The most recent time is the I2C of stm32. I know that the I2C of stm32 is not easy to use, because I have used analog I2C, and I have also written the AVR I2C, that is, the twi hardware driver, so I want to try writing stm32 hardware I2C... In order to avoid the trouble caused by the Library, the standard

Floating Point operation has been a fixed point CPU problems, such as a simple 1.1 + 1.1, fixed point CPU must follow the IEEE-754 standard algorithm to complete the operation, for 8-bit single chip microcomputer has been a nightmare, for 32 single-chip microcomputer, there will not be much improvement. Although the Q-based processing of floating point numbers can give full play to the operational performance of 32-bit single-chip microcomput
Intel x87 FPU is designed for scalar floating point computing. It can compute single precision Floating Point (32 bits), Double Precision Floating Point (64 bits), and extended Double Precision Floating Point (80 bits, and complies with the ieee754 standard.
X87 FPU can work in 32-bit compatibility mode and 64-Bit mode. In both cases, the number of FPU data regi

With Git as a version controller, there are a number of possible workflows (Workflow), which makes us new birds unaware of what kind of workflow to choose in their actual work. Here we make a comparison of the most common git workflows, providing a reference for the corporate team.As you can imagine, the design of these workflows is only a reference, not an absolute rule. We're going to show you what the possible workflows are, so you can get the best of both worlds from a variety of different w
As the best dependency management system in the Java World, MAVEN hosts the jar package to the MAVEN Central Library and then uses MAVEN dependency as a common practice for various third-party libraries in the industry, if you want to share some of the libraries you have developed with others, You can follow the same routine. Gradle can be seen as an upgraded version of MAVEN, which uses Maven's best dependency management system, but also avoids the d
