4.3 inch color screen serial HMI,

Release time:


In order to facilitate the convenience and simplicity of customers using color screens, the company's research and development team has newly developed a 4.3-inch color screen serial HMI connection method,Serial port HMIThe equipment is packaged well. HMIAfter the underlying function, through the serial port.(USART 232)with users MCUto interact, such MCUCan pass at any time USARTSend instructions to notify the device to switch a page or change a page.The properties of the component. Equipment can also be passed at any time.USART notifies the user MCU that the operator has currently touched a certain component on the page or that the device has currently entered a certain page.

For developers, serial HMI is the simplest display solution. First of all, he has no requirements for the user's hardware like the MCU bus screen, and secondly. He has no speed bottleneck, because the display of the interface is implemented by the device itself. The user MCU only sends instructions and does not need the underlying driver. Again, for the display of the human-machine interface layout and most of the logic (such as interface background, button effects, text display, etc.). All do not need the user's MCU to participate, using the upper software provided by the device, a few mouse clicks on the computer to complete. After making the resource file and downloading it to the screen, it can run automatically. The rest is USART interaction (the user MCU modifies the content on the interface through simple object operation instructions during operation).
