background After the hardware engineer completed the PCB and schematic design, the routine was modified according to the tutorial of Zhengdian Atom to verify the correctness of the hardware.  STM32F...[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]

1. Initial understanding of FSMC: FSMC consists of 4 modules: (1) AHB interface (including FSMC configuration register) (2) NOR flash memory and PSRAM controller (when driving LCD, LCD is like a PSRA...[Details]

In 1952, Bell Labs built a 6-foot-tall automatic number recognition machine called "Audrey", which could recognize the pronunciation of the numbers 0 to 9 with an accuracy of more than 90%. And its...[Details]

Since the first draft of the 5G NR standard was officially launched at the end of 2017 , the 5G commercialization process has taken a substantial step forward. From that moment on, mo...[Details]

According to MEMS Consulting, single-chip radar system-on-chip (SoC) is becoming one of the most popular new sensors . Its widespread adoption in automobiles has greatly increased sales, thereby pr...[Details]

When STM32 uses JTMS (PA13) and JTCK (PA14) as normal I/O ports, add the following code before initialization (the order cannot be reversed):   RCC_APB2PeriphClockCmd(RCC_APB2Periph_AFIO, ENABLE); G...[Details]
