Although the. NET Micro Framework is easy to learn and use, it is difficult for some applications that require real-time and high performance. After all, the upper-layer applications of. NET Micro Framework are interpreted and executed by the lower-layer CLR (TinyCLR). It is inevitable that the execution efficiency will be discounted. GHI (a major manufacturer of. NET Micro Framework hardware products outside China) provides a RLP solution (https://www.ghielectronics.com/docs/50/rlp-enhanced ).

Source: Keil MDK How to set a non-0 initialization variableSome industrial products, when the system reset (non-power-on reset), may require to hold the data in the pre-reset RAM, used to quickly restore the scene, or not due to the instantaneous reset of the field equipment restart. and Keil MDK by default, any form of reset resets the uninitialized variable data in the Ram area to zero. How to set a non-i

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 Keil MDK has become an official arm compiler, so we

Keil MDK version: v4.03. For more information, see my other blog posts. PC-Lint version: v8.0 There are many powerful functions of PC-lint on the Internet. I don't want to repeat them here. I just want to say: it can be tested by PC-lint.ProgramIt may not be a problem, but the quality improvement is self-evident when the PC-Lint test program is passed. First, install the Keil MDK and PC-Lint sof

In the integrated development environment of realview MDK, debugging files in *. axf format and executable files in *. hex format can be generated by default. Although the files in these two formats are very helpful for downloading and debugging the ulink2 simulator, ADS users are more accustomed to using *. bin files, even some embedded software developers already have *. debugging or burning tools for Bin files. To fully utilize the existing tools a

I. On use_stdperiph_driver issues in STM32 MDK Beginner STM32, when building a project using STM32 firmware library in RealView MDK environment, beginners may encounter problems with compilation. The following warning or error message appears: Warning: #223-D: function "Assert_param" declared Implicitly;assert_param (Is_gpio_all_periph (Gpiox)); In this case, we need to add use_stdperiph_driver, STM32F10X_

Use MDK for programming. If you have defined a useful function but no explicit call is made, MDK uses the entire function in the default mode.ProgramAlways Delete to save Rom. For example, if you locate a function in 0x00002000 of Rom, assume it is void test (void), and then use the function pointer to call it: Void (* userprogram) (); // function pointer Userprogram = (void (*) (0x00002000); // locat

Note that it is not as easy as writing a pen. To make it easier to view code and reuse code again, we will post the S3C2440 UART driver code here.

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 (
