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]

When designing a product, if the application environment's requirements for power isolation are not considered, the product will be unstable due to improper design, and even high voltage may damage t...[Details]

1. FSMC Brief           FSMC, the Flexible Static Storage Controller, is capable of interfacing with synchronous or asynchronous memories and 16-bit PC memory cards. The FSMC interface of STM32 s...[Details]

1. Function and purpose         There are two pins BOOT0 and BOOT1 on each STM32 chip. The level status of these two pins when the chip is reset determines which area the program starts from after th...[Details]

     12864 LCD parallel port driver is more commonly used, but considering that sometimes the IO port of the microcontroller or MCU is limited, the serial driver method can be used. The following is ...[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]
