Development of A New Type of Laser and Wireless Network Controller
Abstract: The system uses STM32F103V8T6 as the control center, and Ethernet module, driver module, laser receiving amplifier and limiting module, power management module and other parts together to complete the coordination role, Ethernet laser transmission function. Driving power of the whole system by using STM32 SCM configuration mode of IP113ALF working parameters, MAX3263 configuration, and the configuration parameters are stored in a EEPROM chip ATMEL24C04 for IP113ALF power on initialization, signal intensity and STM32 read the receiver MAX3964 detected, and through the serial port and the host computer communication. In the system power circuit, power supply circuit adopting the high efficiency switching power supply chip LM2596-5 and peripheral devices which provide 5V regulated power supply, while the use of ASM1117 3v3 and ASM1117 2v5 regulator composed of multi voltage power supply system.
