1. Explanation of STM32 low power mode Some devices, such as wearable devices, have very high requirements for power consumption. For example, a watch needs to run normally when I check the time ...[Details]

introduction Since the 1990s, with the continuous reduction of the feature line width of integrated circuits and the corresponding increase in chip density and operating frequency, reducing power con...[Details]

With the rapid development of electronic technology, single-chip microcomputers have also entered a new era. More and more single-chip microcomputers with different functions have provided many new me...[Details]

    Preface     An embedded system is a special-purpose computer system that is application-centric, based on computer technology, and whose software and hardware can be tailored to meet the strict r...[Details]

I won't go into detail about what NFS is, but the definition is as follows: Network File System (NFS  )  is  a mechanism for mounting partitions (directories) on a remote host to a local system via a ...[Details]

In "51 Operating System Study Notes (I)", we have mastered the implementation of parallel multitasking, and how to use the modification of sp content and the call of ret at the end of the subroutine ...[Details]

What are the advantages of PIC series microcontrollers? Since I came into contact with PIC microcontrollers in 1995, I have been keen on the development and application of this type of microco...[Details]
