STM32L476 with custom segment LCD aka LCD glass aka Passive LCD

Question asked by Silas Valera on Jul 2, 2017

Hello,

 

I have an application where I need the following:

1. Lowest possible power conusmption - in any mode run/standby/sleep - it is a battery powered application

2. The controller also includes segment LCD driver - driving up to min 64 segments

3. The controller also keeps the segment LCD live (no turning off the LCD) in sleep/standby mode 

 

Refering to the reference manual / data sheet for STM32L476, I found that this is a suitable controller I can use for my application.:

Q1. Has anyone any experience using STM32L4 in application for driving segment LCD? Can anyone please help me with any example / document?  

Q2. Further for the segment LCD, how does the common and segment pins layout work?

 

Any primer or document will be really helpful and very much appreciated..

 

Thanks in advance!

best

Silas
