【Product Introduction】

The EC013 module perfectly combines a display, encoder, and button into a rotary pushbutton display. Its unique innovation and sophisticated manufacturing process provide exceptional reliability and a superior control experience. It is suitable for rotary pushbutton control requirements in many industrial applications of electronic products..

①The module contains an MCU. The TFT display is driven and controlled by the MCU and its peripheral devices.

②The module MCU has the function of communicating with the external HOST MCU according to the specified protocol, and can transmit control commands and display information to each other.

③The module's GUI (graphical interface) can be stored in the submodule's flash memory (flash size: 128 Mbytes) and can be customized according to the product application.

④There is specialized software that can efficiently develop beautiful graphics and complex control GUIs.

【Frequently Asked Questions】

】What are the differences in the use of 8-bit and 16-bit data interfaces of MCU interface (i8080)?

The differences between 8-bit and 16-bit MCU interfaces are as follows:：

1.Since the color screen data is 16 bits to light up one pixel, the 8-bit interface needs to be sent twice, first the high 8 bits and then the low 8 bits. However, the 16-bit interface only needs to be sent once to light up one pixel.

2.On the hardware interface, 8 bits occupy 8 data ports and 16 bits occupy 16 data ports.

Driving an RGB (TTL) interface LCD requires a CPU with an LCD controller that can generate pixel clock (PCLK), horizontal synchronization (HSYNC), vertical synchronization (VSYNC), data enable (DEN) and an 8-24-bit data port.

The LCD screen with RGB (TTL) interface does not have video memory, so the CPU needs to have a large enough video memory to integrate the data and send it to the display.

Therefore, STM32F103 does not have LCD control and cannot drive the LCD display of this interface.
