The following example connects the MT6103IP touch screen to a Panasonic PLC; other brands of PLCs can be referenced. 1. Determine the connection scheme as follows: 2. Hardware wiring Below are the wiring terminals of the touch screen, which has 9 pins, allowing for one group of RS232 and another group of RS485. 1) RS232 … Read more
In microcontroller development, protocols such as UART, I2C, and RS485 are commonly used, and understanding them can be somewhat ambiguous. This article organizes these concepts. The reading time is approximately 10 minutes. UART Universal Asynchronous Receiver-Transmitter The UART port refers to a type of physical interface (hardware). UART is an asynchronous, full-duplex serial bus. It … Read more
In the previous article “UART Communication Interface Protocol – UART (I) Protocol Basics”, we briefly and meticulously describedUART configuration items and the signal timing of the communication process. This article will continue to introduce some interface specifications used by theUART interface under different electrical characteristics. 1. Introduction In fact,UART only defines the signal timing without … Read more
