I recently bought this display that is 64x32 pixels and uses the SSD1306 driver. When running the LVGL Basic Sample with the Zephyr ssd1306_128x64 shield, the display works, but shows only the bottom center of what would show up on the 128x64 display. Zephyr does not have a ssd1306_64x32 shield unfortunately, so I have tried changing the width and height in the devicetree like from 128->64 and from 64 ->32 like this:
nrf52dk_nrf52832.overlay:
/ {
chosen {
zephyr,display = &ssd1306_ssd1306_128x64;
};
};
&arduino_i2c {
status = "okay";
ssd1306_ssd1306_128x64: ssd1306@3c {
compatible = "solomon,ssd1306fb";
reg = 0x3c;
width = 64;
height = 32;
segment-offset = 0;
page-offset = 0;
display-offset = 0;
multiplex-ratio = 63;
segment-remap;
com-invdir;
prechargep = <x22;
};
};
