Hi, I'm searching for a LCD, witch is compatible with the STM32L0.

I need to find a very cheap small Display. Of course I would prefer a character display.

Is it possible to drive a character display without a controller (like HD44780)?

Are there some more information about the LCD interface of the STM32L0?

Thank you!

For inspiration, have a look at the DISCOVERY board for STM32L1 http://www.st.com/web/catalog/tools/PF250990 . Note, that VLCDmax=3.6V, so you can't use the 5V ''glasses''.

Hi Jan,

Thank you for your reply.

The glasses might be the cheapest way, but not very comfortable.

I saw the epaper here:

http://www.st.com/web/catalog/tools/FM116/SC959/SS1532/LN1848/PF260319?sc=stm32l0-discovery

Unfortunately they are too expensive for my application.

But I was wondering about the interface, because it's a graphical display.

For my application a 8x2 character LCD would be great.

I would like to drive it without the display controller to reduce costs.

Yes, you trade comfort for price, when you use a LCD module with controller.

The e-paper is a module *with* controller. In fact, you can't drive anything but a plain 3-V LCD ''glass'' with the built-in LCD controller - other displays such as the e-paper and OLED all require relatively exotic voltages and timing.
