Basic Setting
To drive the LCD module correctly and provide normally display, please use the following setting
- ADC = 0 (normal)
- SHL select = 1 (reverse)
- LCD Bias Select = 1/9
- Initial Display Line = 0
- Entire Display ON/OFF = OFF (normal)
- Reverse Display ON/OFF = OFF (normal)
- Set Power Control Set:
voltage follower = ON, voltage converter = ON, voltage regulator = ON
- Built-in OSC = ON
- Display ON/OFF = ON
Note:
*1. These setting/commands should issue the LCD module while start up.
*2. See the Display Commands section for details.
5.2 Resetting the LCD module
The LCD module should be initialized by using /RESET terminal.
While turning on the VDD and VSS power supply, maintain /RES terminal at LOW level. After the
power supply stabilized, release the reset terminal (/RESET=HIGH)
