let's talk about how to introduce the bank into existing projects.1) Right-click the project name in the left lane of the Keil IDE and click "Add Group ..." To add sub group, take four banks as an example, to ensure that there are 4 sub groups under the project name. Of course, if you already have groups, you don't have to add any more. In general, we bank0 also called Common, its address range is 0x0000~0x7fff, the other bank#n range is set to 0X800

When making changes to the driver name of the USB device, the firmware needs to be modified with the Keil software and the. iic files are burned to the external eeprom in cy7c68013a, and the. hex file Keil generated can only be burned into cypress RAM.This configuration is also very simple, first find the Bin folder in the installation Kit, find the Hex2bin software. Such as:After locating the application,

stack of Keil tools 2 ========================================= The local variables of the function are stored in the "stack", and the stack is in English: stack. Stack size, we can set in the Stm32 startup file, with the Battleship Stm32 Development Board for example, in Startup_stm32f10x_hd.s, the beginning is:Stack_size EQU 0x00000800Indicates that the stack size is 0x800, which is 2048 bytes. In this way, the CPU processing task, the function loc

I wrote a function, I want to put it in the 31st area of Flash, the address is 0x0801f000 this place, I searched a method on the net. Although reached the effect of the online said add a __at, and contains the header file # include "Absacc.h" This method applies only to the absolute definition of an array. Here's how: U8 Testbuf[8] __at (0x0801f000) ={0x34,0x66,0x03,0x34,0x23,0x77,0x77,0x77}; But what about. For a function. For example void __at (0x0801f000) test_abc (void) {... Own code}; This

"Automatically set heap size when using Keil's Microlib" Keil compiles the project, you can use malloc if you use the Micro-Library microlib. A heap management module for the internal location of the micro-Library.The RAM size of the chip is fixed, the front is divided into global variables, and then to the heap and stack, which is the general development method.But in the process of developing the project, the market encounters a variety of problems

Transferred from: http://blog.sina.com.cn/s/blog_980e19e00101b5dh.htmlSometimes precise delay is required, such as the 18B20 temperature sensor is very strict in timing requirements and must be accurate to the microsecond levelFirst, with the NOP functionIn Keil C51, call the library function directly:#include//declared void _nop_ (void);_nop_ (); Produce a NOP instructionFunction: For the delay is very short, requirements in the US level, the use of

I tried to port the STM Keil project to IAR several times. Fortunately, all of them succeeded. Here I will write down the notes during the porting process... The first step is to first create a project folder PWM, and then create several subfolders in the folder: User, Inc, and startup. Of course, we have to copy the official library directory of STM, so there are four folders under the project directory (in fact, creating a few folders is random, jus

Keil C51 is a compiler compatible with ansi c. The ansi c Specification specifies that the default data types of decimal Integer constants are int, long int, and unsigned long Int, which of the given constants depends on the actual size of the constant. If the constant is between-32768 and ~ Between 32767 and are processed by the int type. If the processing by the int type overflows, consider the long Int or larger data type unsigned long Int. In shor

Label: Style Color Io use AR for strong data spHow to Reduce the code compilation size of Keil-C: (reduce by optimizing the code) 1.1 perform less multiplication and division operations, and use left/right shift to realize multiplication and division Eg, common: a = 0x80*4; Optimization: a = 0x80 1.2 use the short type instead of the long type without affecting the operation Eg, common: int; Optimized: Char; 1.3 Use unsigned data whenever possible Eg

Putchar in Keil C, take 8051 as an instance, putcharkeilIn Keil C, it is necessary to implement char putchar (char c), or the powerful function printf wocould not work.We shoshould notice in here: new line command for serial output be "\ r \ n" (line feed: LF, 0x0a + carriage return: CR, 0x0d ), not only "\ n" in Keil C.I do not want to write too much tedious wor

In November 2014, the author wrote a: based on the C programming language, how to Keil software in the modular programming document , and upload to Baidu Library. And in May this year, the content of the document was updated and perfected. In the beginning to practice programming friends a reference, send this blog, to facilitate more friends to see. If you reader feel a bit of a role, you can help continue to spread, I am grateful. The author level i

As shown in the picture, many students may encounter the "File has been changed outside the editor, reload?" In the image above when using Keil. hint, very annoying. When you encounter this prompt, first of all do not depressed, please read the path and name of the file first. For example: The filename of this hint is UCOSII+STM32+12864.AXF, and then look at the following image: You see the file name shown in the figure above UCOSII+STM32+12864.AXF

Take the small Wagon program for a freshman game. As you can see, my delay function is used in the assembly. However, the target cannot be created after compilation. Now everyone right-click on the left side of the workgroup 1:source Group 1. Then click on the first options for group ' Source Group 1 '. Set the dialog box to the right of the red circle two options points two times, making the tick black. Click OK to compile. If you have two warnings at compile time: The warning rea

This is an external interrupt in the Keil MDK environment.ProgramIt is really convenient to use H-JTAG and MDK for debugging because Keil is used and ADS is not used.

Code is the keyword of the Keil C51 extension, and the code-modified variable will beinto the code area. But the const keyword in c also seems to have the function of defining variables that cannot be changed, what is the difference between these two keywords?To find the const in the Help manual, you can find the following description1 Variables declared with the const type qualifier alone is stored in the "Memory Area" (data, Idata, XData, and so on)

After some analysis, Kung fu is not a conscientious, find Global.prop This file, this file is used to save users on the Keil interface and font information such as parameters, If you want to save or share beautiful settings , you can just replace the file. Don't talk nonsense directly The global replica is a backup of the original configurationThis is my configuration, like can save the following code, replace the original global (original directly

Keil upgrade to 4.72 version, Jlink began to prompt firmware upgrade, is very irritable, but look on the internet can be said to replace the previous version of the Segger file to Keil the latest version of the Segger file, it can be used, I tried the next, it really works ha, below to share the operation process.Save the previous 4.6 version of the Segger file, the version using Jlink no problem, Keil6.0 i
