Photovoltaic inverters are the core equipment of photovoltaic systems. Their main function is to convert the direct current generated by photovoltaic modules into alternating current that meets the...[Details]
The status of interrupts in developing embedded systems is absolutely unquestionable. In the era of C51 microcontrollers, there were only 5 interrupts, including 2 external interrupts, 2 timer/counte...[Details]
1. About FPU transplantation As long as the chip has FPU function, the use of FPU is generally enabled by default. You can also select it in the Options tab; 2. About the transplantation of DSP li...[Details]
introduction In the general project development process, two or more microcontrollers are often required to communicate to complete data transmission. For example, a quadcopter wirelessly transmits d...[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]

1) ADC multi-channel acquisition: (Multi-channel acquisition must use scanning mode. In scanning mode, the channels of the rule group share a register, so DMA transmission must be used; to prevent da...[Details]
1. What is PWM What is PWM? Professionally speaking, it is pulse width modulation. In layman's terms, it is the continuous output of high and low levels. For example, the microcontroller outputs...[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]
In the packaging process of a production line, every time the conveyor belt of the production line delivers a product to the packaging machine, the "SP" terminal outputs a pulse to the T1 terminal of...[Details]
Assume that the crystal frequency of the microcontroller is 6MHz. It is required to use timer 1 in mode 0 to generate a continuous square wave pulse with a period of 500us, and output it from P1.0. T...[Details]
