Hi,

Would you be interested in writing a post about this project on LittelvGL's blog?

A short introduction of MangOH and a getting started guide with it and LitteveGL would be very welcome!

If you are interested, please have a look at https://blog.littlevgl.com/2018-12-06/contributing#writing-a-blog-post-about-your-experiences

Hi Gabor Kiss-Vamosi

For Littlevgl framebuffer What is monochrome display that you support?

I saw the way you draw pixel quite different with waveshare e-ink. It make character is mirror when displaying

Current Framebuffer 1 bit per pixel: left shift bit

            fbp8[byte_location] &= ~(((uint8_t)(1)) << bit_location);
            fbp8[byte_location] |= ((uint8_t)(color.full)) <<

bit_location; }

with Waveshare:source. Right shift bit. fbp8[byte_location] &= ~(((uint8_t)(128)) >> bit_location); fbp8[byte_location] |= ((uint8_t)(color_p->full << 7)) >> bit_location;

It make

Thanks Thong Nguyen

It's possible that you display controller maps bytes (bits) to pixels in a different order. Only your driver needs to be adjusted like you did.
