1. RS-232 RS-232-C is a serial physical interface standard established by the Electronic Industry Association (EIA) in the United States. RS stands for “Recommended Standard,” 232 is the identification number, and C indicates the revision number. Its full name is “Serial binary data exchange interface technology standard between Data Terminal Equipment (DTE) and Data Communication … Read more
NXP has launched the smallest member of the LPC55 series MCU family, the LPC55(S)0x series. As the smallest sibling in the LPC55 series family, upon closer examination, you will find that the LPC55(S)0x indeed possesses some impressive capabilities. Especially when I saw the official reference price of $10 for the LPC55(S)0x, I couldn’t help but … Read more
The RS-485 interface forms a half-duplex network, typically using a two-wire system with shielded twisted pair transmission. This wiring method allows for a bus topology structure, enabling up to 32 nodes to be connected on the same bus. Initially, data was output as analog signals for simple process quantities, and later, the RS-232 interface was … Read more
