The display program edited by the user must be initialized at first, otherwise the module cannot be displayed normally. The following two initialization methods are introduced:
1. Initialize with internal reset circuit
The following instructions are executed during the initialization process.
Clear screen (DISPLAY CLEAR);
Function setting (FUNCTION SET);
DL = 1: 8Bit interface data;
N = 0: 1 line display;
F = 0: 5 & TImes; 7dot glyphs;
Display on/off control (DISPLAY ON/OFF CONTROL)
D = 0: display off; C = 0: cursor off; B = 0: blanking off
Input mode setting (ENTRY MODE SET )
I/D = 1: (incremental): S = 0: no shift:
2. Software reset
If the circuit power supply cannot meet the requirements of the reset circuit, then the initialization is implemented by software. The process is as follows:
