In practical application circuits, in order to increase the input resistance of the inverting input proportional operation circuit, the T-type resistor network in the circuit shown in the figure is of...
The company has a mature architecture, but it has problems for me. Originally, LCLK was directly given by an external crystal oscillator. I entered the FPGA and then gave the 9054 chip through the FPG...
Millimeter waves usually refer to electromagnetic waves with a frequency band of 30~300GHz and a corresponding wavelength of 1~10mm. The operating frequency is between microwaves and far infrared wave...
As far as I understand, ChipWatcher should only allow one clock source to be selected. However, in actual use, it seems that even after selecting multiple ones, there is only one in the end. In this c...

I recently upgraded MDK to V5.25 and found that there are many libraries in the Managing Run-Time Environment. Compared with the past, it is much better, from the bottom-level driver to the upper-le...[Details]
Friends who work in the photovoltaic industry, do you still remember the hard work on June 30 last year? How many people worked late into the night for months in a row just to connect to the grid a...[Details]
1. Basic Concepts of LCD/LCM The structure of Liquid Crystal Display (LCD) is to place liquid crystals between two parallel pieces of glass. There are many vertical and horizontal fine wires between...[Details]
The analog watchdog of the ADC is used to check if the voltage is out of bounds. It has two upper and lower bounds, which can be set in the registers ADC_HTR and ADC_LTR respectively. The library fun...[Details]
ADC Introduction: ADC (Analog-to-Digital Converter). That is, converting analog signals into digital signals for processing. When storing or transmitting, analog-to-digital converters are almost ...[Details]
The photovoltaic industry has become a new business card for China to the world. It not only represents China's leading technology, but also constantly breaks various records with its development spee...[Details]
Summary of STM32 peripheral DMA usage: 1. Select DAM mode according to your needs: (1) Circular mode—DMA_Mode = DMA_Mode_Circular (2) Normal mode—DMA_Mode = DMA_Mode_Normal 2. For Chanel3 of DMA1, t...[Details]
T1 or T2 are two timers/counters of MCS-51 microcontroller. The first method can use two timers/counters to generate rectangular waves. In order to save interface resources, the second method is used...[Details]
