Write_com (0 x80 + 0 x53);

For (num=0; Num<16. Num++)

This is part of the above 1602 display character code, want to ask about the middle order code 0 x80 + 0 x53 why is a newline, behind the 0 x18 is what meaning, beginners MCU have so many don't understand

Write_com complete LCD1602 instructions
Write_com (0 x80 + 0 x53) is to set up DDRAM addresses, need DB7 constant is 1 (0 x80); Order code 0 x80 + 0 x53 not line, but the character data is written into the address 0 x53 RAM in
Write_com (0 x18) is to set the display instruction or the cursor movement direction, 0 x18 said display content left shift, the cursor does not move
