1. Principle 1. Infrared emission protocol There are many infrared communication protocols. This experiment uses the NEC protocol. This protocol uses PWM modulation and uses pulse width to represen...[Details]

　　Recently, the US embargo on ZTE has attracted much attention. Let's take a look at the relevant content with the automotive electronics editor. 　　On April 16, local time, the U.S. Department of Co...[Details]

Today, under the guidance of a low-level expert, I learned how to configure the PWM module! Woof! First open the file configured last time, as follows:  Then, we need to use TIM1 to set PWM:  Then,...[Details]

Function List and Notes (lower-level driver part) 1. IO port initialization: control IO and communication IO. Control includes power control, reset and low power mode. Communication is the serial po...[Details]

Recently, the "Smart Photovoltaic Industry Development Action Plan (2018-2020)" jointly issued by six departments has put this concept on the forefront. Photovoltaic smart solutions will become the ne...[Details]

　　At present, the Beidou system has achieved industrial breakthroughs and leapfrog development in five major areas, including the automotive OEM market, smart phones, and high-precision applications....[Details]

Superconductors have physical properties such as zero resistance effect, Meissner effect and Josephson effect, which make them have broad application prospects and unparalleled advantages in many b...[Details]

I used the bit definition in my 51 program: bit flag. After defining it this way, I ran the program and downloaded it to the circuit board. I found that the flag was not the value I set, which led to...[Details]

The Vatican Secret Archives is one of the world's greatest historical collections, but many of its documents have never been transcribed. Recently, a project called Codice Ratio used a combination...[Details]

    The STM8L contains a 12-bit ADC with 25 input channels, including an internal temperature sensor, an internal reference voltage     As can be seen from the figure above, there is an internal re...[Details]

Interrupts and timers implement a 24-hour clock. The program is as follows: #include reg52.h   #define PORTLEN P0   sbit bit_select = P2^0; sbit seg_select = P2^1;   unsigned char src = {0x3f,0x06,0...[Details]

The frequency calculation formula of the PWM wave generated by the output comparison mode of the timer is: 72M/((2*(arr+1))*(psc+1) ) For example, if you set: PWM_Init(1000-1,72-1); (PWM_Init(arr,psc...[Details]

The circuit shown in the figure requires that the light is off when the machine is turned on. Press the button once, and the light D1 will turn on and automatically turn off after a delay of 10 secon...[Details]

Requirements: Set timer T1 as an external event counter, count 500 pulses every time, then switch T1 to timing mode and output a positive pulse with a width of 10ms at P1.2. Over and over again. A...[Details]
