In the debugging state of Keil C, how can we observe the operating status of various internal and external peripherals? How can we modify their settings? Answer: In debugging state, click on different peripheral options under the Peripherals menu to display or hide the corresponding observation windows. For example, to display the Timer 0 window, … Read more
By default, Keil/MDK can generate ***.axf and ***.hex files. To generate a ***.bin file, you first need to know what tool is used for this process. The fromelf.exe conversion tool is part of the development suite provided by ARM, and it is already located in the installation folder when you install MDK. This tool is … Read more
After working with microcontrollers, I transitioned to ARM and initially used the ADS 1.2 compiler. I used it for a while because the old program of the project I took over was compiled with ADS, and most of the department was using it. When learning about microcontrollers, I used the Keil C51 compiler, and the … Read more
Using Keil MDK, I tried an example for STM32F107. After opening and compiling, the compilation succeeded, but the linker indicated that there were 5 functions undeclared. However, upon reviewing the files, it was clear that the header files were included. Why was it still not working? I also tried using extern declarations, but that did … Read more

Open the download software in this file (stc-isp-15xx-v6.18-Beta2). 2. Click ① to find the associated settings for Keil ②. 3. Click on the Keil settings as shown in the above image, … Read more
MRI Imaging Methods The MRI image is formed by reconstructing signals generated from the resonance of hydrogen nuclei in a magnetic field. Therefore, the concept used in MRI images is “signal,” rather than the “density” concept used in CT images. In MRI images, lesions are described using the term “abnormal signal focus.” Because the imaging … Read more
1. NPT is a general-purpose American standard tapered pipe thread with a thread angle of 60°. PT thread is a British standard tapered thread with a thread angle of 55°, commonly used for sealing. British pipe threads are fine threads; coarse threads have a larger thread depth, which severely reduces the strength of the external … Read more
