Recently a lcd12864 + matrix in buttons and so on a LCD module, I want to ask whether to press a button when the cursor to a specific location and read the position shown in the value, and then save the value behind the convenient continue to use, how to write the program

CodePudding user response:

Only LCD12864 of lattice pattern, lattice data read out just, couldn't read the display of digital or character value, you don't want to this function, if it is with functions of character pattern of LCD12864, it can have a try, it is possible, this requirement can be set in the program memory area, save the display content and key position, completely independent of LCD12864 to achieve the required function by the software, let LCD12864 only responsible for display,
