keil compiler

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 ea

Data Type Definition of the Keil MDK compiler. 1 # include "usart. h "2 int main () 3 {4 usartmediaconfig (); // serial port initialization, the following information is printed through the serial port 5 printf (" char: % d \ r \ n ", sizeof (char); 6 printf ("unsigned char: % d \ r \ n", sizeof (unsigned char); 7 printf ("short: % d \ r \ n ", sizeof (short); 8 printf (" unsigned short: % d \ r \ n ", size

A few days ago into the hands of a J-LINK, because the H-JTAG after all on the MDK support is not too perfect, for example, with the Download button on the Keil MDK burning program, not directly can burn in, instead, the H-Flash software is popped up, and then the file is manually selected for installation. In addition, the single-step debugging with h_jtag is easy to run inexplicably. Fortunately, J-LINK is not too expensive (I mean domestic imitatio

Transferred from: http://blog.chinaunix.net/uid-20734916-id-3988537.htmlKeil and MDK coexist, follow these steps:1 Install Keil C51 First, install directory to: "D:\Keil2" (I was installed on the D drive)2 Reinstall RealView MDK, directory: "D:\Keil"3 Copy the C51 folder under Keil2 to Keil4 Copy and paste all the files under Keil2 under UV4 (or UV3) to the UV4 folder under

The same shoes that used Keil know that now the Keil can be output by default. AXF debug files and the. Hex executable file that can be checked for output, there is no output option for the bin (binary) file. However, there are times when it is necessary or customary to use the. bin file for Burn-write, one example below:1. users who have been using ads habitually use the. bin file;2. some of the applicatio

original author)1 Problem Review and Analysisas mentioned in the original text: in the actual work encountered on the same port repeated continuous reading, Keil C51 compilation did not achieve the expected results. The author of the original C compiled assembler analysis found that the same port of the second read statement is not compiled. But unfortunately the original author did not analyze the reasons for not being compiled, but rushed to use so

Keil Optimization Level settingOptimization level description (for reference only):The Code optimization bar is used to set the C51 level of optimization. There are 9 levels of optimization (as written in the book), and the high level of optimization includes all the previous levels of optimization. The various levels are described below:0-Level optimization:1, constant folding: Whenever possible, the compiler
