Linux non-root user installation lamps
#Install lamps-7Aug19 (version: 2019-08-07) For convenience, I created a folder /home/hsiung/software/lammps. All files are downloaded and installed in this folder. cat /etc/redhat-release Use the cat command to check the version: CentOS Linux release 7.9.2009 (Core) 1. Download and install openmpi (mpich can also be used, see the installation process of lamps-10Aug15 below for details) openmpi […]
LED running water lamp experiment based on STM32 standard library function
1. A brief introduction to STM32 standard library functions and the difference from register programming The STM32 Standard Library is a set of software libraries provided by STMicroelectronics to simplify the process of developing applications on STM32 microcontrollers. It contains many commonly used functions and drivers that can be used to configure and operate various […]
[STM32F103 running water lamp lighting version 1]
? Foreword STM32CubeMX is a graphical configuration tool launched by STMicroelectronics. Relevant configurations can be achieved through fool-proof operations. It can ultimately generate C language code and supports multiple tool chains, such as MDK, IAR For ARM, TrueStudio, etc. It is particularly worth mentioning that TrueStudio has been acquired by ST and provides a completely […]
