A typical modern communications signal chain consists of a transmit and receive side, both of which require RF (radio frequency) power monitoring and control (Figure 1). Currently, RF power is usually...
In the control circuit, should the contactor (including relay) coil voltage be 380 or 220? I searched online, but there seems to be no authoritative answer. My humble opinion: If the control circuit i...
Is there an API to turn off DHCP? Or is there any program to do it? Because I am working on a project recently, I hope to modify the IP, SUBMASK, and GATEWAY addresses by calling a program, and I don'...
If IIC or SMBUS is enabled on stm32f103, is the SMBA pin in the main function or the multiplexed function? If it is in the multiplexed function, can it still be used as a normal IO? If it cannot be us...
