Hello, i need to design a driver to the LCD described on the following image.




I'm using a frequency generator with a 5Vpp TTL signal to activate one segment or word of the LCD and commuting the corresponding COMM's but i have many interference, so...

- I don't know if i'm using this correctly.
- How i can controll all the LCD with uC.


So i would like you to help me with this.

Thanks a lot,

Ricardo
 

This is a multiplexed LCD which needs special multiplex driver generating multilevel waveforms for all LCD pins, review e.g. PIC16F19185 datasheet to see how it works.
