Hi
Try to drive the LCD with the PSoC4 MCU.
An example post of driving a 1/3 DUTY 1 / 2BIAS 3com x18 seg LCD using PSoC 4100S (CY8C4146LQI-S433).
Tools
LCD（HD18253T）
PSoC4（CY8C4146LQI-S433）
Use the following as the board of CY8C4146LQI-S433.
Connection, verification
Use the above tools to connect the PSoC 4 MCU to the LCD.
The details of the connection are shown below.
The LCD consists of 4 7 segments and 15 Bars.
LCD display communicates with EZI2C and is controlled from the Bridge Control Panel of the PC.
Attach the HD18253T.iic file.
If you select all the Editor screens of the Bridge Control Panel and click "Repeat", the weight of 500ms is inserted, so the display will be updated at 500ms intervals.
The PSoC4100S controls the LCD by PWM. Please refer to AN87391
Best Regards
Haya
