Pre-baked configurations ¶

ssd1675a_config_t ssd1675a_config_buydisplay_red_2_9_inch_e_ink_display_module¶

Configuration for BuyDisplay Red 2.9” inch e-Ink Display Module 296x128. Should also work with Yellow 2.9” e-Paper Display Module 296x128 for Arduino,Raspberry Pi <https://www.buydisplay.com/yellow-2-9-inch-e-paper-display-module-296x128-for-arduino-raspberry-pi-1>_.

Values extracted from BuyDisplay’s provided example code.

ssd1675a_config_t ssd1675a_config_buydisplay_red_2_9_inch_e_ink_display_module_fast_update¶: Variant of ssd1675a_config_buydisplay_red_2_9_inch_e_ink_display_module but with custom voltages and LUT for ~3x faster update (~6s instead of ~18s).

ssd1675a_config_t ssd1675a_config_buydisplay_black_2_9_inch_e_ink_display_module¶

Configuration for Black 2.9” inch e-Paper Display Module for Arduino,Raspberry Pi.

Values extracted from BuyDisplay’s provided example code. Unfortunately, BuyDisplay example code does not provide LUT for this BW display (only for BWR/BWR), but ssd1675a_lut_bw_adafruit seems to work just fine.

See also: ssd1675a_writeLut(), ssd1675a_lut_bw_adafruit and ssd1675a_lut_bw_partial.

Driver ¶

const display_t ssd1675a¶

SSD1675A display driver.

See also: eglib_Init().
See also: Datasheet.

Functions ¶

These functions can be used exclusively with eglib_t initialized with ssd1675a.

ssd1675a_lut_t ssd1675a_lut_bw_adafruit¶

Full update LUT for Adafruit_CircuitPython_SSD1675 <https://github.com/adafruit/Adafruit_CircuitPython_SSD1675>_.

This driver is for a different controller SSD1675, but the LUT should be compatible with similar BW displays.

ssd1675a_lut_t ssd1675a_lut_bw_partial¶

Partial update LUT for ssd1675a_config_buydisplay_black_2_9_inch_e_ink_display_module.

This fast screen update causes no flickering, at the expense of image ghosting.

Warning: doing repeated partial updates without issuing full updates once in a while will permanently polarize the display causing permanent damage as image burn in!

void ssd1675a_writeLut(eglib_t * eglib, ssd1675a_lut_t * lut)¶

Set LUT.

Parameters

lut – LUT register (70 bytes).
