I have been studying analog chip design for microelectronics at Fudan University for five years, and I have been working for five years now. During this period, I have listened to the advice of many e...
The following are the test results of 433Mhz and zigbee. The modules purchased are all mainstream and most shipped modules from TI.
1.1 CC1101:The communication frequency of CC1101 is 433MHz. Its adva...
[size=4]Circuit and working principle: [/size] [size=4]When the positive half cycle of the input voltage passes, the detector tube VU2 is turned on to charge the capacitors C1 and C2 until the peak va...
Recently, there is a small topic: Use CPLD and STM32 microcontroller to design a board with 12 signal input interfaces (each interface is independent and has its own fixed address). When 1 to 4 square...
At present, analog signal interfaces dominate, while digital signal interfaces are rare. Nowadays, LCD TVs are becoming more and more popular, so digital signals have become the mainstream. Among them...
