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]

From last year to now, competition in the photovoltaic inverter industry has become increasingly fierce. In addition to the introduction of new products, various marketing and promotion methods hav...[Details]

When Amazon quietly launched a product called Elastic Computing Cloud 12 years ago, the Internet industry in China, across the ocean, also ushered in an unprecedented development opportunity. Let's...[Details]

Household photovoltaic power stations mainly utilize idle resources on existing household buildings, such as roofs, wall facades, balconies, courtyards, etc., to install and use distributed photovo...[Details]

sprintf is a function in the C language library that converts data types. There is a situation where In 51 MCU, define unsigned char temp; Then I want to use the serial port to print out temp in deci...[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]

The clock system of STM32 can be directly summarized in a diagram (from the STM32F10X reference manual).  The following is an analysis of this diagram 1. STM32 input clock source 1.1 Function of cl...[Details]
