After work, I switched from a single-chip computer to an arm. At the beginning, I used the ads1.2 compiler for a while, because the old program I took over was compiled using ads, and most departments were using it. when learning SCM, we use the Keil C51 compiler. ads and this compiler cannot be compared in terms of ease of use. later, we gradually learned that Keil has been acquired by arm, and now

Problem description: Use the Keil C51 compiling environment with a font LCD. some Chinese characters cannot be displayed when such a statement is used: uchar code coun_show1 [] = {"Please enter the first operand"}; the number of Chinese characters will not be displayed, replace the preceding Chinese characters with simplified Chinese encoding, for example, uchar code coun_show1 [] = {0xc7, 0xeb, 0xca, 0xe4, 0xc8, 0xeb, 0xb5, 0xda, 0xd2, 0xbb, 0xb2, 0x

ClickLink to Keil V3 to add the STC series single-chip microcomputer library file method + header file library Add a single-chip microcomputer database, you can chooseSTCSingle-Chip Microcomputer, without affecting the use of the original database. Procedure: 1. Download the STC database for Keil and rename it STC. CDB. Place the files in the folder to the corresponding folder. If there is no STC folde

Keil compiles the project. If microlib is used, you can use malloc. A heap management module is located inside the micro-database.The memory size of the chip is fixed. The memory size is divided into global variables and allocated to the heap and stack. This is a general development method.However, during the development project process, the market encountered various problems. Stack penetration into the heap, or the heap is not large enough, which is

Ⅰ, write in front This article uses the current (November 2016) Latest version of the Keil (mdk-arm) V5.21A development environment , taking the STM32 processor as an example to tell you about the detailed process of creating a new software engineering. Keil (Mdk-arm) V4 and V5 new software engineering are basically the same, this article is also suitable for the V4 version of the new software engineering.

Generate a. Lib file for a single c file under the Keil realview MDK Having struggled for a day, there was no clear question about the complete web page. Isn't it too simple for everyone to say? In most cases, the project is simply converted to. Lib. Under Project-> options for target-> output, select create library. However, the generated lib file is huge. The final lib generated by the project I compile now has 2.6 MB. Later I found inspiration (

In Keil C, if no defined function is explicitly called, such a warning will appear. When such a warning occurs, you can ignore it because it does not affect other parts. However, we know that even if this function is not called, Keil still concatenates it into the wholeProgram, But a waste of Rom is not distressed. Most importantly, the variables in this function are not included in the scope of the analysi

★Software Used ● Keil Software Development ● Virtual serial port Software ● Serial port debugging Assistant★Software Introduction 1. virtual serial port Software For a laptop, virtual serial port can be used to simulate a real serial port without a serial port. The program can use the virtual serial port to exchange data with other serial ports. Virtual serial ports driver is a very powerful virtual serial port software. Two virtual serial ports can b

Embedded OS entry notes-use RTX as a case: 10. Support for RTX debugging of Keil Debugging is an important part of software development. For embedded development, this part is actually dependent on the support of some hardware resources (hardware debugger. Debugging of traditional embedded systems depends on breakpoint and single step through ). However, the arm cortex-M series chip has strong support for coresight chip debugging. It is actually a sma

Keil is a god compiler. For example: 1> the compiler prompts "expression with possibly no effect", indicating that your current language is useless, as shown in figure The following statement is used in Preprocessing: # Define s2tb8 (A) (s2con 0xf7) | (a) The solution is as follows: # Define s2tb8 (a) s2con = (s2con 0xf7) | (a) Then, the compilation is successful. OMG. If Keil doesn't remind me,

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
