I used a virtual printer driver to convert a word document into a bmp image. Once an image is detected, a dialog box will pop up to process the image of the current document. However, when the first f...
We usually use C language to develop microcontroller programs. Why is C language more convenient than assembly language? The reason is that the C compiler is doing a lot of trivial organization and tr...
After selling its mobile phone business to BenQ last year, Siemens is once again caught up in rumors of splitting its business units. There are reports that Motorola is interested in acquiring Siemens...
I was recently writing a driver for the LIS25BA bone vibration sensor. The development platform was stm32769i-disc. When reading the manual, I encountered several problems with the sensor chip:1. The ...
I found a memwatch tool. When compiling a single file, I only need to define memwatch-related variables in the compilation statement. But when compiling a large number of files, how should I modify th...
Assume that data is read from 8-bit AD (if it is a higher-bit AD, the data type can be defined as int), the subroutine is get_ad();
