SSD1351 128x128 Color Issue #340

Closed yuniq-neko closed 2 years ago

yuniq-neko commented 2 years ago

Type of Raspberry Pi

Raspberry Pi 4B (4GB)

Linux Kernel version

Linux RPi-Dash-Cluster 5.15.32-v8+ #1538 SMP PREEMPT Thu Mar 31 19:40:39 BST 2022 aarch64 GNU/Linux

Expected behaviour

RGB = RGB

Actual behaviour

RGB ≠ RGB

Red and Blue seem to have swapped, resulting in the palette becoming "BGR".

If you look here (https://luma-oled.readthedocs.io/en/latest/api-documentation.html#luma.oled.device.ssd1351) at the API docs, there is a bgr= flag you can set to true. This should resolve the issue.

Apologies on the delay on responding to this, adding --bgr does indeed fix the issue. :)
