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

I installed analyticdb in windows. It was a headache. I had to use it in compatibility mode. Even if this happens, there is a problem with jlink. I had no choice but to give up ads, but I had a lot of materials to develop with ads. Finally, I tried to use Keil and searched the internet for the information. I found that some people did the same thing. So I tried to find out what they did, but it was not a success. Finally, I had to wait for a while to

Follow the Keil for ARM tutorial to create a project, write the main function, and operate gpio,ProgramThere is no problem with compilation after writing, "At91sam7x. axf"-0 error (s), 0 warning (s ).

The Keil uvision (MDK v4.7) was run on Ubuntu 12.04LTS a few days ago. The process is also smooth, sharing the next steps to the needs of friends. A screenshot of the previous installation (I'm using the old-fashioned Gnome classic interface) to see Keil uVision4 in the Wine menu. In fact, using wine (HTTP://BAIKE.BAIDU.COM/LINK?URL=8TJGR-T30E9PQ-H4MOY_55BL__W8HDLNIKYPZD9M8G7WYFTIJL-S3S4LIGGBA_MJ) to ins

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

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

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,
