Crate eink_waveshare_rs

A simple Driver for the Waveshare E-Ink Displays via SPI

This driver was built using embedded-hal traits.

Requirements

SPI

• MISO is not connected/available
• SPI_MODE_0 is used (CPHL = 0, CPOL = 0)
• 8 bits per word, MSB first
• Max. Speed tested was 8Mhz but more should be possible

Other....

• Buffersize: Wherever a buffer is used it always needs to be of the size: width / 8 * length, where width and length being either the full e-ink size or the partial update window size

Examples

use eink-waveshare-rs::epd4in2::EPD4in2;

let mut epd4in2 = EPD4in2::new(spi, cs, busy, dc, rst, delay).unwrap();

let mut buffer =  [0u8, epd4in2.get_width() / 8 * epd4in2.get_height()];

// draw something into the buffer

epd4in2.display_and_transfer_buffer(buffer, None);

// wait and look at the image

epd4in2.clear_frame(None);

epd4in2.sleep();
