the two, it is not difficult to find that the starting address and size in the read/only memory areas correspond to the load address of the image file in the scatter file and the s

Background: The code accumulated more, everyone may have tried to write a library, convenient to call, my initial approach is to put the usual functions into one. c file inside, to use when you put a. C added to the group inside, this method is very troublesome, each new project will add half a day.Objective: To write some functions into the form of a library file, to the form of a header file function interface, so that other projects can be called directly.1, the new 1

Keil some function keys do not have the default shortcut keys, if commonly used, more convenient approach is to set it into their own habit of shortcut keys. Here's how to customize shortcut keys: 1. Find the location of the function you want to define, such as I want to define "Comment Selection" annotation Select the target function, find its location:Edit:Advanced:Comment Selection; 2. Select edit:configuration, configuration options; 3. Select
