[size=4][color=#000000][backcolor=white] In many engineering applications, PWM waves (pulse width modulation) are needed, such as motor speed regulation, temperature control and power adjustment. This
In any switching power supply design, the physical design of the PCB board is the last link. If the design method is not appropriate, the PCB may radiate too much electromagnetic interference, causing
Seeing that STM32+RA8875+emWin was so popular for human-machine interface, I also used FPGA to imitate RA8875 and made a graphics LCD controller. The main system architecture of the graphics LCD contr
What is 5G technology and what impact will it have on positioning technology? Every dayfirst, let us introduce you to 5G. This is the fifth generation of mobile connectivity. The earlier 2G, 3G, and 4
Today, MicroPython has made an important update, which can use the system's extended SDRAM. At the same time, SDRAM support has been added for multiple ST official Discovery development boards. [list]
