Abstract: In view of the diversity of fault characteristic signals, different signals need to be measured and analyzed for mechanical equipment to improve the rationality of diagnosis. To this e...[Details]
Introduction: For the ARM system, the mixed calls between functions written in different languages follow the ATPCS (ARM-Thumb Procedure Call Standard). ATPCS mainly defines the rules for passing p...[Details]
Working principle of the circuit : The temperature measuring resistor RT is connected to the input end of the control gate D1. It and the resistors R1, R2 and RP are adjusted by the voltage divide...[Details]
On the one hand, this circuit can avoid the problem of having to use expensive inductor coils in general oscillation circuits. On the other hand, it can avoid the problem of using double potentiomete...[Details]
(1) When measuring current or voltage, there is no indication at one or several levels, but the other levels indicate normal. The reason is that the clamp meter's fastening switch screws are loose, o...[Details]
Everyone knows that if a Linux application wants to access the kernel, it must use a system call to switch from usr mode to svc mode. Let's take a look at its implementation process. System call is...[Details]
