Communication protocols serve as a “common language” between two devices. Data exchange can only proceed smoothly if both parties use the same rules and settings. UART is a point-to-point (P2P) hardware communication method, where the connected ends can be a microcontroller and anothermicrocontroller, a sensor, or a computer (with conversion). Before data transmission begins, both … Read more
In my previous sharing, I mentioned the lesson preparation ideas for the eighth-grade class on ‘Interconnected Communication of the Internet of Things’. However, when it came time to actually teach this lesson, I overturned my previous ideas. I reviewed the content of the textbook and specifically focused on the Renjiao Edition’s lesson on ‘Diverse Data … Read more
The safe and efficient operation of road traffic systems highly relies on real-time and accurate meteorological data support. Weather disasters such as rain, snow, fog, and road icing are among the main causes of traffic accidents. As a core node in the traffic meteorological service system, road weather monitoring stations integrate various specialized meteorological sensors … Read more
Theoretically, the bandwidth of the RS485 bus is calculated based on the serial port rate, but in practice, there is a 20ms error.Theoretically:At 9600bps, transmitting 1 byte requires sending 10 bits (1 start bit, 8 data bits, 1 stop bit), so the time required to transmit 1 byte = 1 / 9600bps * 10bit = … Read more
