5. Function specifications
5.1 Basic Setting
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)
5.3 Adjusting the Display Contrast
This LCD module equipped with latest digital contrast adjustment function.
Its display contrast could be adjusted by MCU command.
(Please see the command tables for details)
It is recommended to provide a contrast adjustment interface for end-user,
where the best display result could meet the individual preference in mass production.
