I have a STN LCD (that have only 24 segment and 1 common)-at 3.3 volt.
Can I use stm32f103 to drive it directly?(by 100Hz toggling segments with respect to common pin) Is there any note for this method? Is there any problem in longtime for aging of LCD?2012-06-11 02:17 AM
Pls see if AN2656 can help you
Did you evaluate STM32L which has inbuild LCD controller2012-06-11 02:18 AM

The STM32L does not have CAN controller and I need it too on my MCU.
My application need CAN and LCD segment driver at the same time. number of segments is low(24) and I have one common on LCD.I think I can drive it with stm32f103cbt6. I only worry about its long term operation.Is there any note to be considered on HW and FW?2012-06-11 03:26 AM
Did you see already AN2656 put in my post ?
There is no long term problems in SW driving as per my experience2012-06-12 12:54 AM
thanks,I saw it.
