LIU Yong, WANG Xue-jun, KONG Xin-wei, ZHOU Chen-chen. Touch screen display design based on UCGUI[J]. , 2014,29(5): 739-744 DOI: 10.3788/YJYXS20142905.0739.
but the interface design is a difficult problem. In order to simplify the interface design
this paper developed a smart LCD touch screen. From two parts of hardware and software
the hardware part mainly divides into the selection of the design of LCD controller
touch screen controller
a main controller design. Software part includes UCCGUI transplantation to the establishment of the main controller
the user graph database and the touch screen and graphical interface design of monitoring program. As main control chip
LCD screen choose RA8875 of a pause with STM32103VET6 as main control chip
using RS232 communication technology to rea-lize the upper machine and lower machine communication.The schematic drawing
the PCB board production
electrical components of the welding and the program operation of this design have been monitored and debugged step by actually
and it has realized the intelligent effect of simple easy to operate.
