error MSP430: not enough memory`

somehow I am not able to work with e-paper. some controllers don't have enough memory for 2.7 inch displays. I want some solution with low cost low power micro controllers that can effectively display text messages on 2.7", just like what GFX library. Is there any way?

Not with the current code as it is using bit mapped graphics and needs enough memory for a full pixel copy of the panel. I see two possibilities

• Use a text buffer an modify the code to render the characters on the fly assuming there is enough flash to hold the font
• use an external SPI RAM to hold the frame buffers; maybe even need SPI FLASH to hold fonts depending on how small a microcontroller you are using
