Problem with STM32L0538-DISCO [e-PAPER]

[VEGA1]

Hi,

I have a problem with running the embedded e-paper display in STM32L0538-DISCO. I can't find any example working on STM32CubeIDE. I have tried to write the code myself but it is quite complicated.

So I would like to ask if someone has any simple example, which shows some graphic on the e-paper display and could share it.

I will be grateful for all sources.

it uses drivers from

and

As an experiment, I've extracted them into a minimalistic non-Cube/CubeMX example here.

Hello @VEGA​ and welcome to the Community 🙂

You'll probably want to review the Demo available within STM32CubeL0 at this path : \STM32Cube_FW_L0_V1.12.0\Projects\32L0538DISCOVERY\Demonstrations\SW4STM32.

You can import Cube project from SW4STM32 to STM32CubeIDE, for that please follow this UM2579: Migration guide from System Workbench (SW4STM32) to STM32CubeIDE.

Otherwise, this useful Application note, may help you to develop your application: AN4500 How to display size-optimized pictures on a 4-grey level E-Paper from STM32 embedded memory (STSW-STM32152).

Hope my answer helped you!
