芯片介绍：The TPS54260 device is a 60V, 2.5A, step down regulator with an integrated high side MOSFET. Current mode control provides simple external compensation and flexible component selection. A low rip...
We are a student group and want to use this voice chip, but the manufacturer's burning price is too high, so we want to burn it ourselves, but we can't find relevant information. So I would like to as...
How to use the serial port to receive a group of data (each group is 25 consecutive characters, and the last two characters are checksums) and use these data to update a global variable of an array ev...
I've been studying the CAN bus of STM32 recently. I wrote a program that only sends signals, but the oscilloscope can't detect any signal. My idea is that since it is only sending signals, there is no...
Use msp430g2231 and edge-triggered interrupt counting to measure frequency. Use external crystal oscillator 32768 as clock source. In order to improve accuracy, the interrupt program has made some mor...

1. Purpose Since the number of times the STM32 FLASH can be erased and written is limited, in order to protect our FLASH and extend the use time of the MCU, we can debug on the SRAM. SRAM is a ...[Details]
Unique device identifiers are suitable for: ● Used as a serial number (e.g. USB string serial number or other terminal applications) ● Use the unique ID as a security key when used in conjunction wit...[Details]
After we understand the use of libopencm3, we find that libopencm3 is only suitable for small projects. Its biggest feature is the convenience of USB. So when we configure large projects, is there a ...[Details]
Chip: STM32F107VCT6 Application Pin: THOUSANDS, RMII STM32CubeMX is very convenient to use ETH. The software comes with LWIP and configuration. This time, STM32F107VCT6+DP83848CVV is used. The MII a...[Details]
I used STM32CubeMX V4.22.1 to generate a project including EHT and Lwip. The debugging has been abnormal. After careful inspection, the following problems were found: 1. The hardware uses LAN8720A, b...[Details]
LAN8720 configuration: IP: 192.168.192.30 Gateway: 192.168.192.1 A high frequency of ARP packets is detected The content of the packet asks for the mac address of 192.168.192.1, and asks the resp...[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]
Security PPP is a new model of urban video surveillance projects: 1) The government and social capital establish a project company in a certain proportion; 2) The project company participates in the ...[Details]
In the Chinese automobile market, the trend of new energy vehicles and driverless cars is leading the transformation of China's automobile industry. As the world's largest automobile market, "Chinese...[Details]
The photovoltaic inverter is the core equipment of the photovoltaic system. Its main function is to convert the direct current generated by the photovoltaic modules into alternating current that meets...[Details]
This program uses the eight-channel ADC single acquisition mode. According to the configuration, ADC12SC will automatically reset after the conversion is completed in the single mode, so it is necess...[Details]
Temperature, humidity and irradiance are must-measure items in the photovoltaic industry. However, most of the current data collection is done by storing data in USB flash drives for offline analys...[Details]
