I think it is annoying to use library functions, and the efficiency is very low. For example, to cancel the Schmitt trigger of the AD port, each port must be adjusted once,ADC1_SchmittTriggerConfig(AD...
Hehe... Those who have wrong ideas, please face the wall consciously... I am talking about naked open source, okay...I drew a board some time ago, made a few samples, wrote some stuff, not for making ...
Using C language programming, DSP sends SPWM wave, but why can't it enter the interrupt? nclude \"2407.h\" #include \"math.h\" #include \"float.h\" #define PI2 2*3.1415926 #define unit PI2/200 int fla...
I just started learning microcontrollers and it feels so complicated. I often miscalculate the time. When I see other people's programs, I feel a little dizzy when seeing DJNZ and JMP jumps. Does anyo...

Overview
In spectral measurement, photomultiplier tubes (PMT) and charge-coupled devices (CCD) are often used as photoelectric converters. PMT is used in slow-changing, high-precision spectral...[Details]
Abstract: The output of high-range acceleration sensor is less than 10 mV under the excitation of small signal. The noise of traditional test system may cover such small voltage signal, so that hig...[Details]
LED guardrail lights use fluorescent tubes or LEDs as light sources and continuous guardrails as carriers to form an approximately linear guardrail light strip. This article mainly introduces...[Details]
This article discusses the six design steps of LED lighting system design in detail: (1) determine the lighting requirements; (2) determine the design goals and estimate the optics; (3) the efficie...[Details]
The power consumption of a switching power supply includes fixed losses caused by parasitic resistances such as semiconductor switches, magnetic components, and wiring, as well as switching losses ...[Details]
