2.8-inch Intelligent Liquid Crystal Module

      EzUILet028 is one of the EzUI series serial intelligent display modules. The module display is 2.8-inch (diagonal) color TFT display, 240×320 dot matrix, 16-bit color depth; the module has 4M bytes of resource memory inside. The module requires 3.3V DC for

      The external interface of the module is a serial UART (TTL level) interface. The interface is simple and easy to operate. It can be easily and simply interfaced with various MCUs. The biggest feature of the EzUILet series modules is that they are easy to use and feature-rich, and users can use them easily. Users can use the interface development tool software (EzUITool) to design, edit, control, and respond to the human-machine interface. Copy the resource files generated by the tool software into the EzUILet series module to achieve the required human-computer interaction interface. Designed without the need for programming control of the microcontroller or other controller. In order to meet the special requirements of users, the EzUILet series modules retain most of the display control commands (similar to the MzTH series modules), so that users can more freely control the module display. EzUILet series and EzUI series: EzUILet series modules are derived from EzUI series modules and belong to EzUI series modules. Compared with EzUI series modules, EzUILet series streamline the properties of some controls, and change the module USB device interface to virtual serial port, write resource files. The entry method is different from the original EzUI series; the EzUILet series module also reduces the capacity of the resource memory to make it more reasonable and reliable. The touchless version of the EzUILet series requires the user MCU to send key messages, and these key messages trigger the events of the module's internal GUI system, which is the biggest difference from the touched EzUI series modules. The naming of the individual controls in the GUI system of the EzUILet series module is still named using the EzUI family of modules.
